Turn the title into one visual promise
Write down the single idea a viewer should understand at a glance. Describe the subject, expression and setting around that idea, and leave space for the title instead of filling every corner with detail.
A thumbnail has one job: make the right viewer stop and understand the promise. DomoAI can generate cover directions from a title, a portrait or a frame from the video, so you can compare compositions before spending time in a design tool.

Every DomoAI workflow starts from a prompt and an optional reference file. Nothing has to be rebuilt by hand.
Write down the single idea a viewer should understand at a glance. Describe the subject, expression and setting around that idea, and leave space for the title instead of filling every corner with detail.
Explore a close-up reaction, a two-subject standoff and a clean object-led frame. Keep the background simple and the emotion readable at small size. Use a real photo when the creator needs to remain recognisable.
Choose the strongest visual, add the final title in a design editor and check it at phone size. Export the standard widescreen cover plus any alternate crops required by your publishing workflow.
DomoAI workflows differ by the material you already have. Pick the one that matches it.
| Workflow | What you provide | Good for |
|---|---|---|
| Prompt to thumbnail | A title, concept and visual description | Fast early cover directions |
| Photo to thumbnail | A creator or product photo | Keeping a recognisable face or product |
| Video still to thumbnail | A frame from the finished video | A cover that matches the actual content |
| Image editor | A generated or uploaded image | Adding the exact title, logo and arrows |
Answers about inputs, limits, resolution, and how credits are used.
Short words sometimes render, but generated text is unreliable. Use the model for the image and add the final title in a design editor so spelling, font and spacing are exact.
The standard cover is a 16:9 image, commonly exported at 1280 by 720 pixels. Check the current upload requirements in YouTube Studio and keep important details away from the duration badge in the corner.
Yes. A clear portrait with a strong expression and simple background usually works better than a wide group photo. Only use images of people you have permission to depict.
Most viewers see the cover at a small size. Test the face, main object and title on a phone; if the idea is unclear in two seconds, simplify the frame before publishing.
