Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work. Or you can add a music or subtitle track to your video without needing to encode. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files.The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. Position must be a time duration specification, see (ffmpeg-utils)the Time duration section in the ffmpeg-utils(1) manual.LosslessCut The swiss army knife of lossless video/audio editing When used as an output option (before an output url), decodes but discards input until the timestamps reach position. When doing stream copy or when -noaccurate_seek is used, it will be preserved. When transcoding and -accurate_seek is enabled (the default), this extra segment between the seek point and position will be decoded and discarded. Note that in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. When used as an input option (before -i ), seeks in this input file to position. So what about this 'decoding up until the point' if I put them after -i? How is it beneficial to decode what it's going to discard? It doesn't affect the quality of the stream copy, correct? What do the docs mean below when it says 'When doing stream copy or when -noaccurate_seek is used, it will be preserved'? What is being preserved? So, according to the below excerpt from ffmpeg's docs, putting them before -i will cause it to seek directly to the closest key frame. I'm coming back to this again because I don't quite understand the significance of putting -ss and -t before or after -i.
