Splitting Clips about pyscenedetect

[Breakthrough]

Hey @rhefner1;

One last update for you, I managed to integrate calling mkvmerge into the latest version of PySceneDetect (v0.4), so now when the -o option is specified, the input video will be split into individual scenes (albeit as .mkv format).

Hi @rhefner1;

I've been meaning to add this to PySceneDetect for a while, but the OpenCV video encoding options are rather limited (only letting you select a codec, and nothing else, not even bitrate).

One quick tool you can use for this is mkvmerge (or mkvtoolnix-gui), and copy/paste the comma-separated timecodes into the file splitting section. This doesn't reencode the video, just re-muxes it. The section of the mkvmerge docs is here that covers using the --split flag:

mkvmerge -o output_scene.mkv --split timecodes:00:45:00.000,01:20:00.250,[...] input_file.avi

For ffmpeg, there's command line flags to set the start/end/duration of the input, copying the video container. This should achieve the same results as using mkvtoolnix, although I think you would have to make a call to ffmpeg for each scene you wanted to extract from the input file.

I'll look into adding support for integrated clip splitting by calling mkvmerge/ffmpeg directly from PySceneDetect, and I'll also work on a short tutorial/guide on splitting a video via timecodes to that page you pointed out.

Thanks for the comment & feedback, let me know what method you find works the best.

@Breakthrough: I just did a test with both mkvmerge with the command you provided and mkvtoolnix-gui and both worked perfectly!

I'm splitting up some home movies and a few years ago had tried doing it manually but gave up. All I have to do here is write a little Bash script and it's done. Thanks for the help and the great tool!

@rhefner1 glad you're finding it useful, that reminds me I have some older home video footage I need to apply this to myself.

Thanks again for your feedback, I've updated that particular section of the documentation (if you think this should be mentioned anywhere else, feel free to let me know).

👍 thanks!

@Breakthrough that's fantastic. Thanks for your work!
