even with the default settings as in the script, the quality is reasonable. artifacts are only really noticable in graphics and lettering on signs etc.
And with respect to size ?
about 400-450MB per hour, which is a lot better than ~3GB/hour.
that's for the one-pass version. haven't actually tried the two (three :) pass version yet.
i tried the three-pass version yesterday afternoon. for a one-hour recording, with transcoding done on my amd64 3200:
one-pass took 37 minutes and resulted in a file 381MB in size. (transcoding at approx 50fps)
three-pass took 206 minutes and resulted in a file 707MB in size. (transcoding at approx 227fps for pass1, 50fps for pass 2, and only 8fps for pass 3)
quality was excellent on both versions. the one-pass seemed very slightly fuzzy in comparison to the three-pass, but it was only noticable if you were looking for it....and even then, i'm not 100% sure that i didn't just imagine it because i was expecting it to be worse.
and that was in full-screen mode on my 21" monitor less than a foot from my eyes. when i set up my dedicated VDR machine connected to my TV about 10 feet from my eyes, it probably wont be noticable at all.
i don't think i'll bother with 2/3 passes any more.
