Simple program to convert mkv to mp4?

[Ronaldinho]

Hello,

could someone please suggest to me a simple program that will allow me to mux an h.264 mkv file into an mp4 container? I've tried mkvtomp4 but that didn't work for some reason, just stayed at 99% the whole time, and I tried meGUI but have no idea how to use it.

Any help would be much appreciated, thanks.

Not all mkvs can be remuxed to a mp4 container.

But you can always try avidemux, open mkv, under video and audio choose copy, under container mp4, save. It will probably crash though...

Or from a command line, ffmpeg -i video.mkv -vcodec copy -acodec copy video.mp4

If everything fails you might have to reconvert the audio or video. Post the details from the mkv then.

Okay, so how do I use a command line?

[Baldrick]

Download ffmpeg(get the latest static 32bit build), extract ffmpeg.exe, put it in for example c:\temp together with your mkv file.
Start a command prompt from the windows start menu and under accessories.
Type
cd c:\temp
ffmpeg -i "video.mkv" -vcodec copy -acodec copy video.mp4

Okay, i will give it a try, but I should have asked you this before... Can i still do this without any audio?

I just need the video stream, no audio. In fact it's crucial that I don't have any audio in the file (don't ask, long story).

[Baldrick]

Yes. Instead of -acodec copy use -an

ffmpeg -i "video.mkv" -vcodec copy -an video.mp4

Okay, will give it a go now

Thanks

Okay,

It kind of worked, but the mp4 file is horribly choppy. I don't know what i've done wrong..

[Ronaldinho]

Nevermind, Baldrick. I just tried avidemux and that worked perfectly. So I will just keep using that for now.

Thanks for your help

Great!

You can also try Video To Video Converter. When you open an MKV for conversion, select Direct Stream Copy from the conversion presets.
