hi,

i try to edit the divx4 and divx5.log file for increase the quantizer used for the end-credits.

exemple u make a divx5 2pass encode at maxQ : 10 minQ: 2 , bitrate 900kbts, total frame : 10000 endcredits start at frame : 5000

anfer the first pass , edit the divx.log file , go to the frame 5000 and change the quantimizer to 16, i think it's a good idear but i don't have enought knowledge in the divx.log file structure, perhaps someone can explain me what i should change to increate the quantizer.

after some test it seems to me the more important parameters it the complexity

exemple : MaxQ6 minQ2 :
-----------------------
Frame 0: intra 1, quant 6, texture 105155, motion 0, total 105155, complexity 3286093
Frame 1: intra 0, quant 6, texture 21511, motion 1141, total 25494, complexity 672218
Frame 2: intra 0, quant 6, texture 31025, motion 1252, total 34890, complexity 969531
Frame 3: intra 0, quant 6, texture 14882, motion 943, total 17907, complexity 465062
Frame 4: intra 0, quant 6, texture 24611, motion 1067, total 28244, complexity 769093
Frame 5: intra 0, quant 6, texture 19823, motion 1092, total 23347, complexity 619468

exemple : MaxQ16 minQ16 :
-------------------------
Frame 0: intra 1, quant 16, texture 43760, motion 0, total 43760, complexity 21879998
Frame 1: intra 0, quant 16, texture 3304, motion 651, total 5320, complexity 1651999
Frame 2: intra 0, quant 16, texture 6128, motion 959, total 8832, complexity 3063999
Frame 3: intra 0, quant 16, texture 3302, motion 653, total 5185, complexity 1650999
Frame 4: intra 0, quant 16, texture 4088, motion 657, total 6166, complexity 2043999
Frame 5: intra 0, quant 16, texture 3406, motion 722, total 5539, complexity 1702999


should i only increase the complexity or the texture and total figures are important ? personnaly i think the only important value it the complexity (more highter => more compression) and the other value are not important , perhaps someone can explain me how to find the solution.

thanks :)

Ps: sorry for my poor english

The only thing that may be usefull to change is the complexity, lower value will provide more quality and vice versa

It would be much simpler and faster to just do it the way gordian knot does it split credits off and single pass constant quant them and then 2 pass the rest.
