MKV isn't really a format. It's a container. Chances are, you'd be looking at MPEG-4 video and AAC audio in that container, which may very well be better for YouTube but those same audio and video tracks can reside just as happily in an MP4 container.
To sum up what I'm trying to say, check your video and audio codecs if you're going to switch containers. That being said, I'm not sure if this will really even make a difference if this is the first of many videos, all recorded and uploaded in the same way, that exhibits these symptoms. I'd need to look into it a bit more before being able to go into any more detail but I can't do that from my phone.
