size problem with black & white video

[nek]

hi,

i tried to encode a black & white video (very dark also) and the resulting size was far from what i had asked for (half the size)

was the predicted bitrate too low for the size i was asking for ? (the video is 1h20min, 640x336

i encoded it with xvid 1.0 beta3, following the doom9 xvid 1.0 guide (i had already encoded another video using this guide and the size was OK)

i'll try with rc1 tonight

regards

well, i hadn't seen the "grayscale" option, will try using it

Search for "codec saturation" and read the forum rules again. Thank you.
