Glitchy system – new Decklink user :( HELP!!!
Ok I have a WinXP SP2 box (see specs below) Running Nuendo 3 and I just installed a decklink-SP card. I needed to view QuickTime clips out to NTSC (plasma monitor)for clients while working on 5.1 mixes. The integration is great Nuendo uses QuickTime and sets me up with BMD-RGB out and the picture shows up good (but jerky) but the Audio is all cracly. Seems like and I/O conflict but I have moved the cards around and the decklink is on it’s own IRQ now and it still does it. If I leave the Decklink in the computer but disable it then all the audio is fine.
Oh and one more thing…i have a DVRexRT Card (2 PCI slots) in this system as well and there doesn’t seem to be any conflict. Although being a system integrator I would normally never tell my clients to put so much specialized hardware in one box. BUT…I need it all in this box for myself 🙂
I hope this all helps. Thank you in advance for any thoughts. (I think tonight I will try pulling out the rex and moving the Decklink in those spots)
OK here is my system specs:
ASUS P4C800, P4 3Ghz, 2 Gigs of Ram

very simple error
first get quicktime player pro and extract the audio file from the quicktime video into an wave file.
second import video without!!! audio into n3.
third import the audio file.this is the way we do it.

I will try all that but I think the quicktime I tried had no audio…maybe I am wrong.
Also, to be really clear. even if Nuendo has no video loaded and the Decklink card is just acting as a third monitor, I still get jerky playback out my RME audio card and infact the decklink screen flickers . But if I disable the Decklink in the system properties and leave the decklink phisicaly installed in the system, all of the sudden everything works fine.
Help?

Hi Jason,
Firstly, please ensure you are using QuickTime 6.5 and not the public preview of QuickTime 7 as there are some significant audio changes in QuickTime 7 Public Preview and we will need to modify the DeckLink drivers to support this change when QuickTime 7 is released.
Next, open the QuickTime

Arg… This thing is still giving me fits…
OK more details,
I am running Quicktime 6.5.2 and I have noticed that as the timeline plays in Nuendo it is really sputtery and even seems to slow down (choppy) but after it has played a fair amount of the material if I rewind and play again what has played it is sort of clean. It seems as though it is similar to when I am working in After Effects and it is rendering to ram or something. BUT I need it to just simply play clean the first time (EVERY TIME!!) there is no rendering involved here. I have converted my quicktime files into BMD 8Bit files with no Audio using Procoder. and I still get bad playback. HELP??
Also what is the difference between 8Bit and 8Bit (2Vuy)

Hey Guys…
GOOD NEWS! I got this system running. Turns out it was the Firewire Audio interface that was giving me so much grief.
Thank you all for your help.

Hi Jason,
This is great news and thank you for letting us know. Can you tell us how you discovered that the Firewire Audio interface was the cause of the problems and also how you fixed it? This would be very useful to know in case someone else runs in to the same problem.

Hi Paul,
I’m glad to hear you have overcome the problem.
[jasonsilzle] “what is the difference between 8Bit and 8Bit (2Vuy)”
There is no difference between these two formats other than the header information. Blackmagic 8bit is the current format and is directly compatible with Apple’s 8bit format. Blackmagic 8bit (2Vuy) is the older Blackmagic format which is what we introduced before Apple released there own codec. The Blackmagic 8bit (2Vuy) codec is included for legacy reasons including support of older Blackmagic 8bit files and is also what is used by Pinnacle.
