For better filming it might be useful to start drawing the frame when the hdmi vsync fires. currently the mac output draws at a constant speed, but it could instead (when HDMI is locked) use the vsync signal pulse instead.
The 125 MHz clock could also be divided by 8 for a 15.625 MHz clock that would be a better match (?) for the 15.71 that the schematic has for the Mac Plus. This might expand the screen out sideways slightly.
