Hi Ren,

What are you using to encode :?: MencodeME or PackShot :?:
What is your target resolution :?:
What is your source :?:
What settings are you using :?:
Using an .avs, or encoding from VOB :?:
Too many questions :lol:

hey kwag,

I'm using MencodeME with dvd source and target kvcd (352x240) via avisynth. The avs is simple- just resizing, deinterlace and limiter. At this point I'm thinkin' it might be related to limiter() but I really don't know what 'dct coefficient' means 8O

Thanks,
ren

Hi Ren,

Try a direct encode from your VOB, and see if you get the same results.

I think by 352x240 he automatically uses mpeg1 or not??
And didnt we had much issues according to mpeg1?

@ren,

I Changed to mpeg-2 as output file with resolution 704X480 (kvcd3x) and
dtc errors went away. My source is still .d2v with fakeavis as .avi and
all works well. Try Kwag's temp.conf settings and the target file size
is perfect. The picture quality is outstanding!! :mrgreen: During fast action secnes
near the end of the movie seems to be very blocky and gibbs effects.
I'm only using 1 pass and still experimenting with 2 pass to get a logfile
to correct this in the second pass. :)

Funny enough I was getting those after packshot & it's bat file. I changed
vrc_eq=tex to vhq=1, and they went away.

* I thought they were the same thing - that's how mencoder's manual reads to me.. *
