After experimenting with Fraps, PlayClaw, and the Hauppauge HD-PVR, I've bought a Blackmagic Intensity Pro video capture card and after a lot of fiddling with settings this morning, I finally have it working. I haven't done any real shooting yet, just testing, so what follows are just first impressions, in case they help someone else.
I'm using a two computer setup, with SL running on one computer in full graphics mode and the Intensity Pro in the second computer. Both computers are Windows 7 64-bit, dual core Intel 3.0 CPUs; the SL computer has an NVIDIA GT260 and the capture computer has an NVIDIA 9800 GTX.
The Intensity Pro comes with a DVI-HDMI adapter cable that I'm using to connect the two computers. The DVI end is in my SL computer's video card (NVIDIA GT260) and the HDMI in the Intensity Pro. The SL computer is set for dual monitor output, with duplicate displays. I'm using the NVIDIA control panel to set resolutions.
EDIT: The DVI-HDMI adapter cable doesn't come with the Intensity Pro. When I wrote that, I forgot that I ordered the adapter separately from Amazon.
With this setup, I can capture at the following resolutions (I didn't test lower resolutions):
- 1080p 30
- 1080i 60
- 720p 60
Blackmagic recommends against using the Intensity Pro with a single standard hard drive and instead recommends using a RAID with two disks for SD or with at least 8 disks (!) for HD. I'm using a single fairly fast SSD (OCZ Vertex 2) which looks to me like it will be barely
The Intensity Pro comes with speed test software for testing your capture hard drive; I've attached an image (it's after the end of this post) showing the results for my Vertex 2, showing the fps for various resolution and recording formats. Blackmagic recommends leaving a very large margin below this. For example, if the speed test shows that I can record at 56fps, I probably should aim for shooting at a substantially lower fps. Blackmagic recommends allowing a 100% margin with a two disk array and a 30% margin with an 8 disk array.
The Intensity Pro comes with Media Express for video capture and playback; I've been able to capture with it and also with Premiere Pro CS5.
I'll post more after I've actually used it for a while. In the meantime, I hope this helps someone.
