Used Qmatic for first time (RC-3). Starting with CQ of 60 it took 50mins to find CQ of 71. Some relevant stats:

PAL DVD movie: da Hip Hop Witch (interlaced)
Avg. bit rate 1158
Movie Time 85
Max/Min rate used in Tmpgenc(v2.511) 2000/660

Length of .mv1 = 818,325kB. Should have been 716MB

Used MA script with Deinterlace. I also use idct=5 in Mpeg2Source().

Any ideas anyone?

hi Kwag..

Yeah, I was wondering WHEN you was gonna get to that hehe :lol:

-vhelp

well, think i got the clue :)

encoded film 88 mins,

set min = 0.57*avg bitrate, max=2000, predicted cq with cqmatic,
set min to 270, then encoded the movie with the predicted cq, video stream length = 699mb, after muxing : 790 MB !!! SO PERFECT!!!
THX KWAG FOR THIS GREAT TOOL!!! :) :D :D :D :D

Great to hear that tigger :D
Your source was DVD right :?:

-kwag

yes, pal dvd
friday the 13th *G*

Please don't forget.........
 

Todo:
* Continued testing higher degree of prediction accuracy.
* Add user precision selection. (For version 2, if necessary )
* Add log file on disk [ Log now copied to Clipboard ]
* Avoid multiple running instances on CQMatic.
* Shutdown after completion. (For version 2 )

Please don't forget the bitrate calculator w/ specified output size for us DVD fanatics.

( I realize it has lesser priority )

Re: Please don't forget.........
 

:oops: Sorry, I forgot to put it on that "todo" list, but it's in the list for version 2 ;)
I'll edit that post now :!:

Edit:
Added this to the list:
* Integrated Bitrate Calculator with CD, DVD and user specified target sizes. (For version 2)

Great! Now that you have a Cyberhome, I think you'll like playing with CDVD.

:idea: Maybe with CKDVD :mrgreen:

Would you believe that is what I've been putting on my labels for quite a while now? It seemed pretty logical to me!

Good result tigger. One that I hope to emulate. I'm a little confused. Do we set MIN = .57*avebitrate for prediction purposes then resort back to a different MIN for the encode?

ozjeff99

no my friend,don't back,
use the result of the formula.

:wink:

CQMatic Version 1.0 Release
 

Version 1.0 Released :!:
(Top of this thread) :cool:
Now give it a whirl with DivX, XviD, Interlaced, Progressive, or any sources you can throw at it :!:
Please let me know your results :cool:

hi Kwag..

I know.. I'm up late..

I'm having some problems w/ your latest update..

Now, it's giving me this error message:

-----------------------------------
For encode mode, 3:2 pulldown when playback can not be used if the flame
rate is not 23.976fps or 24fps.
-----------------------------------

* TMPG v2.53
* Movie: "Dogma"
* 128min
* Ave bit: 733 (my calc)
* min bit: 418 (my calc)
* frames: 184,135.68

Question:
* are you setting up your temp .tpr files for MPEG-1 ??

Thanks for any assist,
-vhelp

jorel, when i use the min bitrate from prediction, i don´t get good results, well files too big, files very too small...

when i set it back to a different min, to 270, everythings works fine...
can´t explain why...but now i´m fine with cqmatic :)

Hi vhelp,

I don't modify the user .tpr. I create a copy of it, and modify the relevant parameters for prediction only.
Have you tried to load your .tpr after saving it, and click "Start" on TMPEG to see if you get any errors :?:
If it loads fine in TMPEG, and starts encoding without errors, then it should also run fine when CQMatic loads the .tpr.

@ Kwag..

Ok, I think I may know what the issue(s) are..

1 - I have an older version TMPG (v2.53 to be exact) and,
2 - some of those .tpr source syntax may not be availble in MY version.

So, what I'm going to do is try another TMPG version (higher) if I can find
any on my hd that I D/L'ed previously.

Sorry for the confusion - I'm sure it's not CQManiac !! hehe CQMATIC !!

Will keep you posted!!
Over and out!
-vhelp

Well it could be :!:
Just let me know :cool:

Hi again..

Sorry, I'm back..
Actually, I thought you did some .tpr tweaks (your temp files, that is)
but since you said you DON'T, then I'm stumped, since even my later
version TMPG is falling up.

Member my short 258 frames I mentioned ??
..How it's still repeating those same frames ??
..and, (probably didn't mention) but those same 258 frames repeated
from a previous experience, ..say first 20 minutes of a vob - thats the
confusing part, cause it should have (on the whole 128min encode) used
different frames.

also, I made sure that my [ ] Source Range was unchecked. And, resaved
it. And reloaded it w/ you latest version, but it's still [x] checking the
source range anyways. Cause, when I go back into TMPG, (one used in
your CQMATIC) I open the Advance tab, and [x] Source Range is checked
again. BUT, when I load in my .tpr file, the [ ] Source Range is unchecked!

I will try to find a newer TMPG version and test again. If it works, then it's
just a matter of "nailing" the latest (oldest) version TMPG, so that others
don't fall into the same predicament :wink: IF anything, at least we know
for sure, what the cut-off is ie, TMPG v2.53 :wink:

-vhelp

@ Kwag..

Ok, I found a TMPG v2.56

I'll give that one a try !!
