When the output dimensions do not match the specified format, it can lead to frustration and wasted effort. This inconsistency can disrupt your video production workflow and affect the final presentation. By following these prompts and techniques, you can ensure your videos are generated in the correct aspect ratio for your intended platform. Built across 4 distinct stages covering Diagnose the Wall, Isolate and Fix, Verify the Resolution and more, this guide gives you one expert prompt per step so you never have to write from scratch or guess what the AI needs. The prompts work in ChatGPT, Claude, and Gemini and are designed to get usable output on the first try.
Start by identifying the source of the aspect ratio issue. Testing various parameters will help you pinpoint the cause.
Test Core Subject
Run a baseline test using only the core subject: '[PLACEHOLDER]'. Analyze the output to determine if the aspect ratio issue is caused by the subject itself or if it stems from other parameters in the configuration. Provide a summary of your findings and any recommendations for adjustments.
Use Reference Prompt
Test the following reference prompt to determine if the issue is related to your specific prompt or the tool's settings: '[REFERENCE PROMPT]'. Analyze the output generated by this prompt and compare it to the expected results to identify discrepancies in aspect ratio.
Change One Parameter
Diagnose the aspect ratio mismatch by adjusting one parameter in the prompt. Change the style setting to '[NEW STYLE]' and observe if this adjustment resolves the issue. Provide a detailed analysis of the results and any further recommendations based on your findings.
Generate Variations
Generate four variations of the prompt using '[PLACEHOLDER]' as the subject. Analyze the output dimensions for each variation to identify any differences in aspect ratio consistency.
Compare Against Reference
Compare the generated video output against the reference image or description to identify specific discrepancies in aspect ratio. Provide a detailed analysis of how the aspect ratio of the generated video deviates from the known correct output, and quantify the differences in percentage or ratio format.
Once you have diagnosed the issue, apply specific techniques to correct the aspect ratio.
Set Aspect Ratio Dropdown
Set the aspect ratio dropdown to '[TARGET RATIO]' (for example, 16:9 for landscape) in the new generation settings. Confirm that the output format aligns with this selected aspect ratio to ensure optimal results for your project.
Rephrase Prompt
Rephrase the following prompt to include a specific aspect ratio indication. For example, you could say, "Create a video of [PLACEHOLDER] in a 16:9 format." Ensure that the aspect ratio is clearly defined to help the AI understand your requirements more effectively.
Add Negative Prompts
Add negative prompt elements such as 'not square' and 'avoid 1:1 ratio' to guide the AI away from producing undesired formats. Specify the desired aspect ratios you want to achieve and explain how these negative prompts will help refine the output dimensions effectively.
Change Model Version
Switch to a different model version that is optimized for handling aspect ratios. Review the available model versions in the settings and select one that is specifically known for producing better output consistency in aspect ratio handling.
Restructure Prompt Order
Restructure the order of your prompt by placing the subject at the beginning and the style at the end. For example, format it as '[PLACEHOLDER], in the style of [STYLE]'. Explain how this change improves clarity and focus for the AI in generating responses.
After applying fixes, run tests to confirm that the aspect ratio issue has been resolved.
Generate New Variations
Generate four new variations of the adjusted prompt that confirm the aspect ratio is now correct. Ensure that each variation maintains the same subject and settings for consistency, and provide a brief explanation of how each variation addresses the aspect ratio issue.
Compare Against Baseline
Compare the new output to the Stage 1 baseline to determine if the aspect ratio has improved. Specifically, assess whether the output aligns with the specified format of [SPECIFIED FORMAT] and provide a detailed explanation of any discrepancies observed.
Test Harder Subject
Run a test using a more complex subject to evaluate if the aspect ratio remains consistent under varying conditions. Use '[HARDER SUBJECT]' as the input to challenge the tool and provide a detailed analysis of the results, including any discrepancies observed.
Lock Seed for Consistency
Generate outputs using a locked seed to ensure consistency across all results. After generating, verify that the aspect ratio remains stable and document any discrepancies you observe.
Check Different Aspect Ratios
Check how the tool adapts to different aspect ratios by testing the same prompt at 1:1 and 4:3. Analyze the outputs for each ratio, noting any differences in composition, clarity, and overall effectiveness in conveying the intended message.
Establish reusable templates and workflows to avoid future aspect ratio issues.
Base Prompt Template
Adjust the aspect ratio of the following content: '[PLACEHOLDER]' to the specified format of [TARGET RATIO]. Ensure that the adjustments maintain the visual integrity and clarity of the content while adhering to the new aspect ratio guidelines.
Aspect Ratio Parameter Combination
Save the following parameter combination to ensure a consistent aspect ratio in your projects. Set the aspect ratio to '[TARGET RATIO]' and apply the style '[STYLE]'. Explain how this combination improves your workflow and detail any potential issues that may arise if these parameters are not used.
Negative Prompt Bank
Create a negative prompt bank that includes phrases such as 'not square' and 'avoid 1:1 ratio'. Ensure that this bank contains at least ten distinct phrases that can be used to guide the AI in generating content with the correct aspect ratio. Provide examples of how each phrase can be effectively integrated into prompts for clarity.
Seed-Locking Workflow
Implement a seed-locking workflow for video generation. Ensure that the seed is locked each time a video is created to maintain consistency in the outputs. Provide a step-by-step guide on how to implement this process effectively.
Style-Consistency Checklist
Create a style-consistency checklist for new projects that includes the following elements: aspect ratio settings, prompt structure guidelines, and a list of effective negative prompts. Ensure that each item on the checklist is clearly defined and actionable to maintain consistency across all projects.
The aspect ratio mismatch often occurs due to incorrect settings in the Seedance interface. Ensure you set the aspect ratio dropdown correctly before generating videos.
To maintain the correct format, always start with a base prompt template that includes your desired aspect ratio. Adjust the subject as needed while keeping the format consistent.
If the aspect ratio keeps changing, check for any conflicting parameters in your prompt. Use negative prompts to specify unwanted ratios and lock the seed for consistency.
Yes, you can create multiple templates for different platforms by adjusting the aspect ratio in your base prompt. Save these templates for quick access.
To compare your output against a reference, generate a video using your prompt and then visually inspect it against a known correct output. Look for discrepancies in dimensions.
