#74174 — Changing video file type witout re-encoding (MKV)

As certain video programming does not support .MKV file types, one needs
to convert files to a supported format.

While Handbrake does the job, it only does it by re-encoding the video.
(there is a pass through option for audio, but not for video).

I did a cursory look for a utility that can just unpack a MKV and repack
the same content into a different container type such as .MOV .AVI or
whatever.

I looked into MKVtools, but like handbrake, it appears to rebuild the
contents instead of just changing container (and the test version is
useless since it embeds its watermark which means it re-encodes the
video and modifies it).

Any hints on a simple utility that can just change the container file
format (or even split the MKV contents into video, audio, subtitles etc)
files ?

Many many thanks. Took a while to get a working ffmpeg executable (and
no man page), but I got it working. To extract only the video, I had to
have a -an flag to it otherwise ffmpeg would not work.

Oh. Sorry. I was thinking ffmpeg (some version) shipped with OS X. I 
remember now that it's one of the things I instantly build on any new 
Mac system (along with ncftp and an updated rsync).

There was once a GUI version:

http://www.ffmpegx.com/

but I've never used it and it doesn't look like it's being maintained. 
And ffmpeg is an incredibly deep application; I'm not sure how one could 
built all it's complex invocations into a "click-here" app. You can find 
the man page online.

Also -- not sure about subtitles (which you mentioned at one point) in 
avi. You'd probably have to ship a separate file.

But but --

 -an would disable the audio, no? What audio did your avi contain?

Yeah, in my quest for ffmpeg,  I stumbled on that one. i stumbled on
another ffmpeg download that requires ".7z" decoder instead of zip, so I
had to hunt for such a decoder only to find that the .7z archive didn't
contain a OS-X executable (likely windows or perhaps powerPC - can
PowerPc apps run at the Unix shell ? )

Not concerned about it so much.

>  -an would disable the audio, no? What audio did your avi contain?

The intent was to merge the stereo audio from DVD, into the 1080p
version whose sound was the original mono. So there was no point in
having the mono audio into the "temporary" file that I would import into
Premiere where I woudl merge in the stereo audio.

Along with colour correction/white balance, it takes about 20 hours to
re-encode that movie.

Just for the sake of being complete, here's a not so well known one -

What is that site? Does it have a front page?

Damned .... after 14 hours of processing, the movie with a silent sound
track.  It's there in the specs, but it doesn't generate ANY sound (the
stereo doesn't indicate arrival of a signal).

But the image is fine, much improved over original so that isn't lost.

I found out CS6 has "audition". It has a "convert to 5.1" "Favourite.
So now, I have to watch plenty of view and do googling to learn what if
can do and if it is of any of use :-)

The Little App Factory have written a few good tools.
RipIt is a DVD ripper, and Evom is a media converter.
I haven't tried any of their others, but these two
work quite well.
