Good morning all:

OK, these are my results:

[[quote]quote][quote]
Quote:
kwag's formulas:
Quote:
Video stream needed: 720 MB
Audio used for calculations: 90 MB
Avg bit rate: 1337
Moviestacker numbers:
Quote:
Video stream needed or target: 708 MB
avg bit rate: 1305
CQmatic settings:
Quote:
Version 1.1.07
Length of film: 75 minutes
Average bit rate used: 1337 (From the calculated numbers)
Tmpeg settings:
Quote:
Avi input (d2v from dvd2avi)
Max bit rate: 2000
Min bit rate: 768 (it should have been 763)
CQ used 67.7058 (CQmatic)
Now the final result:
Quote:
Endoded file size: 700.697 MB
Time to encode the avi file: about 6.5 hours
% to calculated numbers 2.681%
% to Moviestacker 1.031%
Please note that if I would have used the proper bit rate, the resultant would have been different, and perhaps closer to the target number.
I am going to proceed with this test and create the kvcd!!!!!! The final kvcd will have the proper average bit rate....
Will tell you about it later on

I am very sorry, I did not mean to taint this thread, I meant to place my results in a different thread, (testing CQmatic versions) perhaps kwag can do that for me.

Sorry

@Krassi,

Run DVD2AVI and load your VOBs. Tell me if on the preview window, your source displays as 4:3, even though the movie is 16:9 wide screen :!:
That's what I've found on my movie that fails. On the ones that display 16:9 and are actually wide screen 16:9, the final size is always on target.

Hi Kwag,

DVD2Avi shows 16:9, the movie is 16:9 (2.35:1).

Hi Krassi,

As you have a very fast computer :cool: , could you try something :?:
Do two predictions with CQM with Scene Change "Checked", one with 1:1 VGA, and another with 16:9 PAL. See if you get a change in predicted CQ :!:

Sure :D
I'm currently testing with 16:9 PAL, then i'll change it to detect scene change and post the results :P
