can i got adjusts to CQ 100 ?
 
hy Kwag,
please,only you can answer this:

can i change some line in CQMatic to got the max CQ if needed :?:

i'm encoding for 2 cds and using audio bitrate from 160 to 250,
and it will give me CQ from 90 to 100!

thanks in advance!

:)

answer to "your question":
my question is clear...!

for the reason that i ask...,
just the reason that you answer:
i want more than CQ90 to encrease the final size cos
will let left more than 100mb in some cases in each cds.
oh....when you think in audio size/bitrate:
yes, i have 100mb free using audio at 320-48k in each cd.

again......how can i change some line to got the max CQ
prediction between 90 and 100...
:arrow: IF NEEDED :?:

:roll:

You can't.

can't Phil?
8O
maybe is possible.


Kwag.....help.
a months ago ToK sometimes encrease the CQ to 100 and after hedix
change "something" in the program,put the limit to CQ 90!
CQMatic work like ToK?
of course have a way?!?!?!

:?

kwag 09-01-2003 12:11 PM

It's set as a MAX of 90, because there's no more visual quality gained over that. It's a waste of space going over 90 :!:
Use the extra space left to increase your audio bitrate ;)

As you tell Jorel : Hedix has changed something. The designer of the program. Not you, not me, not anyone else. Only Kwag can do it for you :-)

If I enable CQ finding between 90 and 100, it might take another 5 to 10 iterations to find CQ, because of the non-linearity of TMPEG :!:
I don't think anyone wants that :roll:

jorel 09-01-2003 05:16 PM

ok,ok,
like Avalon wrote,like phil wrote, like kwag wrote!
i know my friends!

:arrow: now please,listen to me:
using audio bitrate 320 at 48k and CQ90 i have
:arrow: 100mb FREE in each cd :!:

IF the prediction could give me more than CQ90,
something between CQ90 and CQ100
i will use this FREE space to encode the video cos
i can't encrease more the audio...is in the max bitrate!

:lol:
yes,i know!

please Kwag,
is possible?

ps:
my english is very horrible.
for me ,i'm only repeating the same question in the first post.
:? :?
only observations...not important!
:wink:

Yes, but why would you want to add 100MB of data, which is not useable :?:
You won't see any better quality, so you're just filling 100MB of data that won't be used for anything :!:
And the time spent to find CQ between 90 and 100, will cost a very long time :!:

jorel 09-01-2003 05:34 PM

i know how you're "feeling"!
:lol:
seems "stup" but i want it cos i'm thinking "strange ideas"...
i can't explain it now...need tests.
if this ideas works will be great for me.
the very long time to find the CQ value isn't important for me,
i can wait!

:lol:

Kwag,
if is easy,please help me,
if is hard for me(not for you) to make it, then forget!
:wink:

Kwag send me a "very special CQMatic private version".
is called:

and the best is:
:arrow: Goes up to CQ=100 :wink:

see the first log after find prediction for small sample:
