I'm unsure if this is the right topic to ask this, but here goes: why do my good quality 1280x760 videos (with screen captures for instructions) end up looking like rubbish after uploading to Youtube?
If I watch them immediately after Youtube says they're OK, then they are (OK).
But 5-10mins afterwards, they suddenly look very bad. And it seems there is no difference what screen resolution the user asks for.
So how do I get _real_ HD video uploaded to Youtube????
