Blackmagic Ursa Mini 4.6k EF Test Footage

Recommended Posts

I have a question actually in regards to this camera. I shot this video with 5 filters on:

It was in an effort to take away some of the "sharpness" of the camera. But in doing so I've gotten a lot of artefacts in my image. I'm wondering if this is a camera issue or it is because of all the filters I stacked on (I'm 95% guessing its because of the filters).


I mixed a Tiffen Black Satin 1 with a Tiffen Black Pro Mist 1/4. There was also a Hoya UV, IR and a SLR magic Vari ND.

Haha I'll take that as a compliment if David can't see any issues in the footage :P

I think some people were spotting some FPN in the blacks etc. Maybe it was just on my monitor.




Overall, I do like the look I've been able to achieve on this camera through this setup. I'd love to know more of your thoughts David on stacking filters etc.

I'd avoid stacking that many filters -- I'd probably not bother stacking two types of "mist" diffusion, the Black Satin is already a combination of a GlimmerGlass and Diffusion-FX... I'd probably just use a heavier GlimmerGlass or Black ProMist by itself rather than combine a Black Satin and a 1/4 Black ProMist. And with all of that glass, I'm not sure why you need a UV filter as well, generally digital cameras aren't as sensitive to UV as film cameras. And I'd use an ND-IR combo filter.


With the blocky compression artifacts of YouTube, it's hard to see fixed pattern noise in the blacks.

Is there still FPN with the new update?


Looking to get a camera in the near future and this one keeps popping up, well the mini 4.6K

There are a few problems like the power button being behind the display as well as the Cfast slots but they can be worked around...


The main thing is that FPN as I do a lot of night time shooting in woods and stuff so that is what is stopping me from clicking buy on this camera atm.
