Converting MKV to MP4

Daedroth · 29/05/13 - 01:48

I have a bunch of mkv videos that I need converting to mp4, but don't have the time to re-encode each and every video. Is there a quick way just to swap container?

Edit: I'm using Windows 7.

Thanks for the response, but that only works on a Mac doesn't it? I should have added my OS into the thread when I created it. (I have now)

What about this?

You can trivially remux them in to the new container.

It depends how you lean. There is a tool called yamb which is a GUI front end for the de facto mp4 muxer mp4box. You may need to demux first though with mkvtools.

If it were me though I would use my goto transcoder called mediacoder and set the audio and video to copy (so there is no recoding,) and the container to mp4. This will do you a nice batch job in no time at all. Or at least as fast as your hard disk can do it.

I have just used hat and it did a 1.1GB file in 2 minutes 26 seconds, and the output file was 0.99GB. So this is good.

Thanks for the link.

I will look at this.

I've tried to understand this type of thing before, remuxing, transcoding, re-encoding, converting, etc and it did baffle me a little.

If you've lost 10% of the file size you have probably lost something in the process. Maybe a second audio track. The sizes should be within a few meg.

Using MediaCoder took 1 minute and 20 seconds to complete (having selected copy both audio and video). The input file was 1.1GB and this has the output at 1.05GB.

Of you are going by the transcoding complete dialogue then that may be a rounding issue.

If you want to have a good look in the files mediainfo is a great tool.

I think I might stick with MkvtoMp4. MediaCoder is playing havoc with my anti-virus. Most likely a false-positive, but the gain wasn't worth it. It seems to be working well, so I'll see whether they're play correctly on other devices.

Edit: Now that's annoying.

MKV would play on the TV but not the iPad. Now the converted MP4 will play on the iPad but not on the TV. Bleh.

Hey there!
