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
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
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
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
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
"Regular" people don't really need FFMPEG. Regular people need tools with GUIs that have a non-generic purpose. So stuff like https://kdenlive.org/en/ that are backed by ffmpeg are (imo) superior "regular" person tools. FFMPEG isn't complicated (its as complicated as any other CLI tool), it's that video encoding/decoding specifically is a hard problem space that you have to explicitly learn to better understand... - Source: Hacker News / 22 days ago
Great that you got it to work. Just to make the list with potential tools a bit more complete: - Kdenlive is also a fairly capable video editor. https://kdenlive.org/en/ - From what I have heard the Blender video editor for many people is a go to tool as well. In this case it likely would have been overkill, but figured it is worth mentioning. - Source: Hacker News / 3 months ago
You might be interested in Kdenlive. It's not online, but can be installed on any OS and I've had it running on some pretty dated machines. Source: 5 months ago
Kdenlive or shotcut for small/basic stuff. If you're outgrow those, then DaVinci Resolve Free. Source: 11 months ago
Some free options include Kdenlive and Shotcut. I would have previously recommended Wondershare Filmora, but they recently did some pretty shady things with their licensing and I'd avoid them now despite the software actually being quite good. Source: 11 months ago
