Unofficial VirtualDub Support Forums > Codec Discussion > Can I Save A Part Of An Mkv Without Recompression

Posted by: MhXDigital Sep 21 2011, 10:20 AM

Hi guys, I've started using the external encoders feature a few months ago and I'm really happy with it. I'm just wondering, is it possible to save a small part of an MKV video without recompression ? I need this to make samples of my videos. I've heared that ffmpeg can do it through the command argument -vcopy or something like that, but I don't know how to set it. Any help will be appreciated, thanks in advance.
