Continuing Problem with AVC MPEG4 Shrink to BD25

[philb1964]

Hi, an update to past posts and an observation I am not sure is relevant, but I have noticed that the latest batch of discs I have problems with shrinking to BD25 has been with material that has been shown as AVC MPEG4.

Ripping a Full Disc BD50 to my Hard drive the material plays fine (checked on VLC)

Taking the Main Movie from the above to BD25 (if no shrinking is required) plays fine to VLC & disc

However, if the material needs shrinking, it is extremely jumpy in both VLC on HD & BD-R 25 disc.

Discs that I have had the problem on so far:

Harry Brown (main movie 26 gig to 23 gig)
Bunny and the Bull (main movie to 23 gig)
Permissive (shrinking Full disc BD50 disc to Full disc BD25 resulted in terrible jitter, however main movie which was less than 20 gig copied fine with no shrinking needed)

All versions tried from 7040 to 7065

Any suggestions?

Geez Phil, what is wrong with your machine??? Are you using GPU acceleration??? More info please!!!!!!

[philb1964]

Thanks for the reply - what information do you need? I am a computer novice & run DVDFab with the defaults - and update each version of 7 without deleting the previous version.

My system is Vista Home Premium 64 bit Service Pack 2
Processor Intel Core2 Quad CPU Q8400 @ 2.66GHz
Memory 8 GB

What Video Card?

Phil,
also, go to DVDFab settings, open "A/V Codec" and tell what you see there - all settings.

Thanks for the questions guys. I've copied the details from my system:

Videocard is NVidea GeForce 8500 GT with DirectX version 11.0
Driver Version 196.21
CUDA Cores: 16
Memory interface: 128 bit
Total available graphics: 3839MB
Dedicated Video Memory: 256 MB
System Video Memory: 0 MB
Shared system Memory: 3583 MB
Video BIOS version: 60.86.18.00.00
IRQ: 16
Bus: PCI Express x 16

DVD Fab Settings:
A/V Codec

Video Decoder:
h.264 -CUDA
VC1 = Software
MPEG2 = Software

Video Encoder
H.264 = Software+CUDA

Codec Information
Graphics Chipset :
NVIDIA GeForce 8500 GT

Supported Video Codecs :
CUDA_MODE_H264

DXVA_MODE_H264

CoreAVC : cannot be detected.

Does the last line indicate the problem?

Cheers

No, last one indicates that you have no CoreAVC installed on your machine. CoreAVC is a fastest codec out there and many of us having it. You have to buy is, and it's optional - not a requirement.

Latest driver for your card is 197.45 Please download it from here and install.

http://www.nvidia.com/object/win7_winvista_64bit_197.45_whql.html

Now, back to your problem.
First, I would suggest to make some adjustments in your card. For that, go to nVIDIA control panel (right-click anywhere on your desktop to access) and (a) disable PhysX (b) set your card as a single-GPU.
Secong, go to A/V settings and set VC-1 for CUDA as well. (Restart DVDFab after these changes)
Third, Find any source VC-1 coded, preferably same source that you already processed in a past and had good result. You can use BD Info to identify codec - a little free program, google it.
Fourth. Compress VC-1 content same way as you already did it had good results (you don't have to do entire movie - just a couple of chapters). Check the quality of video, is it good or is it jumpy.

Please let me know results and we'll go from there.

IPopov50,

I've noticed in a few of your posts you recommend disableing PhysX on Nvidia cards, I'm using the 9800gt card with PhysX enabled, do you recommend this feature be disabled on all cards or just in certain cases?

Thanks Papajo

[IPopov50]

@Papajo
PhysX is a strictly gaming and/or graphic feature. in simple terms it creates a realistic environment in a game. Let's say bouncing off the wall object and/or other laws of physics. In newer, duo-GPU cards, PhysX takes up one of the GPUs. Anyway, process we are conducting here for video conversion is calculation extensive and somewhat fragile. You don't want any interruptions and/or losses in GPU capacity. PhysX however, eats up a lot of time on switches... You've got the picture. Yes, I recommend to turn it off on all PhysX enabled cards. You have to turn it back on for gaming though. Otherwise ball wouldn't bounce and bullets wouldn't ricochet

[Papajo]

Great advice, Thank you

Further shrink problems - this time with Fritz Lang's 'M'

Well, I did what you suggested and tried re-shrinking Harry Brown from the BD50 rip (I've no longer got the master disc) and once again the BD-25 HD rip had the jitters :-(

So I thought it could be something to do with the original BD50 rip.. I don't know

However, I have a new problem with the new system..

Got 'M' (Fritz Lang) on Blu-Ray - disc is 43 gig.
Ripped a BD50 to hard drive - fine!
Compressed Main movie (28 gig to 23 gig) - fine!

However, when I tried to compress the whole disc to BD-25 I get an error after the programme has gone through analysing & started - getting to 0.09% Source (00002.m2ts) - a Microsoft Window pops up saying:

"FabCore has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available"

When checked that window closes, DVD Fab is still open, the elapsed time continues to go up, but percent stays at 0.09% & Task Time Left stays at 00.00.00

phil, please tell me you are not ripping rentals, please!!! You know why...

Possible, but we would never find it out.

What version of a DVDFab were you using. Please try 7.0.7.0 and let me know if problem persists.

[philb1964]

I did use M with 7.0.7.0

No rentals, why is there a reason?

yest, there is a reason, read this:

it's illegal

Of course I know that, I only make personal backups - I thought you meant there was different code. I bought this film and after watching it decided I didn't want to see it again so gave it as a birthday present (I know I'm cheap!). The BD-50 has been left on my drive because it's become a mission to get it to work - I re-try with every Fab update (and there has been an AWFUL of them lot recently) but every time after a new 6 hour encode I remain disappointed. And now with the 'M' BD-25 crashing my computer it's almost enough to drive me back to DVD's!
