Your .tpr project

Check your paths. Make sure they are short, and reset your "source range"

and make sure you set the path to TMPGenc after you fill in everything and stuff. that's how i messed up before.

I too have had this problem.

I have ran CQMatic on several movies, but each one gives a final CQ of around 89

Is CQMatic set not to go above 90

I prefer high quality video over single CD encodes, so choose to make MPEG-2 KVCD's on multiple discs. I encoded The Watcher (92 mins) and Memento (110 mins), both to fit on 2 80min CD's. Both gave the same final CQ of 89.63

which of course gave me a file size for The Watcher well below the 1600 Mb (including audio) expected.

I have to say that at present, I haven't had a great deal of success with file size prediction in CQMatic

Is it not designed for predicting MPEG-2 over multiple discs

Having said that, I am well pleased with the final quality of the resulting discs, which have a quality, IMO, equal to the source DVD

Any ideas on how I can get the prediction right and therefore squeeze a little bit more out of the encodes

Kwag...maybe allowing CQMatic to go above 90

I've just noticed 'fix' to latest version 1.2.02. Kwag.... how about an override switch a la Override Default CQ

Thnx for the link, I'll certainly give it a try, but my problem was with the file size being too small not too large

I was therefore hoping to be able to up the CQ slightly to get a larger file, but with CQMatic stopping at 89.77, (or whatever), how much to up the CQ by would still be guesswork.
