- What happens
- The picture is resized and saved in the format that was opened. 1080p, 720p, and 480p set the shorter side, so vertical videos stay vertical, and only sizes smaller than the video are offered. Setting both width and height fits the picture inside that box.
- Limits
- A video track is required. Browser codec support and device memory affect export.

The picture fits inside that box without stretching.
Only sizes smaller than your video are offered, because making a video bigger adds no detail. A 720p video can become 480p, or any size you enter.
