Turn any video into Scratch costumes
FrameScratch splits a clip into frame-by-frame images, packages them for Scratch's costume importer, and shows you the exact blocks to animate it.
Start extracting framesWhat you get
Private by design
Your video never leaves your device. Extraction happens locally with the browser's video and canvas APIs.
Trim before you extract
Set a start and end point so you only extract the part of the clip you actually need.
Control size & format
Choose PNG or compressed JPEG, and scale resolution down to keep your costume pack lightweight.
Ready-made blocks
We calculate the exact wait time for your chosen frame rate and show you the block stack to paste into Scratch.
