Inconvenient Truth - undersizing

[archaeo]

Haven't had many problems in the past with sizing in DVD-RB, but this one has been stubborn. :confused: I thought perhaps it might have been because I just upgraded to Avisynth 2.5.6, but I went back to 2.54 to test w/ same settings, and it also came out to same size: 4.12 gb. Any help here appreciated.

My steps:
Ripped with Decrypter, and set RB to Full backup, menu encoding enabled. I used undot()deen() in filters, but have never had a problem with these two filters before.. Matrix used is Auto-Q2, also CCEAQM=0, and CCETargetSectors=2246064

here's my log:

Set CCEAQM=0 to CCEAQM=1 and try 3 passes.

With undot()deen() you are clean up the picture and with Auto-Q2 the encoder is probably having saturation problems. Try CCEAQM=1 and try 3 passes... CCEAQM=1 will help with Auto-Q2 and the saturation... the 3-passes helps with CCEAQM=1 and sizing.

Thanks Fishman for the quick response. So it may be that the combination of filtering and Auto-Q2 is skewing the ouput...
Undot()deen() never gave me much increased compression in the past, but I must say that Auto Q2 seems to be pretty effective for compression. I chose it since the predicted overall was approx 3100, but maybe there was a better choice. However, I'll run this overnight with your suggestions, and report back. (I stress tomorrow because you can see that it took all of 8+ hrs)

[Mug Funky]

this movie is mostly static blackness with a talking person standing still. it'll compress very well.

so yeah, auto matrix in CCE should help you hit the target. i'd drop off some of your filters, too as they're probably not necessary (maybe a deblocker will help things, but the rest should be enough for CCE to handle on it's own).

[jdobbs]

What kind of Q values are you getting? It's possible that you're hitting encoder saturation on some part of the encode. If that's the case -- it's actually a good thing, because it means you are getting the "best you can get".

[archaeo]

I'll have to get back with the results tonite - when I left for work this morning, it was only at 75% complete - 3 passes with a Pentium III takes a LOT of patience.

[archaeo]

Bingo - right on the money at 4.35 gb :)

The Q level of this encode was coming in at around 8, so yes, it looks like saturation was a factor. Surprised to have such a low Q with a 62% compression ratio ... ! But as Mug Funky mentioned, the nature of the film is easily compressible.

Many thanks to everyone for their comments.

NP, glad everything worked out well. :)
