About Short Frame Check
Short Frame Check is made and operated by Short Frame Check. It helps video creators preview a YouTube Shorts safe zone guide on a local image or video frame.
Adjust margins, opacity and an optional caption reference, then download a PNG preview or transparent overlay. Video exports save a single frame. Files are processed in your browser.
The default guide follows Google’s vertical video advertising reference. It is not an official YouTube tool, and organic Shorts interfaces can differ by device and viewing state. It does not automatically detect or move subtitles.
