DVD Rebuilder and CCE Customized settings

[tompika]

I'm just wondering which version of CCE and what settings you guys use and why

VBR_Bias controls how CCE distributes the bitrate. During the first CCE pass, the bitrate is distributed to achieve constant quality. The bias determines how much weight is given towards keeping that allocation. High values prevent high bitrate fluctuations in between GOPs, and low values give CCE more freedom to use bits in highly demanding areas.

VBR_passes indicates the number of CCE passes. This has to be 2 for CCE Basic. For all other CCE versions, note that if you use X passes when setting up CCE manually, enter X+1 here as CCE SP does not count the creation of the vaf file as one pass.

Quality_prec corresponds to Image Quality Priority in CCE 2.50, and Quantizer characteristics in CCE 2.66/2.67. The value ranges from 0 - 64 (as in CCE 2.66+), but is scaled to 0-100 when using CCE 2.50 (so if you're a CCE 2.50 user and have set this parameter to X, you have to enter X*64/100 in DVD-RB). This setting determines if CCE gives priority to image details, or evenly colored areas. The lower the value, the more priority will be given to details, which could result in blockyness or banding in other areas. A high value will result in good looking evenly colored areas, but could result in edge artifacts.

I use

VBR_Bias - 10
Quality_Prec - 24
VBR_Passes - 3

I use VBR_BIAS 10, QUALITY_PREC 24, VBR_PASSES 2. I use CCE version 2.60. I used those settings from a guide I read. So far the backups I've been doing are great quality.

Each DV source differs, so a fixed setting may not be best for everything.
However, from what I have read, some general rules of thumb could be:

Quality_prec set for between 27-30 when avg bitrate >3000

VBR_bias should be set for 40-50% of Qual_Prec level, or... more generally:
movie <2hrs - 23-25
movie>2hrs - 15-23
movie is 3hrs+ - 15-20

I have my DVD-RB set to "one Click", but the Qualtiy Setting window keeps poping up while encoding. Does anyone know why this is? TIA
