The shitty thing about mame videos I see on youtube is they are at 30 fps and don't do any blending to make up for the frame tosses. Mame records a perfect copy of about double that and then youtube just drops every other frame so nothing looks how it should. It's all choppy. It doesn't happen when you record a pcb through svideo even if you are recording at 30 fps, you get a more correct blend of frames. The easiest game to see the damage aside from jerkiness on is probably Dangun Feveron. The pickup men have a translucent red made by flickering on and off quickly. If you record it from a board it preserves the translucency, uploaded mame recordings have it blink on for a second then off which looks completely incorrect.
