Example setup: a yellow smiley stays in the upper right corner of a short room shot. The wall is largely plain, and no person crosses the area.
Prepare a representative clip
In your editor, trim one continuous shot around the sticker’s full appearance. Start with about 2 to 3 seconds if that includes the difficult moment; avoid a clip shorter than 2 seconds. If you have only trial credits, inspect the quoted duration before submitting so the selected portion includes the sticker.
Upload and choose object mode
Use an MP4 or MOV, up to 100 MB, 1080p and 60 fps, with a constant frame rate. The upload tool starts in object mode. Text mode is intended for visible words and is not the choice for a graphic emoji. Keep original audio enabled if the scene needs its sound.
Describe the graphic, not the wall
Try: “Remove the yellow smiley emoji fixed in the upper right corner.” Replace color and position with what is actually visible. Avoid “remove everything” or descriptions of the underlying subject. These prompt examples are suggestions, not tested presets.
Compare the same frames
Play the full result, then pause at the first, middle, and last affected frames. Check the wall’s brightness, its texture, any corner lines, and the frame just after the emoji disappears. Reject a pulsing patch even if one paused frame looks acceptable.
