Cooling fan. The URSA Mini 4.6K is cooled
like a Mac Pro: air is drawn from the
bottom and blown out the top. Electronics
are sealed outside the cooling “tower”
so moisture is isolated. Nevertheless, in
locations like Vancouver, it’s always good to
use a rain cover.

At left on top of camera: Blackmagic Video Assist 4K. It has a 7” touchscreen 1920 x
1200 display. HDMI and 6G-SDI inputs record ProRes or DNx onto SD cards. (Recom-
mended: UHS-II SD cards).
Blackmagic’s Video Assist 4K 7-inch Recorder/Monitor works with almost any SDI
or HDMI camera—not just the URSA Mini 4.6K. It records 1080 HD up to 2160 30p
(3840 x 2160) UHD, in 10-bit 4:2:2 ProRes, DNxHD and DNxHR files (Quicktime and
MXF formats).
In trigger-record mode (shown here, connected to the URSA Mini 4.6K’s SDI output), the
Video Assist 4K will automatically create a simultaneous copy of the camera’s internal
recording—which is helpful as a backup or edit-ready proxy.
