another source Krassi?
but i only have musicals and Disney's... all ntsc.
and your results will be great for everybody in the forum!

Kwag, i'm stuck :roll: :
I have processed the same source, with the same settings on two differenct PC's. The only things that could be different, are the Avisynth version and/or the Mpeg2Source-plugin 8O
Thats the log on the other machine:

@ Krassi...
better is stay with "the matrix".
have big size time and is one good reference....
"everybody" but me have this movie too!

:screwy:
think how the posts will be strange with Disney's....like:
"hey,dumbo is hard to encode,is heavy and break the system....or
pinochio nose seems "strange"....or
in white as snow...hey it's anamorphic?...the dwarfs are small."
things like that.

I love the "Lebkuchenmann" (is gingebread-man right?) in Shrek when he squeals the muffin-man :!:

@Kwag:
I'm doing a prediction right now with 1.1.04 8)
I can compare my Avisynth-versions this evening.

EDIT: Just found it:

Lord Farquaad: Tell me where the creatures are!

Gingerbread Man: All right, I'll tell you. Do you know the muffin man?

Lord Farquaad: The muffin man?

Gingerbread Man: The muffin man.

Lord Farquaad: Why yes, I know the muffin man. The one who lives on Drury Lane?

Gingerbread Man: Well�she's married to�the muffin man.

I've just played around with the average bitrate. I've used valc 0.0.5 to get the average bitrate. Moviestacker suggested a value of 726 kbps, vcalc 717.
Then i've set MS Precision to 0.71 and here are the encoding results (712 kbps) :mrgreen:

Thats the best prediction i ever had.
@Kwag:
Maybe you could implement the bitrate calculator before version 2 or release version 2 now :lol: :?:

I think the prediction problems aren't coming from CQMatic 8)
Maybe we should take a look at calculation of the average bitrate.

Was there something different :?: MIN, MAX :?:
There shouldn't be any difference with the same settings from 1.1.07 to 1.1.08b :!:
You should get about the same CQ, but only two decimal points instead of four on the latest version.

Krassi

08-11-2003 09:41 AM

I changed Min. bitrate to 400 and gave CQMatic another average bitrate (702 instead of 712).
I've seen your calculation of Bitrate and min bitrate in another post and tried it.

kwag	08-11-2003 09:44 AM

@Krassi,

Could you try identical MIN, MAX and average with 1.1.07 and 1.1.08b, and see if you get a different CQ :?:
There shouldn't be a difference 8O
