mod 8 resolutions and macroblocking...

[Fr4nz]

Hi guys! Should I stick with mod 16 resolutions or I could try also with mod 8 resolutions? Is it possible that with mod 8 resolutions the codec creates some macroblocking effects?

Thanks for any answer!

And one more thing. Many people insist on messing around with the W-Modul and H-Modul. I highly recommend leaving them at their default values of 32 and 16. There is a case that can be made for setting them both to 32 (better compressibility, although it limits the resolutions available to you). And you can probably get away with setting them both to 16 (but with less compatibility). But for both compressibility and compatibility reasons, you should not set either of them to 8 or lower. TheWEF explains the reasons for this:
=============================================================================

divx is encoded in macroblocks of 16 x 16 pixels.

e.g.:

640 x 272 = 174080 pixels = 680 macroblocks.

640 x 274 = 175360 pixels (0.7% more) = 720 macroblocks (5.9% more).

more macroblocks - more compression overhead.

for compressibility reasons i highly recommend to at least use w-mod and h-mod of 16 pixels.

w-mod 32 is recommended for playback compatibility on older gfx-cards.
