Mpv: Use mpv for cutting up videos

Created on 21 Jan 2017 · 4Comments · Source: mpv-player/mpv

I wanted to suggest a feature, with which mpv could be used to cut videos up.

Usually, I'd so it with ffmepg, like this this:

ffmpeg -i input.wmv -ss 00:00:30.0 -c copy -t 00:00:10.0 output.wmv

The problem is, that I always have to calculate how long the file would have to be (for -t), and since I already use mpv for finding out when to start and end the video, I thought one could add a feature, to do this automatically.

I'd imagine, this could be done, by, e.g. pressing a to set the beginning of the video, and then c to cut from the point set with a until now. Then the video could be cut (which wouldn't take long, if one only copies) into a separate file, just like with screenshots. One could now debate, whether the point in time when a was set gets forgotten after cutting the video, or if it's remembered, what happens if a specifies a moment after c, etc.

(In case this feature already exists, I apologize for suggesting it, but I couldn't find anything about it in the official documentation)
