   does a specific job very well

   LosslessCut makes it very easy to cut out a section of video. It can also arrange sequences of cuts. It is very fast because it does not reformat the data; that also means it doesn't degrade the quality.

   It only reliably cuts at video keyframes; this could be an issue if you want 100% precision on your cuts. It does not attempt other editing tasks such as reformat or region crop.

   Like many video editors it is a GUI to ffmpeg. You can see the ffmpeg commands generated and use them outside LosslessCut if necessary.

   👍 Pros:    Easy to use|Fast

   👎 Cons:    Limited features

• Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months

  For lossless cut, there's the LosslessCut [1] app, which even has an experimental but mostly working version of a "smart cut" feature [2] (aka. Only re-encode the minimal mandatory amount of frames if you trim at a point between 2 key frames) [1]: https://github.com/mifi/lossless-cut. - Source: Hacker News / 14 days ago

• Cleaning up my 200GB iCloud with some JavaScript

  > thought I cropped/edited a video, it is still there in full length and resolution It's been possible to create a clip from a video file that merely changes what parts of the video are displayed without effecting the data in the original since the Classic Mac OS days. If you want to completely remove unwanted portions of a video to reduce the size without a loss of quality, there are many options. LosslessCut is... - Source: Hacker News / 4 months ago

• FFmpeg is getting better with multithreaded transcoding pipelines

  Https://www.vapoursynth.com/ I have seen some niche software built on ffmpeg like losslesscut: https://github.com/mifi/lossless-cut But I don't know anything "comprehensive.". - Source: Hacker News / 6 months ago

• Lossless Cut is my new favourite tool to cut parts from a video without any hassle

  Lossless Cut is probably the simplest way to cut out parts of a video without having to re-encode it or use an online service. It is open source, free and available for all platforms. It is in essence a frontend for FFMPEG and cuts without re-encoding, so the results are instantaneous. - Source: dev.to / 7 months ago

• Tips and utilities to manage collections of videos.

  Additionally I would like if possible to shorten (both to reduce dimension and to make them less boring) my videos by trimming the beginning and/or ends where often there is nothing interesting happening and possibly change the thumbnails for easier identification. Do you know of any tool that does the job with the minimum quality degradation possible? Many years ago I've tried with some videos and a tool I don't... Source: 7 months ago

• TRUEHD 7.1 Slow Down

  Fourth, try remuxing one of the problem files. Use the Multiplexer section of MKVToolNix. This will copy the contents to a new MKV file. It is like putting a letter in a new envelope when the original is damaged, but the pages inside are OK. Source: 5 months ago

• Remove Audio Commentary over TV shows

  If the audio tracks are displayed as unknown, the language flag needs to be set. Use tools such as MKVToolNix Header Editor to configure the language for audio & subtitle tracks. Source: 10 months ago

• /r/Plex's Moronic Mondays' No Stupid Questions Thread - 2023-07-10

  As for extracting tracks from MKVs, the low-level way would be to use ffmpeg directly (something like ffmpeg -i video.mkv -map 0:s:0 subtitle.sup would extract the first subtitle stream to a .sup file, the extension used for standalone PGS subtitles), but something like MKVToolNix can probably do it as well. That won't help you too much on its own though, since you now just have an external image-based subtitle... Source: 10 months ago

• Advice needed on anime series with two audio language versions.

  You could use a tool outside of Plex (like MKVToolNix) to combine the video+audio of one version with the audio+subtitles of the other. It gets trickier, or at least more tedious, if the videos aren't exactly the same, since you'd then have to account for any audio/subtitle shifting. Source: 10 months ago

• Plex isn't syncing episodes into database

  Option 3: Change to MKV container. Use MKVToolNix or similar tools and remux to a MKV container. Note that this may cause problems with Dolby Vision. LG TVs must have Dolby Vision in a MP4 container, otherwise the video will not play correctly. Probably affects other Plex clients as well. Source: 10 months ago
