Screen capture will always be slow, because the video adapters and drivers
are optimized for output rather than capture. VLC cannot fix that. There is
no way in hell that you could reach 30 frames per seconds with screen:// on
any common computer. One or two frames per second is more realistic.
Besides, it is not unlikely that your computer cannot encode such a high
resolution and rate to MPEG4 in real-time.
