One of the most exciting announcements to come out of last month’s NAB was undoubtedly Blackmagic Design’s new 4.6K capable URSA Mini.

The newest miniature procam on the block is said to be the world’s lightest handheld Super 35 camera and shares many of the same features as its bigger brother, but in a compact and far more portable form.

Let’s face it, the original URSA, is a beast of a camera. It was designed to do the work of a number of different accessories, removing the need for external sound recorders, or even on-rig monitors.

Weighing in a almost 8 kilos without its sensor attached (the Mini weighs 2.27 kilos), this heavyweight procam is not what you would grab for some quick and dirty motion shots. Not only heavy to hold, it also ‘fills the room’, taking up so much space it has relegated ‘zones’ for crew to work from.

That aside, it’s a popular camera with an outstanding price point, placing it within the budgetary reach for most indie filmmakers.

So, it really comes as no surprise that the URSA Mini announcement generated a lot of buzz within the industry, particularly when fitted with the new 4.6K sensor (also introduced at NAB).



The URSA Mini’s 4.6k sensor is capable of 4608×2592 output with a very decent 15-stops of dynamic range, an 800 ISO base level and built-in refrigerated cooling.

BM’s original 2.5K Cinema Camera (with its 13-stops of dynamic range) excelled in rendering colour (particularly skin) and can be easily cut together with the ARRI ALEXA.

The URSA development team have said that the new sensor features colour tech similar to that found in the Cinema camera but with the additional benefit of greater dynamic range, meaning for a much smaller cost to your film budget you can expect colour performance equal to (or very close) to that of the far pricier high-end procams.

Another nice addition is the ability to switch between rolling and global shutter without ‘stop-loss’ or decreasing light sensitivity. Meaning users can effectively double their frame-rate from 30fps (in global) to 60fps (in rolling) quickly, without the need to stop and reset everything, which is brilliant if you’re shooting any kind of action.

The sensor is also capable of shooting in 120fps continuously, albeit 1080 windowed mode only. Still, it’s great to be able to shoot for as long as you need, rather than in only the short bursts that most cameras in this price-point offer.

Resolution Sizes

  • 4608 x 2592 (Native 4.6K Resolution, RAW)
  • 4096 x 2304 (4K 16:9, RAW)
  • 4608 x 1920 (4K 2.4:1, RAW)
  • 3840 x 2160 (Ultra HD, all ProRes formats)
  • 3072 x 2560 (3K Anamorphic, RAW)
  • 2048 x 1152 (2K 16:9, RAW)
  • 1920 x 1080 HD (All ProRes formats)

It’s worth noting the addition of the 3K anamorphic mode, which we’re sure many will be appreciated by many cinematographers.

A standout addition to the Mini its built-in Gyroscope which allows recording metadata of camera pitch, roll and yaw movements when working in RAW.

This means that in post that metadata can be used to track the camera’s movement precisely when placed in any kind of 3D environment, or for adding VFX and graphics.

Despite the fact there is a lot of great camera tracking software available these days, being able to just feed in metadata is going to speed up that process, particularly if it’s been shot in handheld, or if motion tracking points weren’t placed in the frame.

It’s just a great addition and if implemented as realtime metadata collection (rather than just once during each shot) then this could be immensely beneficial in post. Although, it is missing an accelerometer, so that will limit its use in post to some degree.

Added to that is BM’s free version of Fusion 7, (its VFX and Motion Graphics software), and the fact the URSA Mini comes with BM’s professional colour grading software, DaVinci Resolve, making it an attractive package for micro budget productions.



The camera’s is made from magnesium alloy making it a rugged little camera, weighing in at 2.27 kilos (5 lbs).

It features a full HD, 5-inch fold out LCD touchscreen for monitor and operation menu, nine 1/4-inch threaded points on its body for mounting or adding accessories and its side handle features LANC based record, focus and iris buttons.


It also features multiple connections, like 12G-SDI out, HD-SDI monitoring out, 2 LANC inputs, stereo XLR audio (with 48v phantom power), timecode in and reference input. The 12G-SDI output is capable of 2160p/60fps (when using BNC cable) and can be switched to 6G-SDI or HD-SDI.

With continuous recording to dual CFast 2.0 cards in either CinemaDNG RAW 3:1 @180MB/s, RAW 4:1 @135MB/s (4608 x 2592) or in ProRes 444XQ @250MB/s (3840 x 2160).



The URSA Mini 4.6K can be purchased with either the EF-mount for AU$7035 or the PL-mount for AU$7755.

Also available is the URSA Mini 4K with either the EF-mount for AU$4235, or PL-mount for AU$4925.

BM has said that shipping will begin later this year in July, 2015.
