beta 6 test :

5 tries, then he found a cq of 51,50...
encoded same movie with 57 as cq, filesize (only videostream) was ca. 840mb i think , instead of 685...so the cq could go right!

donīt have the bug with the loop

yes i have pal (germany)

well, beta6 gave me a cq of 51,50, whichs seems to be realistic , but manually i got an cq of 54, well must check it...

will test beta7 with shorter movies to get faster results, which i can post :)

jorel 07-24-2003 08:57 AM

with versions 1.0b6 and b7 the CQ increase from
CQ63,10 to CQ63,62 ,just the same final prediction for each.

remeber,i got perfect final size 290mb with CQ63!

Hi Jorel,
great results. How many tries does CQMatic need to find final CQ :?:
You post your results sooo fast 8O
Mine takes about 5-10...

running 9th at the moment and still not finished. Maybe because of the short video length.

Yes. What are the CQs being shown :?:

Krassi 07-24-2003 09:16 AM

60, 57.38, 56.07, 55.41, 55.08, 54.92, 54.84, 54.80, 54.78, 54.77, 54.66, 54.66....stuck again.

I'm offline now, sorry. See you tomorrow :D

jorel 07-24-2003 09:22 AM

my sample is short and i got the result after
CQMatic search only 3 times for final prediction.

:!:

tigger 07-24-2003 09:30 AM

well as i can see now, beta7 is giving me a LOWER cq then beta6 :?: :?:

tigger 07-24-2003 09:34 AM

beta6 : 51,50
beta7 : 48,18

Your CQ should be no lower than 0.25 difference from previous :!:
So if your last CQ was say 62.50 and your current is 62.74, your final CQ is 62.50
Does that difference match your predicted CQ values. It has to :!:

found sth in tmpeg, the aspect ratio was another then in the test with beta6!

testing now with THE EXACT SAME settings like beta6...

perhaps this was the reason why my filesize was always much lower then i expected and wanted?

íīll do a couple of tests now...

That's weird :!:
It should have stopped after 55.08, 54.92 because Abs( 54.92 - 55.08 ) = 0.16 which is below 0.25 (the trigger point) and encode at 55.08 :roll:
I'm encoding something now to verify this. Unless my Abs (Absolute value) is screwed up :!:

tigger 07-24-2003 10:11 AM

my result :

beta6: 51,50
beta7: 51,18

now EXACT same settings, so with another aspect ratio, i got a lower cq (perhaps the reason of my problem with my filesize?)

well, will take this cq now, and encode it as 16:9...
