Special settings for animation?

[dragonstout]

I'm making a backup of my Simpsons DVDs using DVD Rebuilder and CCE SP 2.50; however, I'm told that animation usually compresses poorly. Are there any settings that should be changed to more appropriately compress animation? Thanks!

I recently did a backup of Finding Nemo with CCE 3 pass mode and no special parms and the result was OK! :D

Animation does seem to reqire more bitrate than live action to maintain quality due to the high contrast areas (lines). Of over 40 animated discs (all PAL) here are my views:

It all depends on a case-by-case basis. I feel that a clean source with little noise (the recent digital anime over the old hand-drawn stuff) doesn't require filters.

Grainy material/below 3500kbs I run a test using undot and deen filters found here> http://www.avisynth.org/warpenterprises/ Undot and deen tend to smooth out the solid areas - both are filters designed to reduce noise.

Enter undot().deen() in AVS Options -> Advanced Options -> Filter Editor. place the .dll

The inbuilt filters in CCE 2.67+ seem to make neglible effect.

Try a small segment of footage with the filters and without and see which looks better.

How do you run a test? Using RB-Opt?

I'm having a problem with flickering on an anime OAV DVD where the video alone is almost 8 GB. It seems to be hand drawn then scanned. The flickering occurs when you have lines drawn close together as in blinds or stripped shirts. IIRC from signal processing (ages ago) there is a sampling error caused by too low of a sampling rate when you have rapidly changing patterns. IIRC it was called aliasing. Don't know if this is the same thing or not. My memory may be more than a little fuzzy. The average bitrate is approx 3500.

I tried undot().deen() and mssharpen() independently and it still flickered when I played those scenes from RB-Opt Then I tried undot().deen().mssharpen() and flickering stopped when viewed from RB-Opt. Yet after encoding, there was still some flickering when I played the filtered, encoded source in PowerDVD.

I am looking at filters called antiflicker and vaguedenoiser. There doesn't seem to be a filter specifically for aliasing.

Any suggestions or tips?

In RB-Opt there is also the possibility to use other matrices (for low bitrate for ex.; I've tried these and they work well. I've done dances with wolves at an ABR of <2000 kbtis/s and it looked acceptable; with undot().deen() and the "low bitrate" matrice). IIRC, there is also one or two specially for anime. maybe it's worth a try.
