Hi Lars,

I’m not sure whether someone here has noticed such a problem so I have asked for your bug report to be tested on our system and will get back to you when I know more in the next day or two.

Hi Lars,

Which formats have you tried, eg PAL, NTSC, HDTV1080? Were you using an 8 or 10 bit easy setup or something else?

Hi Lars,

We’ve just run a 30 minute pip test and found no shift in capture and playback using Blackmagic Deck Control. Testing was conducted with the DeckLink Windows 5.1 drivers. If you have not already updated, we suggest you do so. If you have ongoing problems, please answer the questions in my previous post.

Regards,

Thanx Luke,

This bug only seems to occur with a DeckLink Pro. A regulard DeckLink card worked seamless (a long time ago) I’ve checked with CD-R backup’s. I experience the bug in both 8 and 10 bit Pal. The bug is persistend troughout driverversions since I received the card in 2004. And I usualy run the latest drivers, as I do now.

Here’s the config, just in case… And I think you guys have something simmilar at your lab

[Luke Maslen] “Which formats have you tried, eg PAL, NTSC, HDTV1080?”
Just PAL, with a DigitalBetacam DVW-500p

[Luke Maslen] “Were you using an 8 or 10 bit easy setup or something else?”
Just the 8 and 10 Bit Easy’s from the pulldown. Only tinkering involved is the get and put off-set for correct timing with the DigiBeta.

Hope this will help. Thanx to the Engeneers to!
Cheers, Lars

Lars and Luke,

I posted a similar message on the Final Cut Forum that had to do a one frame issue when dealing with imported, not captured, audio and video files. In my case, I imported a seperate audio and video files that were known to be precisely the same length, to the frame. However, when brought to the FCP timeline, audio was one frame longer than video. So, I think FCP may have an issue. On the otherhand, I have an Extreme card myself, and I use the BM codecs for most things, so its possible that even in this case the setup for the sequence might have been affected in some way by the BM software.

Hi Luke,

Any ‘luck’ reproducing ‘my’ bug yet?
