MKV

What are you trying to edit in the MKV?

I'd say you'd need to demux it first ..... then work with it.

Muxing is the process of combining the audio and video files into a single container format (in this case an MKV). Demuxing is the opposite of that. TBH, if you demux an AVC file from an MKV and try to open it in Premiere you may still have trouble. Premiere imports M2TS files no problem, so you may want to try re-muxing from the MKV to an M2TS file using Tsmuxer or a similar application.

Be aware though that Premiere isn't very quick when working with compressed files and I've had problems with it decoding frames correctly before from AVC video streams. I export from MKV to a Lagarith lossless AVI before trying to manipulate the video. The files are very large, but then Premiere itself creates a huge cache of decoded video anyway if working with AVC!

I don't know, but will hazard a guess that you will have a similar experience no matter which NLE (non-linear editor) you choose. They all seem to support similar formats and you will probably get the same speed out of them when working with AVC encoded files.

Any NLE will have to spend the time decoding the frames and, depending on the AVC profile, there is no guarantee it will be decoded correctly.

It would seem best is to just give it a try. Re-mux your MKV to M2TS, import to your preferred NLE and see how you get on with it.

Is there a free program that can convert MKV over to an AVCHD?  I can't watch that great-looking Back to the Future DCP because the bitrate is too high for my computer to play smoothly.  I know I'd be sacrificing some quality, but I'm sure it will still look amazing as an AVCHD.

 I am trying to work with a remuxed m2ts file in Premiere. But the audio is DTS. As I expected, this doesn't load into Premiere (though the video track seems fine). I would really like edit points to occur simultaneously in Premiere or After Effects (or whatever other program I end up using). Surely there is a way to accomplish this?

Thanks

The approach that works for me is to convert the DTS to WAV (using TFM audio tool) and just sync and link the sound to the picture in Premiere.

Thanks. I was considering conversion as the best option. So long as I can attach every track to the video and have them move/cut/whatever cleanly and in sync, this sounds good.

edit: It looks like I've got it figured out.

I use this program to convert my MKV files.  It's 100% free,supports a tone of formats,and even has a simple video editor.  it's not the most complex program out there and you have to play around to find all the right settings but it does the job,takes every file I throw at it and did I mention that it is completely free?!

It really is a god sent to people like me who have no cash but want to work with HD video.
