Create Thumbnails Around the Story

Keep the subject, audience, and viewing context connected from the first brief to the final cover.

Video Brief

Find the Hook Before Choosing the Layout

Tell the AI thumbnail generator what the video actually delivers and who should watch it. MiniMax Code can help turn that premise into a focused image brief: one subject, a recognizable action, and a short headline. Keep the promise accurate. A tutorial cover should show what viewers will learn, while a review should not imply a verdict the video never makes.

Creative Variations

Compare Different Ideas, Not Just Colors

Try a product close-up, an environmental scene, or a graphic treatment while keeping the video topic fixed. Ask for specific revisions to subject scale, negative space, contrast, and headline placement. Comparing meaningfully different directions is more useful than collecting many nearly identical covers. Generated lettering and details still need inspection.

Feed Readiness

Check the Small-Screen View

Review the chosen cover at its expected feed size, not only full screen. Make sure the subject is recognizable, the words are legible, and the duration badge will not cover critical content. Match the thumbnail to the title without repeating every word. Resize or refine the final file in your chosen workflow and check the publishing platform requirements.
