One frame, every few seconds
Need a frame every few seconds instead of by shot? Interval Capture grabs one frame at a fixed pace you choose, and runs entirely in your browser.

It loads locally in your browser. The video is never uploaded to a server.
Pick any interval with the slider, and see an estimate of how many frames you will get.
Frames are captured on the spot and exported as a ZIP, contact sheet, GIF, or palette.
Upload a video and see it work. Preview is free before you sign up.
