Doom9's Forum - View Single Post - [TEST] Rv9, Divx 51, H.264 R-D Plots

Ok guys,

I did some tests using the VQEG 'Mobile & Calendar' sequence. I deinterlaced it using Tom's MoComp, converted to YV12, and cropped it to 720x480. I encoded using all the slowest settings with all pre/post processing disabled. Each video followed the GOP structure IBPBPBP...

Target Bitrates (k): 256, 512, 768, 1500, 2000, 3000, 4000,6000

Divx 5.1 2-Pass , slowest, no PyschoVisual

RealVideo 9 - 2-Pass, CBR, encoderComplexity=100, noisyEdgeFilter=false, MSL=60, patternAdaptivity=1, scalingFactor=20

H.264 - JM 6.1e, 5 Reference frames, CABAC, R-D on, Hadamard on. Since no rate control exists, Iframe QP = Pframe = Bframe QP - 2 (about 20% larger step size)

I would love to include WM9, but I don't know of an easy to way to perform command line encoding to ease batch encoding.

I am trying to keep this a fair comparison as possible, so please feel free to posts any questions, comments, and suggestions you might have. I will be posting more data as soon as I have it.
