"I have some video files in Matroska format (MKV). They don't seem to drag/drop onto the Vegas 11 timeline. Any workarounds to use MKV files in on Vegas timeline or will I have to convert them to another format first?"
Sony Vegas Pro is a professional program for creating and editing videos for amateurs, YouTube bloggers, and vloggers. The program works with plenty of video and audio tracks. However, till now, MKV has not been added to the official supported format list of Sony Vegas Pro. Another reason is that "can't import MKV in Sony Vegas Pro" problem still happens every now and then, mostly for codec missing. To overcome the incompatibility with using MKV video in Sony Vegas Pro, transcoding MKV file is the the most effective yet easiest solution recommended by us.
Why can't MKV be imported in Sony Vegas Pro?
You should know that the codec format decides whether you can load a video or audio file successfully or not, while MKV is just a container forma that can contain different types of video and audio. The container format itself tells you nothing about the content. The reason you are having problems is that the video (and audio) format inside this particular file is not supported by Vegas, which leads to file import failure. To fix MKV file not supported in Sony Vegas, the best option is to convert MKV to Sony Vegas Pro editing-friendly formats, such as MP4, MPEG-2, etc.
Note: Someone suggested to install certain codec packs that Vegas will use as it's default codec. I don't believe this will work because MKV is not just a codec it's a container as well and it's a container that Vegas Pro doesn't support. BTW, installing a codec pack on your video editing computer may permanently mess it up unless you know what you are doing where most people who think they know what they are doing really don't. Just don't do it, there is never a need for it. Only install the one codec that you need from a reputable source. Installing a codec pack is like taking every pill in your medicine cabinet hoping one of them will cure you… one of the might but the rest could kill you!
