LosslessCut 🎥

Simple, cross platform video editor for lossless trimming / cutting of videos. Great for rough processing of large video files taken from a video camera, GoPro, drone, etc. Lets you quickly extract the good parts from your videos. It doesn't do any decoding / encoding and is therefore extremely fast and has no quality loss. Also allows for taking JPEG snapshots of the video at the selected time. This app uses the awesome ffmpeg🙏 for doing the grunt work. ffmpeg is not included and must be installed separately.

Download

Documentation

Drag drop a video file into player to load or use ⌘/CTRL+O.
Select the start and end time
Press the scissors button to export a slice.
Press the camera button to take a snapshot.

The original video files will not be modified. Instead it creates a lossless export in the same directory as the original file with from/to timestamps. Note that the cut is currently not precise around the cutpoints, so video before/after the nearest keyframe will be lost. EXIF data is preserved.
