Blackmagic Design has announced the worldwide release of Intensity -- a card aimed at professional video editors who need to edit video using High Definition Multimedia Interface (HDMI). The PCI Express-based Intensity card is Mac OS X and Windows-compatible and costs $249 (around £127).

The Intensity features HDMI in for capture from HDMI video cameras and HDMI HDV decks. It switches between 1080HD and 720HD, NTSC and PAL video standards. It can manage uncompressed video capture and playback, and supports Apple's Final Cut Pro, Adobe After Effects, Photoshop and any other QuickTime-based software application.

Blackmagic's On-Air 2.0 software can be used with the card as well; the software enables Intensity users to attach two HDMI-based video cameras together to two Intensity cards in a single Mac, for live mixing. On-Air 2.0 supports auto-sync of video inputs and "genlock-less" operation.
