That's the point! Here in Germany we only have PAL. I'm a DVD-chunky and I'm still now in holidays.
I'm little like Nero from the Matrix-Movies...

Yeah. What is CQMatic...
OK... I changed the sense of this line a little bit...

When You're earler finished with Your beta 3 tell me...

No cosmetic changes at all for BETA 3. Just functional changes. As I said before, it only failed once (longer prediction time) on one movie (k19). Other than that, it's solid as a rock

You said You calculated Your movies manually before You test it with CQMatic. Can You discribe me the way how You did this.
So we both have chosen the same way and I can tell You exactly if it works in PAL like You wanted it that it works so...

yeah!

first of all, super programm, its working fine!
but i think iŽve found a bug

í wanted to use it with Band Of Brothers part 4, which is ca. 57 min long, moviestacker gave me a average bitrate of over 1700. i used this values in cqmatic, but it didnŽt work correctly, it used 1 as cq value...

think it canŽt handle too short movies or to big average bitrates?

Thanks tigger,

I haven't tested on short movies, because I didn't have any on hand. I'm simulating that right now by creating a .d2v of 57 minutes, and testing the result. I'll fix that today

Oh my god that .... IS.... SOOO.... SMART!!!!! I never even bothered to look at the 2nd tab in moviestacker. And I can even raise my 80min CD time to 81min 59sec to accomodate for overburning! This is BRILLIANT Kwag! As us chinese say "YOU SO SMAHT!"

One tiny question. What does the Authoring tab mean in mstacker? I'm confused why the only options are SVCDs

That's to take into consideration extra data size created by the authoring program to be used. I leave mine set to "vcdimager SVCD"

@tigger,

My 57 minute test worked flawlessly

Here's part of my log, typed manually, because I still don't save the log

Execute.
Movie Time: 57
Average Bitrate: 1814
Full Encode Mode.
Sample size: 15295.89KB
Executing Prediction Phase...
Using CQ of 80.0
Encoder started...
Encoder end.
Difference = 1.354983
Using CQ of 90.00
Encoder started...
Encoder end.
Difference = 1.215291
CQ ABOVE watermark. CQ set to 90.0
Using CQ of 90.0
Encoding set to Full encode.
Encoder start...

I'm getting the same results as bigggt. When chosing to make a prediction only. It makes a sample alright first. But keeps encoding the last frame until the total number of frames for the movie. So I get a sample having as many frames as the movie. But only about 1% is frames from the movie the other 99% is the last frame over ,over and over again???????????

hm....bizarre bizarre

did you load your d2v in tmpeg , chose template , saved as text and started cqmatic with that one?
iŽll do another test later with such a short movie...

so iŽm testing with pal movies, iŽm converting one now, iŽll tell you later if it succeeded

bye

Try adding the line KillAudio() at the bottom of your script. That should cure this problem.

No. I created a .avs with the current optimal script, and I use MovieStacker to open the .d2v, and get the movie time and average bitrate. TMPEG will process the .avs. Not the .d2v directly

Let me know

Edit: I'll try the same thing now, but directly opening the .d2v

I find that once you use CQMatic once, it checks on the Source Range option in tmpgenc but doesn't uncheck it upon completion. That means next time you load tmpgenc you'll have to restore cut editing and deselect source range before you save your next project file. To the person having problems with cqmatic try recreating your project file but this time ensure that everything in the source range field is set correctly.

That's because TMPEG remembers the last load. So it will always startup with the last settings. Just load any of your project files before creating a new one. That will clear all to default. I can't control that, because once CQMatic launches TMPEG for the final encode, CQMatic is done, and has no control on the external encoder. CQMatic never modifies your project files. It reads your project files, and creates a new temporary project file to work with. So your project files are all untouched, and you can load any of them to reset the settings

@tigger

Just finished a test reading the 57 minute film by processing the .d2v directly with TMPEG. It also worked flawlessly. Started with CQ of 50 (as set in my project ), then jumped to 90, then detected the high watermark MAX, and started full encode at CQ=90.

hmmm so iŽll try it in the evening

iŽm doing another test now, with a 91 min movie, i must see the whole thing in the end, but it looks now as it doesnŽt use the whole space of an 80 min cdr, it will be perhaps 700-730 mb file, although i checked 80min cdr in moviestacker, but iŽll test this one later

so again, thx a lot for cqmatic, greeeaaat

Of course because you're encoding only the video stream
So the final file size will be video stream + audio stream, and that is equal to ~800MB.
You have to encode the audio separately, unless you have set audio on your project file.

hehe no no

i mean video + audio stream ,already muxxed will be perhaps 700-730 mb, the video stream alone perhaps 610 mb

but iŽll let you know when encoding is finished.
