MKV cutting with Avidemux

[loa-ash]

Hello guys,

I've a problem with a cut of mkv+x264 file. After deleted the parts with the buttons A and B I've saved the file, but when I play video on every player it's very slow but audio has no problem. Maybe when I save the file on avidemux i need to change Video: copy and Audio: copy choosing some compression mode?

thanks

How did you make the MKV file? Avidemux is pretty good for general cutting but has some known issues.

I created the MKV with MeGUI then I've add some cuts to script with megui too:

DirectShowSource("M:\Mythbusters.mkv", fps=25.000, audio=true, convertfps=true)
#deinterlace
#crop
#resize
#denoise

__film = last
__t0 = __film.trim(0, 8851)
__t1 = __film.trim(14396, 38847)
__t2 = __film.trim(43500, 67848)
__t3 = __film.trim(73151, 80567)
FadeOut(__t0, 0, AudioRate(__film)) ++ FadeIO(__t1, 0, AudioRate(__film)) ++ FadeIO(__t2, 0, AudioRate(__film)) ++ FadeIn(__t3, 0, AudioRate(__film))


but I don't know how to do for audio...

Maybe i've resolved my problem with megui... before enconding I add cuts to script with parts of video that i want to save, then I save cuts to file and I load it when I need encode the audio so this will be correct?

Yeah, that'll work. But why are you starting from the Matroska file? Do it on the original encode, or else you're recompressing twice for no real reason.

Sadly i've deleted the original source, I'm trying just now but when i load my .avs and cuts for cutting audio I receive this error from log of megui:

Output from encoder via stderr
