For a specific MKV to h.264 convert I recently discovered a free tool for Windows and Mac called MP4Tools. It works wonders and is fast. I believe there is another called AVITools that converts MKV to AVI, but I don't necessarily see a need for AVI personally. MP4Tools will create the video in an m4v wrapper, but I haven't had any issue using that in premiere or converting it to a more uncompressed format.

Premiere Pro CS6 doesn't support MKV formats. To import MKV to Premiere Pro CS6, a recommended solution is to convert MKV to AVI.
I've been reading so many different forums on how to convert MKV to AVI. Finally, I summarised three solutions:
First one: HandBrake . This tool is a free and open-source multi-threaded transcoding app. It supports nearly any videos including MKV format and has Mac version and Windows version.
1. HandBrake is too professional to handle for most people;
2. It doesn't support MOV as output format.
Second one: there are many third party software which supports converting MKV to AVI. I just test one of them. It's professional yet easy to use and the service is excellent. And there is a step by step guide about how to use this tool .
1. Most of them are not free.
Third one: Online-Converter . This kind of converter does a great job on file conversion.
1. Like most online converters, the free version of this tool only allows you to convert videos smaller than 100MB. It's too small for video conversion;
2.Your MKV video should be upload to the internet to be converted. This means the risk of pravite information leak is possible.
MP4Tools is an excellent app and quite speedy too since it is only duplicating the data inside the MKV wrapper to an MP4 wrapper. The only thing it usually needs to process is the audio, which is plenty fast (compared to video encoding
I'm guessing all the other crazy formats from RED, ARRI, Sony and Panasonic are super specific specifications. Whereas MKV could contain any bizarre codec.
But yeah, Premiere *should* be able to handle h264 MKVs at the very least.
Convert MKV to an editable format. Use Google to find a converter.
SEVERE WARNING: do not install something like K-Lite codec packs. That will generally require a complete reformat of your boot disk and a complete fresh install of OS and programs. A typical SNAFU (systems normal, all fouled up) situation.
due to an antiquated agreement between Adobe and Apple, its very difficult for Adobe to incorporate new technology. Its an embarrassing limitation that they dont like to talk about, plus its financially beneficial to them. Its especially true for open source and trending standards. So even though every expert and professional knows that mkv and h264 (now h265) are the best containers and compressive formats available, Adobre *still* wont be able to provide them. If you look closely Adobe is always 2 standards behind.
So if you use Premeire Pro you better get use to using a long list of other tools as well.
PS. Handbrake is *not* difficult - just use the defaults.
Update: Convert mkv to mp4 quickly.
Use VLC, run it, click Media->Convert, add the source, click Save, choose destination, Start.
If you click Settings by Profile, you can tell VLC to "Keep original video" and "keep original audio" = conversion of 2hr movie takes 5 seconds !!
