Developer: Jiulong Zhao
Genres: Photo & Video

Specially designed for UHD 4K, 5K, 8K videos!

Drag & drop your movie, preCut Pro will extract EACH video frame and save them into images at the highest possible resolution.

Still, using snapshot or screen-capture on obtaining a single frame image of a movie? Tired of fast-forwarding, rewinding, and rewinding some more, but still cannot find the best frame you want? Then preCut is just the app you need.
