Screencapture Codec any advantage to normal Codec

[islondo]

Hello,

can anyone tell me in which occasions it is recommended to take a special screen grabber/capture codec instead of a normal Codec like divx or x264?
Also can anyone tell me how a screencapture works or whats the difference between the other video codecs? Is it right that the screencapture codecs are lossless?

Regards,
islondo

Hi
When I've done screen capture I used x264 -preset ultrafast -crf 0.
This is 'lossless' settings for x264. And I use PCM or FLAC for the audio track.
Creates very big files.
The reason is so that the PC can capture in 'real-time'.
My PC would not be able to keep up if it was trying to capture and compress at the same time.
When the capture is finished, then I convert from lossless to compressed, in my own time.

Other people may use different methods, though.
