The new Decklink HD Extreme card from Black Magic supports just about every connection you could need. It has SDI (HD and SD), component, composite and HDMI in and out. It can capture at up to 2K resolution, can capture in uncompressed or MJPEG and 4:2:2 and 4:4:4 colour space. It also has plug-ins for Adobe Premiere and Final Cut Pro as well as adding video-out for a whole host of other programs. The price? £499.00 +VAT.

The card is a 4x PCIe card so you need to make sure that your motherboard has a spare slot that can support this.
