Hi Totonho03,

You should be able to throw any (time) size movie at CQMatic, and it will either encode at a max of 90, or at a min of 1 ( if you like very low quality videos :lol: )
The program should protect MIN,MAX bundaries now :)

I'm giving it a try right now. I forgot to count how many attempts it took but it no longer got stuck at 40.49 and instead zeroed in on 37.53. This was on T2 special edition, trying to fit 153 min on one 82 min cdr (with overburn) as KVCDx3. I'm going to try some at lower resolutions and see what my CQs are like, then encode some samples and see how they look.

The only gripe I have with cqmatic is the longer sample times than ToK. I guess I'm just used to Tenra's fast predictions, but I could normally zero in on a CQ in 20 min tops. But now it takes me up to 11 min a sample, and if it takes 4-5 samples well that just adds up! (guess I shouldn't look a gift horse in the mouth but.... :wink: )

;)
Well, If we can get 98% accuracy every time, then I wouldn't mind waiting a ~15% extra overhead for prediction :!:
I'd rather wait that extra time, than find out the next morning that it's under 40MB or over 20MB :!:
But then again, only if it's a consistent ~2% precision every time :!:

Kwag:

Sorry for this, but I am getting a loop with vRC 1.
It started at CQ 60, then it went to:
68.19>72.28>73.40>72.31>72.37>72.32>73.34>72.35>73 .31>72.37>73.29>72.38> 72.37> 72.40 and is still going. I have checked and rechecked my numbers, and the only thing that I did wrong was to use 2500 as max number, instead of 2000. Would this create the loop?
Each time it encoding takes about 13 minutes, and the prediction is now over 2.5 hours.........

Totonho

P.s.- Would you loke for me to send you the log? Is a long one......

Hi Totonho ,

I'm now too tired to think :!:
I quit for today. Tomorrow I'll tackle this.
This doesn't make any sense 8O
And the test/predict cycle is really boring :!:, so I have to wait a long time too before I get results.
And the worse thing is that I don't get a single movie to fail on me, and that makes things worse, because I can't reproduce the problems :roll:
To be continued tomorrow .....

Later,
-kwag

Something very odd happened:
I stopped the TMPEGenc, it was still in a loop, printed the log, and surprise, the printed log is longer than the log that the CQmtic was showing win their screen.........No, I only had 4 glasses of Merlot, and am not hic, drunk......... The log even states that CQmatic completed its cycle at CQ 73.054291, (the difference between that one and the previous one is 0.217361, which is less than the .25 tha kwag was talking about............

I will start all over again, but am not sure if I am going to wait a couple of hours for it to finish, so I will report manana por la manana.......

Totonho03

With RC1, my problem seems to be gone :!:
Here's my log (same source as always):
I've tried with a first CQ of 60, i'll let it do a full encode and then i'll try with different CQ's at start.
Thx Kwag for working so hard on this :!:
And thx for the logging feature (very important for me :D ) :drink:

Well, my doubts where right. With another CQ at start, final CQ is different. I've done the second prediction exactly with the same settings except first CQ. This time i started with 90. Here's the log:
EDIT: Same behavior with avs-script with filters. Logs above were done without filters.

sorry kwag, but i still have the problem with short movies, its getting me crazy :)

well still have the problem with short movies

Good morning /afternoon gentlemen:

As mentioned, I left the tool running last night, with the max number set at 2,000, and the results were positive:
It went through its calculating routine 6 times, and received a final CQ of 78.3089600 and a CQ difference of .218658.4, the CQ values were:
I printed the previous log as well, and it shows the point where I stopped the encoding. However, the log keeps on going, perhaps looking at the looped numbers...I do not know, I must have also asked to dump the log twice, that explains the 2 sets showing completed CQmatic)

Kwag, something that perhaps would have answered this without doubts is a clock. Do you think that a clock could be placed at the encoding starting and ending points? Just a question. (I just asked CQmatic to dump the info from my recent test to the clipboard, and I now have 2 sets of the same log, it appears that the command is not clearing the contents of the clipboard, if CQmatic has not been closed.)

Total prediction time appears to be around 1 hor and 30 minutes, this for an 80 minutes film and an average bit rate of 1149
Thanks Totonho

Hi Totonho,

can you try the same prediction with a low starting-CQ :?:
I would like to know if it is predicting the same or a similar value.

Hi Krassi.

Will do that, I will start in about 15 minutes, the result will be there in about 1.5 hours.

Totonho03

hi krassie...
well started preditcion of 57min with low cq, 30
jumped directly in the 2nd pass to 90

Kwag: I notice that CQMatic takes a much longer time to encode the same number of frames in its prediction samples than with tmpgenc on its own. For example, the movie I'm on now takes 12 min to encode 3240 frames. But if I add the line trim(0,3240) to my avs and just load that directly into tmpgenc, it only takes 2 min! Sometimes it takes 5-6 tries to get the right CQ, which would mean 60-72 min, whereas I'd "expect" it to only take 10-12 min. Can you shed some light on what this may be due to?

Hello Krassi:

I re-run CQmatic, starting at 70, and this is what I have:

The previous, at CQ 60 was
Hope this helps

Totonho03

And this is my latest log:

Do not think that I need to quote the previous log, but I will do so if you think it is needed.

Thanks

Totonho03

hmmm wondering :)

set moviestacker to 90mincdr, wanted to have 120min movie on 90min cdr, videostream SHOULD be ca. 780mb, but its 820 mb ??

thought that the filesize woulder NEVER go above the maxiumum?

perhaps, next time, i try to configure moviestacker 88mincdr ;)

anyone tested running cqmatic for 90min cdr configuration?

Please get RC-2 :!: ;)

-kwag

Hello kwag:

I just finished running a test with RC-2. Here is my log ( I have changed its format a bit to save space):

I also did a test using CQ 70 on the previous software, RC 1, and the final CQ was:

Which as you can notice it is exactly the same thing.

Hope this help some.

Totonho03

Thanks totonho03 :)
But use RC-2, because it fixes many problems with short (High CQ) encodes that can fail miserably with ;)
