KVCD: Reduce Q Level on Certain Scenes?

girv · #1 01-20-2003, 08:08 AM

I'm converting X-Files S1 DVD to 480x576 based on KVCD templates,
~45 minutes per 700Mb CD-R. CQ=85, min=0, max=2500 give a good
result for most of the video (Q level ~3) at the file size I want.

The problem is that some particular scenes have a lot of motion and
look really bad (very blocky) with Q levels above 17! Is there any way
in TMPGEnc CQ / CQ-VBR mode to adjust the bits allocated to a particular
scene?

Thanks,

There's something wrong girv. For 45 minutes on a CD at that CQ, you shouldn't have ANY blocks or artifacts. I would even say that you could reach a CQ=100 and still wouldn't fill the disk. Are you using the latest version 2 templates?

Why don't you try the XVCD (704x576) or the X3 template? I've experienced that due to the smaller blocksize many macroblocks aren't visible on the TV set... I presume that you've used bicubic resize for your file - bilinear resize gives me better results, and I can compensate the resulting lack of sharpness with a higher resolution.
