The program obviously has to round the actual cut point to a frame boundary, but you have zero control over that and instead are forced to juggle about with random 16.66666~ms steps counting from the last random point you managed to land on by clicking on the position bar. The part where you can't directly specify cutpoints despite the program giving you the position down to miliseconds and you have to accept random granularity that has no basis on the underlying file just bothers me. The main problem is the lack of any visual cue about the content of the file. Quote from: j7n on 00:23:26 Isn't 60 fps enough granularity given that audio formats offer 38-46 fps? Resuming, I'm looking for a good lossless cutter for these formats, hopefuly one that will approach the quality of mp3DirectCut. You have to use the positionbar and the framestep buttons for everything. Specially aggravating is the fact that you are given a milisecond based timestamp but you can't manually edit those.
I assume that, with a video file, it will maintain frame boundary alignment, but I'm not editing video. Interestingly, if you click in the positionbar, you may reach a postion that's not aligned to these imaginary frame boundaries, and if you use the framestep buttons from that non-aligned position, it advances the equivalent of 1 frame from that position. When fed with audio-only, it seems to assume a 60Hz framerate judging by to the rounded up 0.016666~ second steps that it allows. The GUI is really meant for video, and, while, being based on FFmpeg, it also supports audio-only files, the position granularity seems to be meant for framesteps, which is not too good for audio. The problem is that the interface is terrible for cutting audio. So far I've been using LosslessCut, which does the job, at least in the technical aspect: That is, it cuts the file correctly as far as I can tell. MP3 is well covered by the excelent mp3DirectCut, which marks the standard I'm after, with it's nice visual editor. Overall, LosslessCut is an excellent tool for anyone looking to perform lossless operations on their video and audio files quickly and efficiently.I'm looking for a good lossless cutter with suppor for the popular lossy audio codecs, mainly Opus, Vorbis, and AAC. You can also edit file metadata and per-stream metadata and cut with chapter marks. LosslessCut allows you to import segments from various sources, such as MP4/MKV chapters, text files, YouTube, CSV, CUE, and XML (DaVinci, Final Cut Pro). You can give labels to cut segments, view segment details, and export/import cut segments as CSV. Other features include the ability to save per-project cut segments to a project file, view FFmpeg last command log, and undo/redo. It also includes timeline zoom and frame/keyframe jumping for accurate cutting around keyframes.
You can apply a per-file timecode offset, change rotation/orientation metadata in videos, and view technical data about all streams.

LosslessCut lets you take full-resolution snapshots from videos in JPEG/PNG format and provides manual input of cutpoint times.
You can also extract all tracks from a file and remux them into any compatible output format. LosslessCut offers a wide range of features, including lossless cutting of most video and audio formats, lossless rearrangement of the order of video/audio segments, lossless merge/concatenation of arbitrary files with identical codec parameters, and lossless stream editing, allowing you to combine arbitrary tracks from multiple files. This is accomplished by an almost direct data copy using the powerful FFmpeg technology, which performs all the grunt work behind the scenes.Īs a result, all of the operations you perform with LosslessCut are exceptionally fast and efficient. With LosslessCut, you can also add music or subtitle tracks to your video without needing to encode the entire file. This allows you to extract the desired parts of your videos quickly without losing quality or having to perform a slow re-encode process. Its primary feature is lossless trimming and cutting of video and audio files, which is particularly useful for reducing the size of large video files captured from devices like GoPro, drones, or video cameras.
