LosslessCut
GUI tool for lossless trimming / cutting of videos using ffmpeg. Great for rough processing of large video files taken from a video camera, drone, etc. Lets you quickly get rid of the useless parts. It doesn't do any decoding / encoding and is therefore very fast and has no quality loss. Also allows for taking JPEG snapshots of the video at the selected time.
Download
Installing / running
- Install ffmpeg
- Download latest LosslessCut from releases
- Run app
- If ffmpeg is available in $PATH/%PATH% it will just work
- If not, a dialog will pop up to select ffmpeg executable path.
Documentation
Drag drop a video file into player to load or use ⌘/CTRL+O. Select the start and end time and press the scissors button. The original video files will not be modified. Instead it creates a lossless export in the same directory as the original file. Preserves exif data.
