Hi Res DVI Capture and Streaming

Hello,

I need to capture 1600x1200 video using a DVI capture card from a company like Foresight Imaging.

Can anyone suggest the most efficient CODEC that will capture an stream at about 15+ fps? Hardware and software costs are not an issue.

Are there any appliances that will do Hi Res capture/streaming? I looked at RGB Spectrum DGY and IPVideo Sys V2D, anything else out there?

Any help will be greatly appreciated.

Thanks,
Richard

We're working on high-def streaming atm but in the early stages. Lucky you that money isnt a consideration - tons of options out there with streaming appliances - I've no experience with them because the cost of a single unit is about what we are looking at for a complete 4 camera system ;)

Anyways, I'd probably handle this (in my cheap and cheerful way) by capturing popping a HDMI converter on my DV output and capturing using something like a Blackmagic (note - only works on Max/Win) card. Streaming is a little more difficult - Many on nerdlogger (http://www.nerdlogger.com/2007/11/how-t ... dv-to.html) has some tips on streaming HDV but so far I'm finding that even with a Core I7 based machine encoding with x264/mp4v is resulting in a lot of motion artifacts even at high bitrates - so much so that I am considering dropping back to 720p for streaming. I need to do a scientific comparison next at various bitrates, resolutions, codecs etc but I'm having some problems with VLC which is holding me up.
