I'm trying to encode a video for DVD in HCenc, but I keep having problems with I-frame pulsing. I've tried several different matrices with little or no improvement, so I think the problem must lie with one of my other settings. The source is uncompressed, downscaled from edited HDV. It is fairly noisy in some parts, which makes the pulsing more noticeable, but it can be seen on clean frames, as well.

If someone can suggest a way to improve my encode, I would be very grateful. I want this film to be as high quality as I can get it.

Here is my HC.ini:

Code:

*BITRATE          7950
*MAXBITRATE       9000
*FRAMES           0 105168
*PROFILE          best
*GOP              12 0
*PROGRESSIVE
*AVSMEMORY        128
*PULLDOWN
*INTRAVLC         2
*MATRIX           mpeg
*LUMGAIN          3
