ffmpeg time-code

[Bekkeh]

I always do ffmpeg -i "link" -c copy "name".output

That is only when I want the whole thing, but how do I do if I for example want a certain part of a video?

[[ss]vegeta]

ffmpeg -i "link" -ss 00:00:20 -to 00:00:30 -c copy "name".output

[Bekkeh]

ffmpeg -i "link" -ss 00:00:20 -to 00:00:30 -c copy "name".output

I don't know, but it just ends after a few seconds without taking down anything at all. Am I typing it wrong in the time stamps?

I want it from 36:48 to 53:50. Or is it telling me I have an old version of ffmpeg? I can download pretty much everything expect this?

For me you have to download it all first, and then you can cut it.


If you want streamcopy (no new encoding) then -ss searches for the keyframe before the specified time in seconds and -to until the specified time in seconds or -t for that many seconds from the keyframe.

For this reason, streamcopy cannot be frame-accurate.

If you want to be frame accurate then you have to recode, e.g.

ffmpeg -i "input" -ss 00:00:20 -to 00:00:30 -c libx264 -crf 15 -c:a copy "output"

See here: https://trac.ffmpeg.org/wiki/Seeking

I don't know, but it just ends after a few seconds without taking down anything at all. Am I typing it wrong in the time stamps?

You can try this also

yt-dlp "https://www.svtplay.se/video/jXAp2GX/carina-bergfeldt/claes-bang-och-mia-parnevik-hos-carina-bergfeldt?position=3217&id=jXAp2GX" --download-sections *00:36:48-00:53:50

Worked for me.

I read everything, but I'm supposed I should read this part only?

https://trac.ffmpeg.org/wiki/Seeking#Cuttingsmallsections

So "input" here is the link right? Why do have "libx264" and "-crf 15" in your code? What is "a" after the c and colon?

Yes, but the thing is I want to understand what I do so I don't need to rely on people here. I assume that yt-dlp works in ffmpeg ?

yt-dlp works WITH ffmpeg
