Video Assist Brightness as Nits or cd/m² ?

PostFri Jul 28, 2017 3:11 pm

Anyone knows exactly what is the brightness of a Blackmagic Video Assist monitor, measured in Nits or cd/m² ?

Since I am mostly shooting exteriors, seeing the monitor is a major issue for my productions. Sun hoods help to some degree, but gemerally the BM Video Assist seems a bit dark to me.

I have looked all over Google looking for that information. It seems ridiculous for that to not be disclosed. Any other manufacturer has that info for their monitors.

In one forum, I happened to find, that the BM Video Assist has 350 cd/m². Well that seems a bit low.

The new "Aputure VS-5X" is now listed as 450 cd/m² and has all of the same functions at a lower price.

I don't know what the NITS rating is.

I do know that I've used it successfully in bright (and I mean Australian bright) outdoor conditions and it does pretty well.

If you think it's dark, then I don't think an extra 100 nits (if that's what it is) will do much.

You should be looking at monitors around the 1000 nit range to really see a differnce outdoors.

Yes I see your point, a 1000 nits monitor will be the best bet.

Anyway, I will be glad if someone from BM shares the secret number ;)

Emilian, have a look here:
viewtopic.php?f=2&t=60184&p=344405#p344405

I posted a picture of my UM46k LCD at 100% in sunlight and the Shogun Inferno with 1500 nits at full brightness. I guess the VA has similar brightness to the UM46k LCD.

Robert, thanks for the comparison!

Will compare the BMVA 7" with the UM46 monitor tomorrow :)

I work in a rental house and own a BMVA 4K. Our SmallHD 702 high bright is out until next week but I can do a comparison if anyone needs.

Here are some results on "BMVA4K vs UM46:

1:
First, I made sure both monitors have the same angle towards the sun and towards the photo camera.

Full res photo here:

2:
Here I made a quick comparison at 100% brightness on both. Contrast on BMVA at 50%.
Scene exposure was right, just slightly over-exposed. Mostly bright, with some darker areas, white wall, sky and clouds. So, both monitors have almost identical brightness, but I think the UM46 was slightly easier to see.

3:
Then I made a "zoomed in" comparison, in an area, that was slightly over-exposed. It revealed, that the BMVA 4K has less dynamic range, than the UM46 monitor. As you can see, the edge detail on the white wall is lost on the BMVA, while still visible on the UM46. Also you can see that difference in the sky / clouds area.

P.S.
and the BMVA seems a bit greener.

Thats a shame really for BM not to provide such important information about external monitor.
But I am not surprised with BM politics.

You can measure it yourself with any display calibration device.

Thanks for your efforts here, Emilian. It's so rare to see real untouched photos of any monitor manufacturers' monitors.
