Decklink 5.0b Drivers DVCProHD Stops Working
I’m running Final Cut Pro on a G5 Dual 2.0 2.5 gigs of RAM with a Decklink HD and a Panasonic HD130 deck hooked up. I’ve been running fine like this for about a week now, until today. For some unknown reason, I can no longer capture to DVCProHD in Final Cut (I’ve been using Blackmagic HDTV 1080i 59.94 – DVCProHD) and all was working fine. Toda, I went to put another tape in a long series of tpaes in –nothing has changed in the interim — and now it starts to digitize, waits about 3 seconds, and says there were dropped frames. I can capture 8-bit and 10-bit fine, so I know it’s not the drives, but I can’t capture DVCProHD. It pretty much craps out right away, and it wasn’t doing this just 24 hours ago. Did I accidentally hit something?
Anyone else have this problem?

Hi Christopher,
If none of your settings changed on the computer, then maybe something changed on the deck when you were changing tapes? This doesn’t entirely make sense as I would expect any such change to also affect 8 and 10 bit captures but it would be worth checking the settings on your deck.
Can you also test saving to a Blackmagic HDTV 1080i 59.94 – JPEG timeline and see if that compressed format also suffers from dropped frames? The DVCPRO HD codec is less demanding on your disk storage but places greater demands on your Mac’s system due to the compression or decompression cycles involved with any compressed codec. However if it worked in the past, it should work fine now. The JPEG test will provide a useful comparison. If it also fails, please try a JPEG capture by quitting from FCP and use Blackmagic Deck Control for your capture. This will provide a useful comparison test.
If you have any interactive antivirus software, make sure you disable it’s automatic checking of downloaded files as this will cause dropped frames.

Unfortunately, because of time constraints, I had to take the decklink card and put it into a Final Cut 4.5 G5 and run the 4.8 drivers for now. Before that, I did capture jpeg footage fine, so I think it’s just with the DVCProHD codec that I was having the problems.
The thing I noticed was how “reliable” the timeout on the DVCProHD capture was. From the moment I hit Capture Now, I had 5 seconds before it dropped a frame. I’d count to 5 and then it’d report the dropped frames on capture. If I cancelled out of the digitize before that, I’d have 1-4 seconds of usable DVCProHD.
