vhelp 07-30-2003 02:14 AM

Hi (last time) Kwag..

This time, I got the same issues before, w/ the error mesage about 3:2 pulldown.

Also, a new twist..
The window open very fast, three time and closed down. I know I've read
this issue before, so I'll give a search tomorrow, cause I'm really tired now :)

Thanks for lots,
signing off...

But, here is my log file FWIW:

Now I cant fit it to cd, even with 112 kbps sound
CQmatic - version RC-3
Now i try to predict with newest (RC-5) version of CQmatic...

Still no success!
With RC5 the size of result is 771 802 741

May be MovieStacker gived me WRONG average bitrate? With which tool i can check it?

And I'll try version 1.0 final...

@Kwag

Why use a max bitrate of 2000? SVCD or x(S)VCD can go higher, why not use it? Would it not improve the encode?

Also, do you have answers to my previous post?

So, if I want to encode a sample with my script settings and fave template to check the resulting quality, how do I do it?

Also, do the filters loaded in the optimal script come with Avisynth or are they external?

What sort of figures are passed to the Letterbox and GripCrop filters?

Cheers

This probably sound stupid but how do I find the log for cqmatic, I know it says it copies to the clipboard, but where is the clipboard, because I cant seem to find it on my comp?

Clipboard =

copy -> clipboard
paste <- cliboard

(ctrl+c and ctrl+v)

Fixed in 1.01 ;)

Thanks Razor..I should've realized it was something simple.

It has to do with the linearity range in TMPEG, when allocation bits. If the MIN and MAX are spread to wide apart from average, specifically when average is not centered between MIN and MAX, prediction will not be as accurate.

This is a CQMatic thread :!: Not an AviSynth thread :!:

Kwag, just have to ask...........
 
:?: Given the rapid development of CQMatic and numerous postings and tests, have you any speculation about when you will reach release 2.0 that includes the DVD friendly bitrate calculator?

I'm still testing with KDVD by using the prediction formula you so thoughtfully posted and really appreciate the effort you're putting into this. I think the day is quickly approaching when we can just start CQMatic and sit back and watch it do all the work! :D

It's been a long time since I saw your first postings on another site that described putting an entire film on a single CD. :D KVCD/KDVD and now automatic prediction!

kwag 07-30-2003 02:59 PM

Hi nicksteel,

I don't have a time frame yet, because I want to get prediction as perfect as possible. There are still some inconsistencies with interlaced sources and DivX sources. Not as bad as before, but still not as accurate as I want it to be. So you'll be seeing 1.0x releases, which will be either bug fixes, or prediction adjustments only. After that, then I'll release version2, which will sport the calculator and who knows what else :)
But I assure you that when we are happy with prediction, count on less that 24 hours, and you'll see version 2 posted ;)

ok, heres my results on Dog Soldiers PAL DVD (99min):

movie stacker average bitrate - 1009
i used 2000max and 300min in tmpgenc
movie stacker wanted file size - 727mg
encoded file size - 750mg :(

the encoded file size was not too far off, but i still can't fit it onto a cd :!:

could it be that movie stacker is giving me a high average bitrate for some reason :?:

kwag 07-30-2003 08:26 PM

Hi kinggee,

Did you use CQM 1.0 or greater :?:

Edit: I get an average of 987Kbps with MovieStacker for a time of 99 minutes :!:

-kwag

kinggee 07-30-2003 08:30 PM

hey kwag,

i used CQMatic Version 1.0 RC-5

i am trying Version 1.02Release now :wink:

kwag 07-30-2003 08:44 PM

Based on my average, yours would give +17424KB over required :!:
Check that you have set Moviestacker to "MPEG Multiplexing: bbMpeg VCD MPEG-1", and "Seq. header alignment" checked
Then, you should see 987Kbps for average bitrate.
So your final size would have been 750MB (~768,000KB - 17,424KB) = 750,576KB. And then 750,576KB / 1.024 = ~732.984MB which would have been damn close to your required 727MB :D

i've stuffed something up good :!:

kinggee 07-30-2003 08:55 PM

ok i checked the Seq. header alignment box and now it gives me an average of 995. Better, but not 987 :roll:

i am using 96kbps sound

bigggt 07-30-2003 09:02 PM

Hey guys, man got home from work today and found three new releases
:D and see that the warning about divx and xvid is gone.

one question Kwag you wrote
Quote:

and "Seq. header alignment" checked
in moviestacker is this just for a certian project or should it be checked all the time because i looked in my settings and mine isin't checked.

Thanx

:lol:

i re-installed tmpgenc and everything seems back to normal now :)

but i still can't get movie stacker to give me an average of 987 :!:

SORRY :!: Don't check Align sequence headers. It must be unchecked :oops:

:doh:
