I am backing up the best of friends on the lbr template. This is the first time i have used the sampler method. This is just my script if there is any confusion if i am doing it wrong.


LoadPlugin("d:\encoding\mpeg2dec.dll")
LoadPlugin("d:\encoding\fluxsmooth.dll")
LoadPlugin("d:\encoding\GripFit_preview.dll")
LoadPlugin("d:\encoding\blockbuster.dll")
LoadPlugin("d:\encoding\legalclip.dll")
LoadPlugin("d:\encoding\sampler.dll")
LoadPlugin("d:\encoding\convolution3d.dll")
LoadPlugin("d:\encoding\dustv5.dll")
LoadPlugin("d:\encoding\decomb.dll")

Mpeg2Source("D:\friends2\bestoffriends\vts_011.d2v ")
legalclip()
GripCrop( width=352, height=240, overscan=1, source_anamorphic = false, dest_anamorphic = false)
GripSize()
#PixieDust()
#SpaceDust()
faerydust()
Convolution3d(preset="movieLQ")
Blockbuster(method="noise", variance=.5, seed=1)
GripBorders()
LegalClip()

I get a sample of 4290 frames. So from this i use the method Predicted MPEG size = (( Total frames/MovieTimeInMinutes) / 24 ) * MPEG sample file size. The movie is 257240 frames and 143 minutes long. My ideal test file size should be 9.74 mb. When i achieved that value i ran tempgenc and encoded. The final file size was 660 mb instead of the 730 i should have. This is using the new templates, so let me know if missed something or if i am doing something wrong which i think i may be doing. Thanks

You missed something... it is what they called "factor".

This varies... some uses.. 0.95 and some uses 0.98...

so it should look...

Predicted MPEG size = (( Total frames/MovieTimeInMinutes) / 24 ) * MPEG sample file size*factor

I hope this helps

Thanks i wasnt sure if this applied to new prediction factor or not. I always did it on the other prediction method. What is the recommended factor for this one? It didnt mention the factor in the prediction tutorial. Well thanks for your help.
