Screen capturing is slow because ReadPixelArray() is slow. Applications can't accelerate it.

I can't remember if ScreenRecorder scaled it down (using blitter) before ReadPixelArray() (havent touched it lately...) but you hardly see anything if FullHD is scaled down to 320x200...

Quarter of screen size of 1920x1080 pixels would be 960x540 pixels and using 16bits instead of 32bits may help a little. It's still 1MB per frame so not fast to read and later encode.


16-bit screens look so crappy it is an insult... but it would help if Screen Recorder just dumped screen to HD and encoded it later. At 15/30 fps you could get acceptable results.

Screen Recorder also allows recording smaller area under mouse pointer. This should produce interesting videos, too.
