With products like the DeckLink Studio from Blackmagic Design you can really boost your creativity without having to break the bank. This range of SD / HD video cards and other essential items from Blackmagic, designed for the creative video specialist, aim to provide professional features at an affordable price.
Depending on the video inputs and outputs you require, there is a DeckLink card to suit your requirements. For example, the Decklink Duo works just like having two cards side by side as the two inputs perform capture and playback independently of one another. At the entry level, there is the popular Intensity Pro which has HDMI and analogue inputs for HD capture and playback.
