I'm probably the only one, but my experience with megui was kinda bad
Couldn't play it without VLC (though I think it should be playable with quicktime) and the sound didn't fit the image when I got further into the movie. I don't know if it was because of the movie length or because my computer couldn't handle it though
I think overall the codec is probably really good, might just be a few holes in it that might be good to test if making a guide about it as well! But that's just a suggestion
