Recommendation for capture card with more than 1 live output

[nullptr]

Hi everyone.

I'm looking for a recommendation of a capture card that has at least 2 separate video inputs which will also allow me to preview and capture those two inputs live and simultaneously. I'll be writing my own software ( using MS DirectShow, on a Win7 x64 OS ) to create and record picture in picture, so it's very important that both images can be processed and output by the card live and simultaneously.

The video input needs to be standard PAL D1 ( I'm in the UK ), so the higher HD resolutions are not a requirement but obviously would make things easier in the future if needed be.

Thanks and regards,

Dave.

The only full D1 cards I have seen with two capture ports are also TV tuner cards. These cards are the Hauppauge WinTV-HVR-2200 and 2205 (UK models) or the similar N. American cards (WinTV-HVR-2250 and 2255). Each of these cards has 2 analog capture ports and 2 hardware MPEG-2 encoders. (The second analog A/V port is on an auxiliary bracket.) All of these cards can only do hardware MPEG-2 encoding for analog input. I have not seen any full D1 capture cards that provide dual capture ports and have the ability to provide uncompressed video input.

Usually CCTV capture cards are equipped with more than 1 input and some of them are capable to perform full framerate on each input.

Thankyou for your replies.

I don't really need 'full D1' as I guess I could capture the audio using a different method, but I do need the full 720x576 @ 25fps image from both camera sources. Another thought I just had might be using 2 separate capture cards. Do you have any experience with 2 identical capture cards that can be plugged into the same machine without any conflicts, or should I stick to using 1 card with multiple in and outs?

Thanks again.

You may want to poke around the blackmagic design site a bit. Their solutions aren't necessarily cheap, but definitely time-tested.

I see some indications that you don't really know what you are doing at this point and haven't thought this project through sufficiently.

For example, full D1 has nothing to do with audio. Full D1 refers to the video resolution. In PAL land, that is either 704 x 576 or 720 x 576.

What is your budget? There are video capture cards from companies like Matrox, Osprey, and Blackmagic with an SDK for those who need a professional solution, however these are not cheap. Another thing to think about: If you want to get video capture cards that provide uncompressed output and rely on software for compression, then you will need a PC that is able to handle capturing and encoding two SD video streams at the same time.
