How can I unleash Xvid quality for 7 CDs?

Hello, friends, Perhaps my question is a bit crazy, but I'd like to know the best parameters for using Xvid to convert a DVD to the maximum quality disregarding the number of discs used. May be even equal to the DVD size, just for curiosity, say 7 or 8 CDs... My actual settings don't go more than 3 CDs, on most films, they are here: ================================================ 6 ultra high MPEG XVID 1-mode decision 300 1 Use chroma motion Quarterpel 2 150 100 0 DX-50 B-VOP compatibility Quantization: 2, 31, 2, 31 DEBUG: Chroma optimizer On the 2 passes... ================================================== NOTE: It would be interesting if we could raise the size of the file, but could improve the quality also. raising only the size of the file don't have any sense from making them on 2 CDs only. thanks in advance, Dihelson Mendonca

If you want maximum quality, and the filesize doesn't matter, simply use 1-pass quantizer based encoding mode with quantizer 2. Of course set bframes and qpel off. No need for 2 pass for this. EDIT: quantizer 1 is overkill. Don't listen to Acaila! :D

At higher datarates more accurate custom matrices help. (search the forum) Cu Selur Ps.: Here the custom settings I use atm for high bitrate captures: IntraFrame-Matrix _8_10_11_12_13_15_16_16 10_10_11_13_14_15_17_18 11_11_13_14_15_17_18_21 12_13_14_15_17_18_21_22 13_14_15_17_19_20_22_26 15_15_17_19_20_22_26_28 16_16_19_20_22_24_27_64 16_19_20_22_24_26_64_128 InterFrame-Matrix _8__9_10_11_11_13_13_16 _9__9_11_11_13_14_16_16 10_11_12_13_14_16_16_21 10_12_13_14_15_17_21_27 12_13_14_15_17_20_27_32 12_14_15_17_20_27_32_34 15_15_18_19_27_32_34_72 15_18_19_27_32_34_72_144

Speaking about quality - okay, i set the MPEG-Custom, but where to set the "HVS Best matrix"...??? :rolleyes: Pls, help.

@Selur: yea I've tried mftoon, but I didn't need it for this. I had a very very nice quality dvd. I thought about using a custom matrix, but I know I read somewhere on here before that custom matrices don't comform to mpeg-4 standard, and I don't want to create a file that might not be supported in the future.

Instead of Huffyuv I would take one of the lossless codecs that supports Yv12. Avi=>Mpeg works fine with TmpgEnc and with the doom9 guides it should be no problem to da an avi to dvd conversion. ;) "and please, continue to discuss this" we probably will ;) Cu Selur

Another thing about quantizer numbers in Xvid and DivX: If you don't use the same matrix you can't compare the quantizer numbers. e.g. quantizer 2 with mpeg is something like six or seven (if I remember correctly) with 'my' matrice Since in general the h.263/mpeg quantizer 1 used in Xivd turns out to be 'unpredictable' large it doesn't seem to be a bad idea to disable it for 'inexperienced' users. (If one needs more 'exact' quantizers change the quantizer matrix.) Cu Selur
