I wasn't able to find a solution for this elsewhere:
How can I encode with x264 (i.e. in HandBrake) and have it keep frames of solid black or white color? These appear fairly often in TASes, however in my experience, the codec will replace them with a freeze frame of the last non-solid color frame. This usually looks strange and not fully accurate to the source.
A recent example is
Weatherton's MK64 encode, where the lack of fully black frames is seen as early as 12 seconds in. Notice how the words "Player Select" stay on screen for a while instead of going black right away, and later how the colored boxes at 1:11 never fully leave the screen. I don't believe this happens in BizHawk or on console.
