Hi All,
I've basically followed the guide by black prince and get a low quality output (Nothing like the sameple KVCD File) and an oversized file (894Mb) instead of one that will fit onto an 80Min CD-R. When I run Movie Stacker V2 ß3 I get it to load the KVCDx3 template and include Field Deinterlace and leave the defaults.

When I run ToK I get the following error appearing in TMPegEnc:
Sampler: samples must be >=2
(D:\temp\ToK\video.avs, line 30)
until the actual DVD file gets encoded into MPG format. In myBBMpeg log file I get HEAPS of Video PTS entries such as:
video PTS (21584.00ms) underflow at pack 2911 by 17629.33ms. I can post the rest of the log (Without the PTS lines) if it will aid in the diagnosis of why my KVCD's are not working properly.

Thanks in advance.

Can you post the avisynth script that you generate with MovieStacker ?

I guess you have "Sample()" at the end. If yes, remove it.

Hi Dialhot, you guessed right, Sampler is at the end... I'll try without it tomorrow and get back to you (This takes about 8-9 hours to process)

#================================================= =====#
# -= AviSynth script by MovieStacker v2.0.0 (beta3) =- #

LoadPlugin("D:\Program Files\MovieStacker\Filters\UnFilter.dll")
LoadPlugin("D:\Program Files\MovieStacker\Filters\LegalClip.dll")

That will fix the problem of "Sampler: samples must be >=2". In fact Tok adds a Sampler() itself, so what you did there was a sample of a sample )

So by sampling a sample, I'm in effect sampling nothing??

The way that I created the script was purely with Movie Stacker, I loaded up the KVCDx3 preset and told Movie Stacker where the video file was... So why does movie stacker add something that isn't required?

Nearly nothing. Thats why you had this error. Just let ToK or CQMatic do the prediction.

It was/is useful with manual prediction, thats because it was implemented. Just get rid of this line by deactivating it.

You have the perfect example that show why Tok is out of date and why Kwag uses all his time to develop CQMatic : the prediction is very hard and very random with the last optimal script. That's very sad...
