x264 parameters for screencasts

[MySchizoBuddy]

Any help with optimal parameters for a 800x600 screencapture using x264.
thanks.

Computer screen capture, like of ordinary Windows programs (not video/etc)?

I'd try turning off deblocking; I'd think that in screen capture it would only have a negative effect due to the large areas of solid color.

High subme is definitely useful, along with a strong motion search to catch motion. I'd think multiple reference frames would also be quite useful, along with all partition types, including p4x4.

Assuming you don't have to do live encoding, and don't care too much about speed, I'd use:

--bime --bframes 16 --weightb --subme 7 --ref 16 --me umh --merange 24 --trellis 1 --b-rdo --partitions all --direct auto --b-pyramid --8x8dct

thankyou
yes screencapturing windows, mouse pointers, for tutorials. solid colors with lot of text
It would be recorded live using Apple Animation (lossless) codec so CPU is not choked and i get good framerate. Later will do the conversion to H.264 to be used with latest Flash player.
yes speed isn't important , only good quality (so to actually be able to read text) and dinky size.

i'll try your preset

i'll try your presetRemember of course to choose the necessary bitrate or CRF parameter--and if you're encoding in bitrate mode, choose 2pass for maximum quality.

For CRF (constant quality), try 22 or 25 for a base; raise it higher for lower bitrate, and lower for higher quality.

ok no-fast-pskip should be skipped cause its related to deblocking solid colors,

high bframe number
high ref number
low ratio for delta I,P,B quantizer
