At IBC, Blackmagic Design introduced the a new B4 lens mount modification for its Blackmagic URSA Mini PL camera that lets it use broadcast HD lenses.

The Blackmagic URSA Mini B4 Mount is designed to replace the existing PL lens mount on Blackmagic URSA Mini PL, turning it into a B4 camera for HD. To install the B4 mount, customers simply take the PL lens mount off and bolt on the B4 lens mount.

The Blackmagic URSA Mini B4 Mount features precision glass optics specifically designed to match Blackmagic URSA Mini’s sensor with high definition broadcast B4 lenses. The B4 mount also features spherical aberration correction so customers can use their lenses wide open with no blooming effect. The mount can be used with both 4K and 4.6K PL models of URSA Mini.

Blackmagic URSA Mini PL also includes a new lens control connection that works with both PL and B4 lenses. This new connection supports both analog and digital lens control standards and also provides iris control and power for the lens.

When used with high definition B4 lenses, URSA Mini shoots clear HD images that have a high dynamic range and look better than the images from a traditional broadcast HD camera. Plus, broadcasters can use their URSA Mini PL with B4 lenses on one job and then switch back to PL lenses for another job.

“Since we announced URSA Mini at NAB earlier this year, broadcasters have been asking us for a B4 lens mount,” said Grant Petty, CEO, Blackmagic Design. “We listened carefully and designed a way for them to use the B4 lenses they already have for high definition production, and still give them a camera that works for Ultra HD and 4K production because they can switch back to a PL mount lens whenever they need. The most exciting part about this announcement is that broadcasters using URSA Mini get the HD camera they need today with modern file formats like RAW, ProRes and DNx plus they also get wide dynamic range so the quality of the images are much better.”

Vicon Introduces Mobile Mocap at SIGGRAPH

1
Motion capture systems developer Vicon is previewing a futuristic new “Mobile Mocap” technology at SIGGRAPH 2011 in Vancouver. Moving mocap out of the lab and into the field, Vicon's Mobile Mocap system taps several new technologies, many years in the making. At the heart of Mobile Mocap is a very small lipstick-sized camera that enables less obtrusive, more accurate facial animation data. The new cameras capture 720p (1280X720) footage at 60 frames per second. In addition, a powerful processing unit synchronizes, stores, and wirelessly transmits the data, all in a tiny wearable design.
