can i use mvktoolnix to edit (cut out fragments)

[vmrsss]

Hello.

I have encoded a piece of DVB (h264+aac+idx) and muxed with mkvmerge. I then realised I forgot to cut out the commercials. Rather than re-encoding from scratch (which of course I could), I am thinking: can I use mkvtoolnix to cut out the unwanted parts from the mkv file? (Eg, mkvextract fragments between keyframes --but this seems not to be possible-- and then mkvmerge them?)

If not, any suggestion of a tool?

In the global tab of mkvmerge guy you can find options to split the file. You have to split them first and then append the parts again leaving out the commercials. Mkvmerge will only split on keyframes and I don't know any program that does "smart rendering" for h264 like you can do with VirtualDub for Xvid.

Thanks, sound promising, good idea.
