Thumbnail editor
A thumbnail decides whether the video gets opened. FrameOS lets you pull the right frame from your footage and shape it into a thumbnail — crop it, add bold text, and adjust it — instead of settling for whatever auto-frame the platform grabs.
Start from the right frame
Scrub your video and pull the exact moment that sells the click — a reaction, a peak, a clear face — rather than the arbitrary frame a platform picks.
Add text that reads at thumbnail size
Put a few bold words on it, sized to be legible in a crowded grid, so the thumbnail says what the video delivers.
Crop and frame for the platform
Adjust the crop and composition so the subject lands where it should at YouTube and Shorts thumbnail sizes.
From the same footage you clipped
Because the thumbnail comes from the video you're already editing in FrameOS, you don't jump to a separate design tool to make it.

FAQ
Can I edit a thumbnail in FrameOS?
Yes. Pull a frame from your video, then crop it, add text, and adjust it into a thumbnail that earns the click.
Can I use any frame from the video?
Yes — scrub to the exact moment you want and use that as the basis for the thumbnail.
Do I need a separate design tool?
No — the thumbnail is built from the footage you're already editing, so you stay in one place.
