Hey Sharktooth very nice collection with EQM series. My favorite is Eqm V3HR modded for standalone support. I was just wondering is Trellis bug fixed or do I have to use these two workarounds?
1. Disable Trellis or 2. Restrict quantizers to 2-31 I'm using latest Jawors Xvid 1.22 VAQ version. Last edited by SilaSurfer; 23rd December 2010 at 18:30. |

Hey,
Right now i'm using xvid-encraw from megui development server. The aim is to backup bluray content to view in players which not support it. So i'm encoding bluray to xvid HD 720p and bluray to xvid SD 480p. I load to xvid a small avisynth script with DSS2, spline16 resize and a little bit of sharpen. I've been in research for the best xvid options to retain the most detail without blocking and without loosing standalone player compatibility. The above taking in consideration that 480p is to be encoding at a max of 2000 avg bitrate and 720p at a max of 3000 avg bitrate. The settings i'm using now are: 2 pass, 2 max b frames, bframe ratio 162, bframe offset 0, VHQ for bframes and mode 4, MSP 6, no QPEL, no GMC, Chroma Motion, Closed GOP, Trellis Quant, Adapt. Quantization, Packed Bitstream, No Turbo, max kframe in 240, min qt 2 max qt 31 So now what is missing is the custom matrix... What CQM would you advise with all the above set? (also if you suggestions on other used settings please don't abstain ) Thanks for your help! |

I know that. I misunderstood what Sharktooth meant by his workarounds on the first page of this thread. The bug came when you would use Trellis + EqmV3HR matrix with quantizer ranges Min 1-31 Max but I never use that so. I thought that restricting max quantizers would show those issues. Thanks and I apologize for taking your time.

Is it 720p or 480p @60fps or 30fps?
If you use a good denoiser, QPel can help 480p encodes. Avoid the old AQ.... grab a new xvidcore.dll and use the new VAQ if u need to. I seem to have read somewhere for best standalone player compatibility, we should use max one consecutive B-frame with "Packed Bitstream" on. If it is a newer player supporting 2 max cons. B-frame, turn off "Packed Bitstream". QPel + 2-max-cons-B saves over 10% bitrate (for more movie details). max key-frame interval is still 10*fps. But for 60fps encodes I think we may reduce it to 5~7*fps. H263 with new VAQ offers the best standalone player compatibility and it encodes fastest too. If u want more details, u can use EQM-v2 or EQM-HR-v3-SAP-mod. Make sure that u do have sufficient bitrate because VAQ makes them more prone to blocks and rings for frame peepers. (Actually, H263+VAQ tends to give running textures @ insufficient bitrates too.) |

Well, my standalone player don't support QPEL so i cannot use it. Hum.. could you explain me what really packed bitstream does? Because, until now, i've always used it because virtualdubmod doesn't show image if i turn packed bitstream off. Well, for now, i've been using sixofnine HVS with VAQ and it seems to have good results, however, i can't find those matrices you said. Would you help me? Thanks a lot |

EQM matrices? Take a look at Sharktooth's signature.

I've got an artifact by using eqm v3hr matrix. You can see it in the right top corner.

It's highly improbable a quantization matrix can result in such an artifact unless the encoder and/or the decoder used is buggy.

".... on a sidenote eqm v3 ULR is obsolete since LCD displays. ...." (You can still compare it with Jawor's 1CD matrix and see which one looks better for you.) |

At what compressibility level did you notice EQM-v3HR + VAQ to show blocks and ringing? I still use Xvid when it comes to SD material and this is my favorite CQM. I was thinking of using VAQ instead of my general setup where I restrict quantizers. I think VAQ should provide more fine quantizer distribution. My compressibility is very low. With compcheck <90%, bitrate range 1800 to 2400. |
