do you know why this is so?
should i use cdr 90 in moviestacker to get the avg bitrate, so it will fit to 80min cdr?
or is it a little bug in cqmatic (what i can´t imagine :) )

thx :)

Because it's a BETA version :mrgreen: No, just keep the settings as you normally use them.
But please, when your encode ends, let me know the difference of the encoded video size and the one Moviestacker required :!:
Also, are you encoding NTSC or PAL :?:

Make sure you look over all the settings on the 2nd tab (audio and stuff) of moviestacker. I think it defaults for 160kbps audio, where maybe you planned on encoding at 128. And if you're muxing with bbmpeg make sure you select that and also MPEG-1 if that's how you're encoding. All these little things will affect the average bitrate on the 1st tab so make sure you set those parameters correctly! Don't forget to check whether you want 1 or 2 80min CD-Rs.

Once you have the correct avg bitrate, use this to calculate the MIN and MAX bitrate in tmpgenc (under CQ settings). You want to set your MAX to 2000 and your MIN to 0.57*(avg bitrate). And THEN save your project file for loading into CQmatic. I think doing all that will help make your prediction more accurate!

Good luck.

well, once again i tried to use a 57min movie with cqmatic, but without success :(

i also used .avs to load it in tmpeg, but it gives me a cq from 1 again..:(

tell you later about the encoding file sizes from video :)

bye

here what cqmatic says :

movie time : 54
avg bitrate 1854
pred. mode only
sample size 15113.93
executing pred. phase...
using cq of 50
encoder started
encoder end
difference = -1.5476664.000000
CQ BELOW WATERMARK set to
Using CQ OF 1.00
ecoder exited...

hope this helps to find a bug or sth...

Of course :!: :imstupid: :oops:
It should have been: 1.5476664.000000 (No sign)
Get the file again.
Same version, but BETA 2a (Fixes the above ;)

Thanks :D

hmmm
sorry but the error is still there
doen´t do any file size preduction now , log :

execute
movie time 55
avg bitrate 1800
full encode mode
prediction phase...
using cq value of 65
encoder started
encoder end
encoder set to full encode mode
full encode start
encoder exited
encoding complete...

sorry :(

IT DID :!: "encoder set to full encode mode"
Isn't TMPEG now running full encode, or you never saw TMPEG :?:

-kwag

well...
tested it once again, set CQ value to 10 !

but once again, he did 1 prediction with 10 as cq, then he started directly encoding with cq=10, but that´s not possible!
the movie got 55 min or so :)

tigger did you make sure that you reset clip editing (via source range) in tmpgenc? and that source range was unchecked before saving your project file? That's screwed me up a couple times when testing cqmatic out.

yes, i´m always checkin these points...

tested it with cq value 20 now, same again, 1 test with cq 20 and after that directly encoding with cq 20, without setting it up ...

@Kwag,

Tested "Monsters Inc" (min=92, ave birtate=1079, 1cd) with CQmatic
file prediction of 85.56. Chose audio of 112kbs size of 87mb. The
video file size is 716mb + 87mb audio = 803mb. WOW!!! :D that's
excellent prediction. Going to try "Gangs of NY" (min=167) on 2 disc
for 2 cds. BTW, Monsters picture quality is awesome :D

Hi bp,

Make sure you use BETA 2a ;)

-kwag

bp, what were your settings in moviestacker?

kwag, here my results of encoding :

video file size is : 639 mb

audio file size : 89 mb

= 728 mb , although i set moviestacker to 80min cdr.

well gonna try another one...:)

hey bp,

I'm doing that one now- 2 cd, 528x480, 128k audio, MA script, avg bitrate 1062; CQMatic predicted cq of 64.44

6 hours left to finish encoding ;)

ren

@Kwag,

Got it before trying "Monsters Inc" :wink:


@tigger,

I paid careful attention to settings in tab2 of Moviestacker and as a
result average bitrate increased from 1075 to 1079. This made the file
prediction more accurate :)


@rendalunit,

Just started "Gangs of NY" will report file size when done. Eventually
want to try KDVD for multiple movies using CQMatic to estimate how
many will fit using 704x480. 8)

-bp

CQMatic Version 1.0 BETA 1 is out :mrgreen:
(Get it at the top of this thread)

Have fun :!:

When setting up TMPEG what should the CQ be set at?

David

I usually start at 60.
