Ok here is the thing i want to experiment with CQ_VBR and low Resolution, Now my is manual prediction is accurate with CQ_VBR I know that the video ini on tok to VBR_Auto will change tok to use that mode, but dont know what to do to chainge the Max n min. bitrate and the CQ_VBR from 100% to a lower value. Any clues anyone

Hi ovg64,

Try this, with either CQ or CQ_VBR on KVCDx3 528x480.
(1) Set the MAX bitrate to 2,000Kbps ( No need for a higher value if you are using the MA script. )
(2) Set your MIN bitrate to 50% of average bitrate required ( look it up in MovieStacker ). If 50% is below 300Kbps, then leave it at 300Kbps
(3) Now run prediction, and see how close your end result is

Try to use "Full" prediction, instead of "Fast" prediction.
Let me know your results ( I'll explain the details later, when I'm done )

OK, used Tmpeg 2.58
Full prediction (loooong)
max. 2000 kbits/sec.
min. 945 kbits/sec. (50% of average 1889)
tok logs

NO WAY average 1889
There's no way you get an average of 1886Kbps for a movie of 01:49:46 on one CD
Check your settings again.

Moviestacker 1st tap
Video Stream
Average kbps> 1889

1889/2=944.5 ~ 945 this is what i used

Edit: Dammmmm shhhh had it for 2 CDs no wonder

Average kbps 888/2 = 444 kbps Sounds better

let u know later homes

That's exactly what I thought Exactly

k there u go should had started at 60% now i forgot what i was doing this for

I pm the results kwag; and answering my own i was able to make tok to do prediction with CQ_VBR by chainging the following lines in the video ini,


*Job.MPEG.Video.RateControlMode=MPEGVideoEncoder_R ateControlMode_VBR_Auto
*Job.MPEG.Video.AVBR_Quality=60
*Job.MPEG.Video.AVBR_MaxBitRate=2000000
*Job.MPEG.Video.AVBR_MinBitRate=300000

I couldn't get tok to chainge the bitrate using the tap so i made the chainge straigh at the video ini. now i want to experiment with some
352x resolutions.

EDIT: dont bother with what i post above, tok just hangs at 60%....
