Why do I say I made a "semi-manual" prediction ? In fact the
automatic prediction of D2S is also screwed up by the MA script.
D2S did a first try at 70, then go to 74, then 75, then 82, then 68... !!!

I saw in the log that at 75 the results where very close to the final
size wanted. So I stopped the process, did a "recover" and this
time I set the CQ to "fixed value" of 75.

Everything went perfectly.


I followed this *exactly* and ended up with 2 files :) One large one and one small 32 MB file. Perhaps I did not select my static CQ low enough (it was 20).

20 ? 20 !!!

Oh my god ! I think you should lower the resolution and use VCD one. And lower also the max bitrate to 1600, and use an audio rate of 112. And finally think about using a 90min CD (you can put 912 Mb on it, 100 more than on a 80min !

With so low CQ the result will be unwatchable !

The resolution is a 352x240 encode of a full screen movie. And yes, the Max bitrate is set to 2000, but according to Birateview, it does not go above 600. It is a 160 minute movie.

As a followup
 
I am using VCD.

Honestly Thomas, 160 min is BIG. Why don't you use a CD90 ?
Did you try to watch the result you already have at CQ=20 ? I don't think it's worth the cost

Yes, I burnt the CD and played it a few hours ago, before coming in to work. It's slightly less than the quality of a commercial VHS tape I would say, hence in my opinion, watchable :) Now, I've also made 120, 90, and ~76 minute DVD -> KVCD rips and they look very good, extremely good and perfect in turn (again, from my limited perspective).

Using CD90's will happen down the road as soon as I've been able to 'master' D2S and CQMatic, and this whole procedure :lol:

Realistically, I will be using CD1000 as my CD size, since I will be placing these movie backups onto DVD and watching them in file mode.

thanks again for all your help.

Tom
