I'm sure people will discover that all sorts of problems will manifest if they don't start a lossless clip on a keyframe. One such scenario is when you make a clip that plays perfect on your PC, but then you send it someone over FB Messenger, and all of a sudden there's a few seconds of extra video at the start!
