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. 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. Only scans up to 60 seconds to find a keyframe.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. You can still probably do multi-passes and then recreate a file with all the streams. All other video streams have to be disabled (in the tracks panel). Only supports cutting a single video stream. I've had success with some h264 files, and only a few h265 files seem to work. This experimental feature will re-encode the part of the video from the cutpoint until the next keyframe in order to attempt to make a 100% accurate cut while losslessly copying the rest of the segment. Have now made an initial implementation of this. They know there are issues and are actively working on it. The SmartEdit feature in LosslessCut is in experimental stage. LosslessCut is perfectly capable of doing keyframe cuts, I don't really need an alternative for that. Thanks for the recommendations but they don't really help me. Authoring works and SR are (more or less) slightly budget versions of Mastering Works since MW can do everything those programs can do and more Now the slightly possible better news for you is that Tmpg's Master Works should do this as well as output to the type of file that you require. It allows you to add clips to the end of a track so when the disc is made it shows as one clip rather than several and the test I tried kept the subtitles with a 14 second edit and a 26 second edit as one clip The catch in that software of course is the output being either dvd or bluray format. However Authoring Works does not do this and you can edit while keeping them. You are correct in that SR ditches subtitles. Is there another, better solution to this problem? I was curious about this since I have both TMPG Authoring Works 6 as well as their Smart Render program. That makes the usually simple process of "cut, rename new file, done" pretty tedious. That means I'm forced to demux them with ffmpeg, sync them with SubtitleEdit, and mux them again. TMPGEnc SR does not have that problem but removes every subtitle from the cut video. That is not at all what I'm looking for, I want the cut to be as lossless as possible. I've tried both TMPGEnc SR and VideoReDo and both have problems: VideoReDo simply does not support 10-bit videos and reencodes them to 8-bit. The former obviously have a lot of limitation on where you can successfully cut and the SmartEdit feature in LosslessCut doesn't really work. Following advice from this forum I've tried LosslessCut/SolveigMM which both mostly rely on keyframes and more advanced software like TMPGEnc Smart Renderer or VideoReDo which use keyframes when possible and reencode whenever it's not.
