How to use Decklink card for video spooler?
Hello,
I am interested in creating a PC/video spooler with a Decklink HD card. I’ve seen others make similar devices with AJA cards. I’m hoping it can be done with a Decklink card except for I dont know how to drive the card software wise.
Forgive me if this isn’t making much sense but its Monday and my brain still haven’t woken up. What I’m looking to make is a PC with an HD Decklink card to use its SDI/HDSDI interface. Inside will be a few SATA drives in a raid config or SCSI to store the uncompressed video data. I will not need NLE software such as Premiere since I’m not doing any editing of the video data. I simply want an interface to capture clips and play them back.
However I dont know what software or low level driver interface will let me do that. I suspect that using Mircosoft DirectShow could be a solution but I’m not really a programmer so I’m not familiar with that. Any tips on how I could do this?
Regards,
Jason

Hi Jason,
All DeckLink cards include the Blackmagic Deck Control utility. It is a very basic utility which simply captures and plays back SD or HD movies in the QuickTime file format. You can capture and playback movies in an 8 or 10-bit format and we include easy setups to configure the format of video that you want to capture, eg HDTV 1080i50 10-bit.
While our Windows drivers do support AVI files through applications such as Premiere Pro and Vegas, as well as for developers via DirectShow, the Deck Control utility only captures to the QuickTime format at this time.
The DeckLink SDK on the software downloads page of our web site contains a number of DirectShow examples to help you build your own custom interface to DeckLink cards if you want to do your own thing. The DirectShow filters are already included with our drivers so you have everything you need to get going without having to buy anything extra.
Blackmagic Deck Control and DirectShow filters are included with the card at no additional cost and hopefully one of these two solutions will help you.

Luke,
Any tips on motherboard/CPU combos that are certified to work with the Decklink HD card? Or turnkey places to look at. I would like to put together the smallest PC to use for capture and playback of uncompressed HD. I don’t need to render or tweak the video at all. I’m hoping that a system drive and 2 other SATA drives in a raid config will provide the data rate needed for uncompressed HD.
Thanks,
Jason
