Blackmagic Desktop Video 11.5.1 Improves Genlock For Capture and Playback Devices

Blackmagic releases firmware for its DeckLink capture cards and a Desktop Video manual. 

Desktop Video 11.5.1 is the latest firmware for Blackmagic Design's DeckLink capture and playback cards.

Video capture cards convert video signals into digital data compatible with a computer and record it. They're ideal for creators and filmmakers who want to capture a video source from cameras, decks, or live feeds directly into an editor or effects program. 

Blackmagic offers multiple DeckLink cards that support a range of resolutions and inputs including 12-SDI, 6G-SDI, and HDMI. The cards support 12-bit RGB, 4:4:4 image quality, and frame rates up to 60fps. They can also capture resolutions of SD, HD, 4K, and 8K as well as stereoscopic 3D. The DeckLink 8K Pro is one of a series of flagships and offers Quad link 12G-SDI capture and playback up to 8K DCI. 

For creators and filmmakers with HDMI supported cameras, the DeckLink Quad HDMI Recorder provides PCIe capture with up to 4 HDMI inputs. It's ideal for a multi-camera video podcast or live stream.
