Getting Ensuring Character Consistency Across Generations right takes more than a single prompt. This 4-stage guide covers Diagnose the Wall, Isolate and Fix, Verify the Resolution, and more, breaking the whole process into focused steps where each prompt builds on the last. Inconsistent appearances of the same character can disrupt the narrative flow of your video. This inconsistency can lead to confusion for viewers and undermine the overall quality of your project. By using these prompts and techniques, you can achieve a cohesive look for your characters across multiple generations. Every prompt is optimized and runs in ChatGPT, Claude, and Gemini.

Diagnose the Wall

Start by identifying the root cause of the inconsistency in character appearance. This involves testing various aspects of your prompts and settings to isolate the issue.

Test Core Subject

Run a baseline test prompt using only the core subject: '[YOUR CHARACTER DESCRIPTION]'. Analyze the results to determine if the character's appearance remains consistent and identify any specific elements that may cause variation in the portrayal. Provide a summary of your findings and suggest adjustments if inconsistencies are found.

Diagnose the Wall

Use Reference Prompt

Test the following reference prompt that has produced consistent results in the past: '[REFERENCE CHARACTER PROMPT]'. Analyze the output generated by this prompt and compare it to the results from your current prompt to determine if the inconsistency is due to the prompt itself or the model's performance.

Diagnose the Wall

Change One Parameter

Change one parameter in your prompt to test for consistency. For example, use '[YOUR CHARACTER DESCRIPTION] in [NEW MODEL VERSION]' and analyze how this modification impacts the character's portrayal. Document any differences in consistency and provide insights on the effectiveness of the new model version.

Diagnose the Wall

Generate Variations

Generate four variations based on the prompt '[YOUR CHARACTER DESCRIPTION]'. For each variation, highlight the differences in character traits and consistency, and provide a brief analysis of how each variation aligns with the original description.

Diagnose the Wall

Compare Against Reference

Compare the generated output of your character to a reference image or description. Provide the character description as [YOUR CHARACTER DESCRIPTION] and the reference image as [REFERENCE IMAGE]. Identify specific areas where the output differs from the reference, and suggest improvements to align the character more closely with the original concept.

Diagnose the Wall

Isolate and Fix

Once you've diagnosed the issue, apply specific techniques to correct the inconsistencies in character appearance.

Add Specific Descriptors

Rephrase the descriptor in your prompt to provide a detailed and specific description of the character's appearance. Include features such as hair color, eye color, clothing style, and any distinguishing marks or traits to ensure a consistent representation. For example, use '[YOUR CHARACTER DESCRIPTION, INCLUDING SPECIFIC FEATURES LIKE HAIR COLOR, CLOTHING, ETC.]'.

Isolate and Fix

Include Negative Prompts

Generate a video of [YOUR CHARACTER DESCRIPTION], ensuring to avoid the inclusion of [UNWANTED ELEMENTS]. Explain how these negative prompts can help the model concentrate on achieving the desired appearance and provide examples of effective negative prompts for different scenarios.

Isolate and Fix

Change Model Version

Switch to a different model version to improve character consistency. Provide the character description as '[YOUR CHARACTER DESCRIPTION]' and specify the new model version as '[NEW MODEL VERSION]'. Analyze the output and determine if the change has led to better results in maintaining character traits.

Isolate and Fix

Restructure Prompt Order

Restructure the prompt order for character descriptions by placing the subject first and the style last. For example, format it as '[YOUR CHARACTER DESCRIPTION], [STYLE]. Explain how this adjustment can help the model prioritize the character's appearance and provide an example to illustrate the change.

Isolate and Fix

Lock the Seed

Lock the seed to ensure consistent results across generations. Generate a video of [YOUR CHARACTER DESCRIPTION] using the seed value [YOUR SEED]. Explain how this seed impacts the uniformity of the generated content and provide examples of variations that may occur without it.

Isolate and Fix

Verify the Resolution

After applying fixes, confirm that the changes have resolved the inconsistency issue.

Generate New Variations

Generate 4 new variations based on the updated prompt: '[YOUR CHARACTER DESCRIPTION]'. After generating these variations, compare them to identify any inconsistencies in character traits, behaviors, or backgrounds, and summarize your findings.

Verify the Resolution

Compare Against Baseline

Compare the new outputs of [YOUR CHARACTER DESCRIPTION] against the Stage 1 baseline. Identify any inconsistencies in character portrayal, detailing specific differences in appearance, behavior, or dialogue that deviate from the baseline. Provide suggestions for adjustments to align the new outputs more closely with the established baseline.

Verify the Resolution

Test Harder Version

Test the model's consistency by providing a harder version of the subject. Use the following scenario: '[YOUR CHARACTER DESCRIPTION] facing a challenging situation where they must make a difficult decision. Analyze how the character's traits influence their choices and whether they remain consistent with their established personality.

Verify the Resolution

Lock Seed for Consistency

Generate a video of [YOUR CHARACTER DESCRIPTION] using the locked seed [YOUR SEED]. Verify whether the output is consistent with previous generations and analyze any differences in character portrayal or quality.

Verify the Resolution

Check Different Aspect Ratio

Generate a video of [YOUR CHARACTER DESCRIPTION] in a 16:9 aspect ratio. Verify if the character's consistency holds across this aspect ratio by comparing it to previous outputs. Note any differences in appearance or behavior that may indicate an aspect-ratio dependency in the character's representation.

Verify the Resolution

Prevent Recurrence

To avoid future inconsistencies, create reusable templates and workflows that ensure character appearance remains stable.

Base Prompt Template

Create a character consistency template for VEO that includes the following elements: '[YOUR CHARACTER DESCRIPTION, INCLUDING SPECIFIC FEATURES]' and '[STYLE]'. Ensure that this template is reusable by modifying only the character description for future generations while maintaining the established style.

Prevent Recurrence

Negative Prompt Bank

Create a negative prompt bank that lists common unwanted elements to avoid when generating [YOUR CHARACTER]. Include at least five specific examples of these unwanted elements, and explain why each should be avoided to ensure consistency in character development.

Prevent Recurrence

Seed-Locking Workflow

Establish a seed-locking workflow by locking the seed to [YOUR SEED] for every generation. Explain how this practice will help maintain consistency and uniformity across outputs, and provide specific steps to implement this workflow effectively.

Prevent Recurrence

Style-Consistency Checklist

Develop a style-consistency checklist for maintaining the appearance of [YOUR CHARACTER]. Include specific elements such as [SPECIFIC ELEMENTS] that must be present in every prompt to ensure consistency in style and presentation.

Prevent Recurrence

Parameter Combination Template

Create a parameter combination template for generating consistent character results. Specify the use of [MODEL VERSION], apply the style of [STYLE], and lock the seed to [YOUR SEED] when generating [YOUR CHARACTER]. Ensure that this template is saved for future reference to maintain consistency in your outputs.

Prevent Recurrence

Frequently asked questions

Why does my character look different in each video?+

Inconsistencies often arise from vague descriptors in your prompts. To fix this, ensure your character description includes specific features like hair color and clothing style.

How can I ensure my character maintains the same look?+

Use a consistent seed across generations and include detailed descriptions in your prompts. This helps the model generate similar appearances.

What should I do if the background changes too?+

Background inconsistencies can be addressed by specifying the environment in your prompt. Include details like 'in a forest' or 'in a city' to stabilize the background.

Can I use reference images for consistency?+

Yes, using reference images can help guide the model. Include a prompt like 'Generate a video of [YOUR CHARACTER] based on [REFERENCE IMAGE].' This can improve consistency.

What if my character still looks different after these fixes?+

If issues persist, consider testing with different model versions or restructuring your prompt order. This can sometimes yield better consistency results.
