How does it do size prediction?
I just used CQ / CalcuMatic for the first time. Works great on getting the right CQ Value, however... it varies from movie to movie.
I did a test on 3 different DVD's. 120min KVCD TMPEG Template 352x240 First was "Best of Mike Meyers - Saturday Night Live" 83 mins. Inverse Telecine / 23.976 fps. 1.33:1 Aspect CQ Matic made the file too big. About 850megs. 2nd "Lord of the Rings - Extended DVD Edition 1st Disc" 104 mins. Film / 23.976 fps. 2.35:1 Aspect CQ Matic made the file too big. About 900megs. 3rd "Fight Club" 139 mins. Film / 23.976 fps. 2:35:1 Aspect CQ Matic made the file WAY too big. Almost 1500megs. So, I guess, after reading in the forums, everyone seems to love this program, and it works wonders for them. What am I doing wrong? And does someone have a guide? |
Your third attempt is very strange. CQMatic has accuracy problems (due to the way CQ is managed by tmpgenc in fact : the curve is not linear that prevents any 100% accurate prediction) but not so much !
A good policy is to use an audio bitrate for the prediction a little higher than the one you really plan to use (160 insteed of 128 for instance). |
CQMatic is a good tool and use it often. I alwasy take of 0.2 of the predicted CQ and the size is 10mb less or more, then i do something with the audio.
