Fastest way to convert MKV to MP4?
#1
I'm not sure if there is already a thread about this, but I'm trying to convert an MKV file to an MP4 file. I can convert the other way in a minute with MKVToolNix, but not the other way. I can't seem to figure out MyGUI either and I can't seem to find anything else online that looks trustworthy, so I thought to ask here.

Why do you need to convert MKV to MP4? What is the file being used for? 

Also, the thread says "fastest way". Is time an issue? Are you going for speed over quality? 

A Google will reveal many options for a quick convert, but you probably won't get a satisfying result. 

I believe Handbrake will convert MKV to MP4, but it won't be lossless.

My guess is to edit in Sony Vegas because that's the only reason I can think of to convert to mp4. 

The important thing to understand is that your video is probably H264, mp4 and mkv are just containers. You definitely don't want to do something like Handbrake, or any conversion for that matter or you'll lose quality. And it'll take a long time, if you care about that. You just want to switch containers, no conversion of video file at all. Something like Mp4Box should do the trick easily and free.

It's to edit in Premiere, but yes. 

Also, how exactly does MP4Box work, it just appears to be a player for video files with a console

I don't know what Premiere is like, but it never worked for me when I just switched containers for Vegas. 

How come you've got an MKV in the first place? Is that your source or did you make the MKV from a DVD/Blu Ray? If MKV isn't your starting point, then there might be better ways for you to get it into an editable format.

Edit: Also, there are some suggestions for your predicament on this thread: https://forums.fanedit.org/showthread.php?tid=11799

It's one of kk650's regrades that is an MKV that needed to be converted to an MP4 so that I could tinker with it. 

I've figured it out now though using ffmpeg. The code is below for anyone that wants to use it

Code:
ffmpeg -i input.mkv -codec copy output.mp4

It switches containers without any quality loss, and in only a few minutes too, so I seem to have solved my own problem.

Any way to do that on Mac?

Not that I know of, but I'm sure you could find something if you look up "ffmpeg mac" or something to that effect

Does that only work if the codec is h264? I've looked for a way to convert an mkv ripped from the bluray using makemkv but cant find a way to change the container to mp4 for editing without recoding it. my usual way is to create a high quality mp4 from the BR using handbrake on all the best settings.

That should work I think, I'm not fully sure how ffmpeg works, only that it's some magical progam that converts/remuxes anything to anything.
