LosslessCut: “The swiss army knife of lossless video/audio editing”
Today in the treasure-trove that is the Hacker News comment section, I learned about LosslessCut. Self-described as, "The swiss army knife of lossless video/audio editing", I was intrigued. It's a GUI for FFmpeg, specializing in… you guessed it: lossless cutting!
I use FFmpeg fairly often from the command line and am versed in the practice of using -c:v copy -c:a copy or even -c copy to achieve cutting without having to re-encode, which makes for very fast results. My usual use-cases involve extracting a small portion from an audio or video file, using -ss (start time) and -t (duration) as prefixes in my ffmpeg command.
Anything beyond that would have me turn to DaVinci Resolve — an excellent video editing application. In situations where I wouldn't also be adjusting audio or color grading, LosslessCut offers a lot of value.
I tested it with a sample video from my iPhone, and it worked seamlessly!
