20 of the best prompts for adjusting aspect ratio for VEO, step by step across 4 stages. Works with ChatGPT, Claude, and Gemini.
The tool outputs video dimensions that do not match the specified format, leading to frustration. This inconsistency can disrupt the creator's workflow, especially when preparing content for specific platforms. These prompts and techniques will help ensure that the generated videos meet the required aspect ratio for any intended use. This guide walks you through every stage of Adjusting Aspect Ratio for VEO, from Diagnose the Wall all the way through Prevent Recurrence, with a curated, copy-ready prompt at each step. Each stage targets a specific phase of the process so you always know exactly what to ask and what output to expect. Works with ChatGPT, Claude, and Gemini and any other major AI tool.
Start by identifying the current output aspect ratio and how it deviates from your target. This will help you understand what adjustments are needed.
Test Core Subject
Run a baseline test prompt using only the core subject: '[PLACEHOLDER]'. Analyze the output to determine if the aspect ratio issue arises from the subject itself or if it is influenced by other elements in your prompt. Provide a summary of your findings and any recommendations for adjustments.
Use Reference Prompt
Test the following known-working reference prompt that has the correct aspect ratio: '[REFERENCE PROMPT]'. Analyze the output generated by this reference prompt and compare it to the output from your specific prompt to determine if the issue is related to your prompt or the tool's settings.
Change One Parameter
Diagnose the wall issue related to the wrong aspect ratio by changing one parameter in your settings. Specifically, adjust the model version to the latest available and observe if this resolves the unexpected aspect ratio problems you are experiencing.
Generate Variations
Generate four variations of the prompt '[PLACEHOLDER]'. Ensure that each variation explores different aspects of the content while maintaining the same core theme, and analyze whether the aspect ratio differs in the outputs.
Compare Against Reference
Compare the output image to the reference image or description that has the correct aspect ratio. Identify any specific discrepancies in dimensions or framing, and provide a detailed explanation of how these differences impact the overall visual quality.
Now that you have diagnosed the issue, apply specific fixes to ensure the correct aspect ratio is achieved.
Specify Aspect Ratio
Specify the desired aspect ratio for the generated video. Choose a format from the dropdown, such as 16:9 for landscape or 4:3 for standard, and confirm that the output video adheres to this specification.
Rephrase Prompt Elements
Rephrase the following prompt to explicitly include the desired aspect ratio. For example, you could say, "Create a cinematic video of [PLACEHOLDER] in a 16:9 format." Ensure that the new prompt clearly communicates the aspect ratio requirement to guide the generation process effectively.
Add Negative Elements
Incorporate negative prompt elements to exclude unwanted aspect ratios in your output. For example, specify "Exclude any square formats" and "Avoid any portrait orientations." This will help refine the generated content to match your desired dimensions more effectively.
Change Style Mode
Switch to a different style mode that is known to produce outputs with the correct aspect ratio. Explain how this style mode affects the output and provide specific examples of scenarios where it has successfully resolved similar issues.
Restructure Prompt Order
Restructure the prompt order by placing the subject first and the style last. For example, use the format '[SUBJECT], cinematic style.' Explain how this adjustment can help the tool prioritize the correct aspect ratio for better results.
Confirm that the adjustments made have resolved the aspect ratio issue effectively.
Generate New Variations
Generate 4 new variations of the adjusted prompt, '[PLACEHOLDER]'. For each variation, verify that it adheres to the specified aspect ratio and provide a brief explanation of how each one meets the requirement.
Compare to Baseline
Compare the new outputs from the veo-wrong-aspect-ratio use-case against the Stage 1 baseline. Verify whether the aspect ratio has improved by checking the dimensions for consistency across all outputs, and provide a detailed analysis of any discrepancies found.
Test Harder Subject
Run a test using a more complex version of your subject, such as '[COMPLEX PLACEHOLDER]'. Ensure that the aspect ratio is maintained throughout the test and provide a detailed analysis of any discrepancies observed during the process.
Lock Seed for Consistency
Run the generation process with a locked seed to ensure that the results remain consistent across multiple attempts. Verify that the aspect ratio remains stable by comparing the outputs from each attempt and noting any discrepancies.
Check Different Aspect Ratio
Check the output generated by the tool at a different aspect ratio, specifically 1:1. Evaluate whether the content maintains its quality and clarity in this format, and provide feedback on any issues encountered during the adaptation process.
Establish templates and workflows to avoid future aspect ratio issues.
Base Prompt Template
Create a cinematic video using the following template: '[PLACEHOLDER], cinematic style, aspect ratio 16:9'. Ensure that the content in the [PLACEHOLDER] is tailored to the specific theme or subject of the video, and maintain the cinematic style throughout the production.
Aspect Ratio Parameter Bank
Create a bank of aspect ratio parameters that includes common ratios such as '16:9', '1:1', and '9:16'. Ensure that this bank can be easily referenced when setting up new prompts to maintain consistency in aspect ratio usage across projects.
Negative Prompt Bank
Create a negative prompt bank that includes specific phrases to avoid certain formats, such as 'Exclude square formats' and 'Avoid 4:3 ratios'. Ensure that this bank is comprehensive and can be used to refine prompts consistently across various projects.
Seed-Locking Workflow
Establish a workflow that locks the seed after achieving a desired output to ensure consistency in aspect ratio across multiple generations. Describe the specific steps involved in this workflow, including how to monitor and verify the aspect ratio during each generation process.
Style-Consistency Checklist
Create a detailed checklist for maintaining style consistency in design projects. Include specific steps for verifying aspect ratio settings before each generation, and outline additional factors to consider, such as color schemes, typography, and layout alignment. Ensure the checklist is comprehensive enough to prevent future issues related to style inconsistencies.
This issue often arises from not setting the aspect ratio in the dropdown before generating the video. Always ensure you select the correct aspect ratio in the settings before entering your prompt.
To maintain correct dimensions, always use a base prompt template that specifies the aspect ratio. Additionally, utilize negative prompts to exclude unwanted formats.
If the video still doesn't match, try restructuring your prompt order or changing the style mode. These adjustments can help the tool better understand your requirements.
Yes, you can create a reusable template that includes your desired aspect ratio. Save this template and use it as a starting point for future projects to ensure consistency.
You can set up a workflow that includes generating variations at different aspect ratios. This allows you to quickly compare outputs and find the best fit for your needs.
