I made a script to do this a while back for cutting intros off of videos. https://gist.github.com/iwalton3/c034ec5a942466206fbee859184b625d https://gist.github.com/iwalton3/c034ec5a942466206fbee859184... The notable function that does video cuts without a full re-encode is shortenVideo, which cuts a certain number of seconds off the beginning of a video. I've never had any issues with it, but I only used it on h264 mp4 files.
