Introduction: Why Learn to Create Long Videos with Consistent Characters Using VEO 3?

If you want to break through the noise and produce video content that holds attention, consistency is your secret weapon.
This course is about more than just mastering a tool,it's about building workflows that let you create engaging, professional-looking long videos featuring the same characters across different scenes, even when the platform tries to get in your way. We’ll strip back the hype, get clear about the real-world challenges of using VEO 3, and build a repeatable process that unlocks the creative power of AI for storytellers, marketers, educators, and anyone who wants to scale video production while keeping it human.

You’ll learn how to:

• Bypass VEO 3’s built-in limitations that frustrate most users
• Engineer prompts that produce visually consistent characters, every time
• Replace backgrounds seamlessly for dynamic scene changes
• Work efficiently in short, manageable segments to save time and money
• Edit your clips into polished, long-form video content

Understanding the Challenge: VEO 3’s Native Limitations

Before you build anything powerful, you have to know exactly what’s holding you back.
VEO 3 is a promising AI video generation platform, but its default features put up roadblocks for anyone serious about quality and consistency. Let’s start by getting clear about the two main pain points:

• VEO 3 Flow Feature Drawbacks:
  The “Flow” feature in VEO 3, designed for extending videos, only works with V2. Unfortunately, V2 outputs visuals that are blocky, distorted, and lack sound. If you use Flow, your video might be longer, but the image quality tanks and you lose crucial audio, making it unfit for professional or even basic content.
• Frame-to-Video Upload Restrictions:
  In certain regions (including the UK), VEO 3’s “Frames to Video” feature blocks users from uploading any images that contain people. That means you can’t just upload a photo of your actor or character and animate it. You’re forced to generate images directly inside VEO 3, which limits flexibility and raises the bar for prompt engineering.

Example 1: Imagine you want to create a training video featuring a consistent instructor. If you use the Flow feature, your character starts to lose their face, body proportions, and even their clothes as the video continues. The result is jarring and unusable.
Example 2: Suppose you have a great still photo of your brand mascot and want to animate it. If you’re in a restricted region, VEO 3 simply won’t let you upload this image,forcing you to find workarounds.

Key Insight: The platform is powerful, but if you rely on its default settings, your content will fall short. The only way forward is to hack the system,by understanding how to control what VEO 3 generates, and how.

The Solution: The Green Screen Character Consistency Workflow

If you want to create magic with AI video tools, you need to blend machine logic with human creativity.
The method covered here is a multi-step process that guarantees character consistency, even as you switch scenes, backgrounds, and actions. Here’s the big idea:

1. Generate detailed character images inside VEO 3, always against a plain green or white background.
   This acts as a “green screen” the AI can easily cut out and replace later.
2. Engineer prompts using ChatGPT that split the “character description” from the “action.”
   By separating who the character is from what they’re doing, you tell VEO 3 to keep the look consistent across every scene.
3. Use “Frames to Video” to create short video segments, each time instructing VEO 3 to swap out the background with a new scene in the very first frame.
   This trick ensures the character appears in different places, all while looking exactly the same.
4. Edit and assemble these short segments into a long, cohesive video, trimming out any leftover green screen frames.
   The end result: One long video, one consistent character, many dynamic scenes.

Example 1: You want a 2-minute explainer video where your character moves from an office to a park to a city street. Using this method, you generate the character once on a green screen, then prompt VEO 3 to swap backgrounds for each segment,keeping the character’s look identical.
Example 2: You’re producing a children’s story video. The same cartoon hero appears in a forest, a castle, and a spaceship. Every shot starts from the same AI-generated “green screen” character, so the hero never changes shape or color, even as the scenes shift.

Step 1: Accessing VEO 3 and Setting Up Your Project

The best workflow starts with clarity and organization.
Let’s walk through how to get into VEO 3 and prepare your workspace:

• Finding VEO 3:
  Open your favorite search engine and look up “VEO 3.” Follow the official link to the platform.
• Creating a New Video Project:
  On the VEO 3 homepage, look for “Try Flow” or “Create with Flow.” Click through, but remember, you won’t use the Flow feature for actual generation,just to create a new project.
• Switch to “Frames to Video” Mode:
  Once inside your project, find the option to switch from “Text to Video” to “Frames to Video.” This is your main workspace for this method.

Tips: Bookmark the VEO 3 page for easy access, and organize your project folders on your device for storing images and video clips. Name them clearly (e.g., “Character_GreenScreen”, “Scene1_Office”, “Final_Clips”).

Step 2: Engineering Prompts for Consistent Characters Using ChatGPT

The secret to AI consistency is in the prompt,not the platform.
Here’s how to use ChatGPT to structure prompts that force VEO 3 to generate the same character every time, no matter the scene:

1. Write a Detailed Character Description:
   Use ChatGPT to produce a paragraph that covers:
   • Name
   • Physical features (hair, skin, eyes, build, height)
   • Nationality, age, gender
   • Outfit and clothing colors
   • Accessories (glasses, jewelry, hats, etc.)
   Example: “A 35-year-old Japanese woman named Yuki, with straight black hair in a ponytail, almond eyes, light skin, wearing a navy blue business suit, white blouse, and silver-rimmed glasses.”
2. Explicitly Split the Prompt into “Character” and “Action” Sections:
   Ask ChatGPT: “Split the prompt into two sections,first, a ‘Character Description’ (all physical and clothing details), second, ‘Action’ (what the character is doing or saying).”
   Example:
   Character Description: “A 35-year-old Japanese woman named Yuki, with straight black hair in a ponytail, almond eyes, light skin, wearing a navy blue business suit, white blouse, and silver-rimmed glasses.”
   Action: “Standing confidently at a podium, speaking to an audience, smiling.”

Why It Matters: If you only describe the action or scene, VEO 3 will improvise the character’s look every time. But if you separate the character’s description, you “lock in” their appearance for every segment.

Example 1: For a fantasy story: Character Description,“A young elf boy with curly red hair, emerald eyes, pointed ears, wearing a green tunic and brown boots.” Action,“Walking through a magical forest, looking amazed.”
Example 2: For a tech explainer: Character Description,“A middle-aged Black man with a shaved head, athletic build, wearing a red hoodie and black jeans.” Action,“Typing on a laptop in a modern office environment.”

Best Practice: Always use the same character description for every prompt in your video sequence. Only change the “Action” section to shift what they’re doing or where they are.

Step 3: Generating Green Screen Character Images in VEO 3

The green screen method is the backbone of this workflow.
Instead of trying to upload an image (which is blocked in many regions), you generate your character images directly within VEO 3, on a plain background. Here’s how:

1. Switch to “Generate Image” (Not Upload):
   In “Frames to Video,” click “Generate Image.” Paste your “Character Description” prompt only. Do not include the action yet.
2. Specify a Plain Green or White Background in the Prompt:
   For best results, add to your character description: “standing against a plain green background” or “on a solid white background.”
   Example: “A middle-aged Black man with a shaved head, athletic build, wearing a red hoodie and black jeans, standing against a plain green background.”
3. Request Multiple Shots:
   Ask ChatGPT to generate prompts for both “full body portrait” and “mid-shot from waist up.”
   Example: “A young elf boy with curly red hair... full body portrait on a plain green background.” Then, “...mid-shot from waist up on a plain green background.”
4. Choose the Best Image:
   VEO 3 typically generates four image options. Select the one where the character’s pose, facial expression, and lighting are most neutral and clear.

Example 1: For a video featuring a businesswoman, generate her standing straight (full body) and sitting at a desk (mid-shot), both on a green background.
Example 2: For an animated animal mascot, generate both a standing and a waving pose, on a white background.

Tips: Neutral poses work best for later action overlays. Save all generated images to your VEO 3 library for easy access.

Step 4: Creating the First Video Segment,Combining Character and Action

Now you merge the character with their first action and background.
Here’s how to turn your green screen image into a dynamic video:

1. Return to ChatGPT for Your First Video Prompt:
   Ask: “Using the character description, write a VEO 3 video prompt where the character performs the following action: [Action]. Start the video by replacing the plain green background in the uploaded image with [desired scene], and have the character [say/do something]. Make sure the new background appears at the start of the video in the first frame.”
   Example: “Replace the plain green background in the uploaded image with a bustling city office. At the start of the video in the first frame, have Yuki walk to a desk and greet the audience, saying ‘Welcome to today’s workshop.’”
2. Paste This Prompt into “Frames to Video”:
   Ensure your selected green screen image is loaded as the first frame.
3. Choose Your Generation Setting:
   VEO 3 offers “Fast” and “Quality” modes. “Fast” gives you quick results but can be inconsistent. “Quality” takes longer but sometimes produces better visuals. Experiment and see which works best for your prompt.
4. Generate a Short Clip (10 seconds):
   Set the duration to 10 seconds,not longer. This keeps costs down and allows quick testing.

Example 1: “Replace the plain green background in the uploaded image with a magical forest at sunrise. In the first frame, have the elf boy walk forward and wave.”
Example 2: “Replace the plain green background in the uploaded image with the inside of a hot air balloon. At the start of the video, have the character look around and say, ‘What an incredible view!’”

Tip: Always include “replace the plain green background” and “at the start of the video in the first frame” in your prompt. This prevents the green screen from showing up at the beginning of your video.

Step 5: Generating Subsequent Segments with Dynamic Backgrounds

This is where you unlock scene changes and keep your character visually identical.
For every new scene, repeat the process:

1. Select a Green Screen Image from Your Library:
   Always start with the same character image (or another from your green screen set).
2. Ask ChatGPT for a New Action and Background Combination:
   Example prompt: “Write a VEO 3 prompt that instructs the AI to replace the plain green background with a sunny park scene, and have the character sit on a bench and read a book. The new background must appear at the start of the video in the first frame.”
3. Paste and Generate a New 10-Second Video Clip:
   Use “Frames to Video,” select your character frame, and generate the clip.
4. Repeat for Each Scene:
   Generate as many segments as you need, changing only the action and background.

Example 1: For a travel vlog, your character appears at a London street, then on a beach, then at a mountain overlook,all with the same face and outfit.
Example 2: For a product demo, your expert appears in a kitchen, then a workshop, then an outdoor patio, always maintaining the same brand-aligned appearance.

Tip: For each segment, keep your prompts consistent in structure. If you’re producing a dialogue, specify exactly what the character should say in each scene.

Step 6: Troubleshooting,VEO 3 Fast vs. Quality Mode

AI models are unpredictable, so flexibility is your friend.
Sometimes “Fast” mode produces better visuals; sometimes “Quality” shines. If your video comes out blurry, distorted, or just “off,” do this:

• If in Fast mode and results are poor, switch to Quality and regenerate.
• If in Quality mode and results are poor, try Fast instead.
• Test both modes for each prompt,what works for one background might fail for another.

Example: You generate a park scene in Fast mode but the character’s face looks “melty.” Switch to Quality,now the face is sharp and the action is smooth.
Another Example: In Quality mode, your city street scene has odd lighting glitches. Fast mode cleans it up.

Tip: Don’t get hung up on the first result. Sometimes it takes two or three tries to get a usable segment.

Step 7: Editing and Assembling Your Long Video

Raw AI segments are a starting point, not the finished product.
Now it’s time to bring everything together in a video editor like CapCut (or any similar tool):

1. Download All Video Clips:
   Save every 10-second segment to your device.
2. Import the Clips into Your Video Editor:
   Open CapCut, create a new project, and drag in all segments.
3. Trim Off the Initial Green Screen Frames:
   The first frame,or sometimes the first half-second,of each video might still show the plain green/white background before the background swap kicks in. Trim this out for every segment.
   Example: If your character blinks in on a green screen before the office appears, slide the start point forward until the new background is in place.
4. Sequence Segments in Story Order:
   Arrange your clips to match the narrative flow you designed.
5. Add Transitions and Effects:
   Use simple fades, sound effects, or overlays to smooth scene changes and keep viewers engaged.
6. Export the Final Video:
   Render your completed long video, ready for upload or sharing.

Example 1: For a five-scene explainer, sequence your office, park, street, boardroom, and home office scenes,trimming each for seamless flow.
Example 2: For a storybook, cut between magical settings, adding gentle crossfades and background music for atmosphere.

Best Practice: Always check the final export for any leftover flashes of green or white. If you spot one, go back and trim a bit more.

Step 8: The Rationale Behind Short Video Segments

Why not just generate a 2-minute video in one go? Because you’ll waste time, money, and creative control.
Here’s why the 10-second segment approach is superior:

• Creative Flexibility:
  Most engaging videos change scenes, shots, or camera angles every few seconds. Short segments let you plan for this, keeping viewers’ attention.
• Cost Control:
  If you try to generate a 1-minute video and VEO 3 messes up at second 45, you just wasted a lot of credits. With 10-second clips, you throw away only what doesn’t work.
• Testing and Iteration:
  You can quickly see what works (and what doesn’t), adjust your prompts, and regenerate only the sections that need improvement.

Example: In a product tutorial, you realize the kitchen scene doesn’t look right. You only need to re-generate that 10-second segment, not the entire video.
Another Example: For a story with a surprise ending, you can test multiple versions of the final clip before locking it in.

Tip: If your story needs longer continuous action, you can splice together several 10-second segments with smooth cuts or transitions.

Step 9: Advanced Prompt Engineering Techniques

Prompt quality is the difference between magic and mediocrity.
Some best practices for getting the most out of ChatGPT and VEO 3:

• Be Ultra-Specific in Character Descriptions:
  The more detail you include, the less “drift” you get between scenes.
  Example: “A 40-year-old Indian man with a short beard, wearing a tailored grey blazer, crisp white shirt, blue tie, black-rimmed glasses, and brown leather watch.”
• Use Exact Commands for Background Replacement:
  Always include “replace the plain green background in the uploaded image with [scene]” and “at the start of the video in the first frame.”
  Example: “Replace the plain green background in the uploaded image with a vibrant Paris café scene at dusk. At the start of the video in the first frame, have the character sip coffee and smile.”
• Structure Prompts for Multiple Characters:
  If you have two or more characters, write separate character descriptions for each, then combine them in the action section.
  Example:
  Character 1: “A young blonde woman in a red dress...”
  Character 2: “A tall Black man in a blue suit...”
  Action: “Both are sitting at a table, laughing and sharing a meal in a cozy restaurant.”
• Spell Out Dialogue and Gestures:
  Tell the AI exactly what you want said or done.
  Example: “Have the character say, ‘Let’s get started!’ while raising a finger and smiling.”

Tip: Keep a template for your prompts so you can copy and tweak quickly as you move from one segment to the next.

Step 10: Use Cases and Practical Applications

Here’s where this workflow really pays off,real-world scenarios.
If you’re wondering how to apply this method, consider these examples:

• Educational Content:
  An instructor appears in different classrooms, labs, and field locations,always the same face and voice.
• Brand Storytelling:
  A mascot or spokesperson moves through different parts of your company, from the factory to the boardroom to events.
• Animated Series:
  Characters remain visually consistent across episodes, even as you change settings from jungles to outer space.
• Marketing Demos:
  A product expert shows off features in different environments, building trust through a familiar, reliable presence.

Example 1: An online language course where the same cartoon teacher guides students through lessons set in various real-world locations.
Example 2: A startup’s explainer video where the same animated founder walks viewers through the company’s journey, stage by stage.

Step 11: Best Practices, Tips, and Common Pitfalls

The difference between amateurs and professionals? Process.
Follow these best practices to get consistently great results:

• Use Consistent Naming and File Organization:
  Save each clip, prompt, and image with clear labels to avoid confusion.
• Double-Check for Green Screen Glitches:
  Scrub through each segment before export to ensure no green/white flashes remain.
• Iterate on Prompts Before Scaling:
  Test your character and background prompts on one or two scenes before generating a full video set.
• Back Up All Assets:
  Store character prompts, green screen images, and final clips in a cloud folder for easy reuse.
• Reference the Glossary:
  Review key terms like “Frames to Video,” “Background Replacement Prompt,” and “Trimming” so you’re never lost in the technical weeds.

Pitfall 1: Mixing character and action details in a single prompt. This causes the AI to change the character’s look each time. Always split them.
Pitfall 2: Forgetting to specify “at the start of the video in the first frame.” This leads to green screen flashes that break immersion.
Pitfall 3: Trying to generate everything in one massive clip. You’ll waste time and budget on failed generations.

Step 12: Sample Full Workflow,Creating a Five-Minute, Multi-Scene Video

Let’s put it all together with an end-to-end example.
Suppose you want to create a five-minute video featuring one consistent character in five different locations.

1. Prompt Generation:
   Use ChatGPT to write a detailed character description. Then, draft five separate “Action” prompts,one for each location.
2. Green Screen Image Generation:
   In VEO 3, generate both full body and mid-shot images of the character, each on a plain green background.
3. Scene-by-Scene Video Generation:
   For each location, use ChatGPT to craft a prompt that tells VEO 3 to “replace the plain green background in the uploaded image with [scene] at the start of the video in the first frame,” and specify the character’s action and dialogue.
   Generate a 10-second clip for each scene.
4. Repeat for All Scenes:
   Produce as many 10-second clips as needed to cover the five minutes. (For five scenes, you’ll need about 30 segments.)
5. Edit and Assemble:
   Import all video clips into your editor, trim out green screen frames, arrange in order, add transitions, and export the final video.

Example: Your character starts in a home office, moves to a conference room, then a city street, a rooftop terrace, and finally a cozy library,all with perfectly consistent appearance and voice.

Frequently Asked Questions

This FAQ provides detailed, step-by-step answers to common questions about creating long videos with consistent characters using VEO 3. It addresses everything from basic setup and workflow to advanced prompt engineering, troubleshooting, and best practices for business professionals looking to efficiently produce high-quality, engaging video content with AI. Real-world examples and actionable advice are included to help you avoid pitfalls and achieve professional results.

What is the main challenge when creating long videos with consistent characters using V3, and how can it be overcome?

The primary challenge is V3's 'flow' feature, designed for long videos, only works with V2, which offers poor visual quality and no sound. Additionally, V3's 'frames to video' feature restricts users in certain countries from uploading images of people to create videos. To overcome this, users should generate character images directly on the V3 platform, specifically using green or white backgrounds, and then replace these backgrounds with desired scenes using AI prompts.

How does one ensure character consistency across multiple scenes in a long video created with V3?

To ensure character consistency, the same initial image of the character (preferably generated on a plain green or white background for easy background removal) is reused for each new video segment. The background and action are then changed through specific V3 prompts, instructing the AI to replace the green screen with the desired new scene and detailing the character's actions and dialogue. This method allows for a consistent character in various settings.

What role does ChatGPT play in this V3 video creation process?

ChatGPT is crucial for generating precise and effective prompts. It is used to:

• Describe characters in detail (skin colour, hair type, nationality, age, gender, outfit, etc.).
• Split image prompts into distinct character descriptions and action commands.
• Generate prompts for creating full-body and mid-shot character images on plain backgrounds.
• Formulate V3 video prompts that instruct the AI to change backgrounds in uploaded images at the start of the video's first frame and define the character's actions and dialogue.

Why is it recommended to create short video segments (around 10 seconds) instead of generating one long video directly?

Creating short, 10-second video segments is advised for several reasons:

• Engagement: It allows for strategic scene and shot changes, making the overall video more engaging.
• Cost-effectiveness: Generating shorter clips prevents wasting resources on long videos that might turn out unsatisfactory, requiring expensive regeneration.
• Quality Control: It enables users to review and refine individual segments, ensuring each part meets their quality standards before final assembly.

What are the key elements of an effective V3 prompt for generating video with character consistency and background changes?

An effective V3 prompt should include:

• Character Description: A detailed description of the character, separated from the action.
• Action: A clear description of what the character is doing and saying in the scene.
• Background Replacement Instruction: Explicit instruction to V3 to "change the background in the uploaded image" at the start of the video, specifically in the first frame, and then specify the "new background" (e.g., "replace the plain green background in the uploaded image with a lively London street scene").

What is the difference between V3 Fast and V3 Quality, and which should be used?

V3 offers both 'Fast' and 'Quality' generation options. There isn't a definitive "better" option, as results can vary. Sometimes V3 Fast produces superior videos, while other times V3 Quality yields better results, and vice versa. Users are encouraged to switch between the two based on the outcome of their generations to find the best setting for their specific video.

How are the individual video clips assembled into a final, long video?

Once all the 10-second video clips are generated, they need to be downloaded and imported into a video editing tool like CapCut. In the editing software, users must:

• Trim out the initial frames of each clip that still show the green or plain background, ensuring the video starts directly with the desired scene and dialogue.
• Arrange the clips in the correct sequence according to the story or idea.
• Add transitions, effects, and any other edits to make the video lively and engaging.
• Finally, export the compiled video.

Why is generating character images on a green or white background essential for this method?

Generating character images on a plain green or white background is crucial because it makes it significantly easier for the AI to detach and remove the background. This clean separation allows users to instruct V3 to seamlessly replace the plain background with any desired scene, maintaining the consistent character against varied backdrops without complex manual editing.

What are the two primary limitations of VEO 3's native features that this method aims to solve?

The first limitation is that VEO 3’s “Flow” feature only works with V2, which produces low-quality visuals and lacks sound. The second is that “Frames to Video” restricts users in certain countries from uploading images with people, forcing image generation on the platform. This method bypasses both by generating character images on plain backgrounds and using AI prompts for background replacement.

Why is it crucial to split the initial image prompt into "Character Description" and "Action" when working with ChatGPT?

Splitting the prompt ensures that the AI can consistently recreate the character’s appearance across scenes, since the “Character Description” remains the same, while the “Action” part can be tailored for each segment. This separation is key for both visual consistency and clear storytelling.

Why is the "generate image" option used instead of "upload an image" for initial character images in VEO 3?

Some countries restrict uploading images containing people due to privacy and AI safety regulations. The "generate image" option within VEO 3 allows users to create character images directly on the platform, complying with these restrictions and ensuring compatibility for subsequent video generation.

What is the purpose of generating character images on a plain green or white background?

A plain background acts as a digital “green screen,” allowing the AI to easily separate the character from the background. This makes background replacement seamless and ensures the character remains visually consistent across different scenes and settings.

What specific phrase must be included in the VEO 3 video prompt to ensure the background is replaced?

The video prompt must include: “replace the plain green background in the uploaded image with [new background description].” This direct instruction tells VEO 3 exactly how to handle the background for each segment.

Why is it important to specify "at the start of the video in the first frame" in background replacement prompts?

Including this phrase ensures that the new background appears immediately, avoiding a brief flash of the original green or white background at the start of the clip. This results in a more professional, seamless video and saves time in post-production.

Why is generating very long videos directly in VEO 3 not recommended?

Long videos are more likely to run into quality issues, and any mistake or inconsistency means regenerating the entire video, which can be costly in time and resources. Short segments allow for granular control, easier editing, and more engaging storytelling through frequent scene changes.

Which VEO 3 feature is primarily used for this method, and why is "Flow" avoided?

The “Frames to Video” feature is preferred because it works with V3 and supports background replacement and high-quality visuals. The “Flow” feature is avoided since it only works with V2, which lacks sound and produces lower quality output.

What is the critical first step when preparing video clips for assembly in an editor like CapCut?

The first step is to trim the initial frames that display the plain green or white background before the new background appears. This step makes transitions smooth and keeps the video looking professional.

If VEO 3 Fast produces a "tacky" video, what should users try for better quality?

Users should switch to the VEO 3 “Quality” setting and regenerate the segment. Results can vary between “Fast” and “Quality,” so experimenting with both is the best way to achieve optimal visual results.

How does using ChatGPT improve efficiency and consistency in this workflow?

ChatGPT enables you to generate detailed and repeatable character descriptions, action prompts, and background instructions with precision, helping maintain visual consistency and reducing manual effort. For example, creating a batch of prompts for a character in different locations can be automated, ensuring each segment starts with the same character and only the environment changes.

How do I access VEO 3 and start a new project?

To access VEO 3, search for the platform via Google and select the option to “try flow” or “create with flow.” Once inside, choose the “Frames to Video” mode for this method. This ensures compatibility with background replacement and high-quality video segments.

What details should be included in a character description prompt?

Include physical attributes (skin tone, hair, age, gender), clothing style, colors, and any distinguishing features. For example: “A middle-aged Asian man, short black hair, wearing a blue business suit and red tie, standing confidently.” This level of detail ensures the AI generates a consistent character image for each segment.

What is the difference between a mid-shot and a full-body portrait for character images?

A mid-shot frames the character from the waist up, ideal for dialogue or focused interactions, while a full-body portrait captures the entire character from head to toe, suitable for scenes requiring more body language or movement. Choosing the right shot depends on the context of each video segment.

Can I use this method for videos with multiple consistent characters?

Yes. For each character, generate a detailed description and create their image on a plain background. When prompting VEO 3, list each character’s description separately, then detail the actions and interactions in the “Action” section. This allows for multiple consistent characters across scenes.

How can I ensure smooth transitions when changing backgrounds between segments?

Start each segment with the new background appearing instantly by specifying “at the start of the video in the first frame” in your prompt. In editing, use crossfades or quick cuts between scenes and trim any lingering green/white backgrounds for a seamless effect.

What should I do if the character’s appearance changes between video segments?

Double-check that you’re using the exact same character description and the same base image for each segment. Consistency issues often arise from minor prompt or image changes. Always save and reuse the original character image generated on a plain background.

What are some prompt engineering tips for better results in VEO 3?

Be explicit and detailed in your character and action descriptions. Separate the character description from the action. Clearly state background changes, using phrases like “replace the plain green background with…” and specify timing with “at the start of the video in the first frame.” Iterate and refine prompts as you review outputs to improve consistency and quality.

Are there alternatives to CapCut for assembling video segments?

Yes. Any video editing tool that supports basic trimming and sequencing will work, such as Adobe Premiere Pro, DaVinci Resolve, Final Cut Pro, or even free tools like Shotcut. Choose the editor that fits your workflow and comfort level.

How can a business professional use this method for practical video projects?

A business could create a consistent brand spokesperson character for explainer videos, customer onboarding, or product demos. For example, a company launches a training series featuring the same character in different environments: office, factory, and remote work settings, ensuring visual consistency and strong brand identity.

Are there cost implications to generating many short video segments?

Yes, generating multiple short clips can use more credits or resources compared to fewer long generations. However, the ability to catch and correct mistakes early saves money in the long run by avoiding the need to redo entire long videos. Always review and approve each segment before moving on.

How does this method help users in countries with upload restrictions?

By generating character images directly within VEO 3 (instead of uploading), users comply with local regulations and avoid feature restrictions. The green/white background trick allows for full creative flexibility without violating platform rules.

Can I add dialogue or voiceover to my videos using this workflow?

VEO 3 can generate dialogue animations, but for custom voiceovers or complex audio, add your recorded audio during the editing phase in CapCut or another editor. This gives you full control over timing, language, and quality.

Can I create a library of consistent characters for future projects?

Absolutely. Save generated character images (on plain backgrounds) and their detailed descriptions. This makes it quick to produce new videos or update existing ones with the same cast of characters, building a strong visual identity for your brand or series.

Does the complexity of the new background affect video quality?

Yes, highly detailed or dynamic backgrounds may occasionally confuse the AI or create visual artifacts. Start with simple backgrounds and gradually increase complexity, carefully reviewing results for each segment. Adjust prompts as needed for clarity.

How do I prompt for complex character actions or interactions?

Clearly describe the action in the “Action” section, using step-by-step language if needed. For example: “The character waves, then picks up a coffee cup and smiles at the camera.” For multi-character scenes, specify each character’s position and movement.

How can I ensure brand or style consistency across multiple videos?

Use the same character description, outfit, and color palette in every prompt. Maintain consistent camera angles (mid-shot or full-body), and design backgrounds that reflect your brand’s visual identity. Document your prompt templates for future reference.

Is this workflow scalable for larger projects or series?

Yes, especially with prompt templates and character libraries. You can create entire video series by reusing descriptions and automating prompt generation with ChatGPT, ensuring consistent results across dozens of segments or episodes.

What can I do if the background doesn’t replace correctly in some segments?

Check your prompt for clear instructions, such as “replace the plain green background in the uploaded image with [background] at the start of the video in the first frame.” If issues persist, try simplifying the background description or regenerating the segment.

What export formats are supported by VEO 3 and video editors?

VEO 3 typically exports in standard video formats like MP4. Most video editors support a wide range of formats, so you can convert or export your final video in the format best suited to your distribution platform (YouTube, LinkedIn, internal LMS, etc.).

Can you provide an example of a complete prompt for generating a video segment?

Character Description: “A young Indian woman with shoulder-length black hair, wearing a yellow blouse and black slacks, smiling.”
Action: “The character walks into a modern office and greets colleagues.”
Background Replacement: “Replace the plain green background in the uploaded image with a modern open-plan office at the start of the video in the first frame.”

Are there minimum hardware requirements for this workflow?

VEO 3 is cloud-based, so even basic laptops or tablets can run the workflow. For editing, a computer with at least 8GB of RAM and a modern processor is recommended for smooth video playback and export, but most editing tools will run on standard business hardware.
