Designing Roblox video covers
Describe the scene, character, and style you want on the cover, then generate and review a few options.
Input Constraints
- Describe the scene, characters, and focal point you want
- Keep the aspect and composition in mind for a video thumbnail
- Avoid text or logos in the prompt unless you plan to add them later
- Review the result for odd limbs, distorted objects, or wrong colors
Practical Tips
- Name a style word like 'neon', 'cinematic', or 'cartoon'
- Mention the focal point first so it stays the center of the image
- Try a few variations of the same scene before choosing
- Keep colors high contrast so the cover reads at small size
Privacy
- Do not upload personal or sensitive material unless you have permission to use it.
Usage Rights
- Confirm that you have the rights needed for the inputs and intended use of the result.

Limitations to know before generating
- Generated Roblox-style characters may not match exact avatar details or accessories from the actual game.
- Complex multi-character scenes or detailed builds are harder to control and may include visual errors.
- The tool does not pull actual Roblox game assets; results are artistic interpretations based on your description.
- Thumbnail effectiveness depends on title and niche; a strong image alone does not guarantee views.
- Results vary with prompt clarity; vague scene descriptions often produce generic or unfocused covers.
