Samsung NX1 Green Screen Quality

[twentytwenty]

I am looking to purchase the Samsung NX1 as a possible camera to use for my company videos and corporate training. Has anyone tested the internal quality when keying green screen with the NX1, I have seen tons of test footage on the web for the camera itself, but have not seen any green screen tests. I wanted to see if anyone here has tested it out or has some test footage I could use/see.

Thanks!

I'll likely buy one when a big green screen project gets green lit from a client. Everything about that camera is adding up for me. EOSHD.com has much more activity on the NX1 than DVXuser, you might check there.

LenRentals has the NX1, so renting for a weekend might be a good idea for testing, I may do that as well - I'm only interested in the body, I'd put my Nikkors on it.

That said, everything I've seen suggests this could deliver the best possible keying experience below a 4k Red file. Resolution has trumped Raw in every test I've found (IE, the GH4 at 4K beats the BMC Raw cameras at 1080 and 2.5k). And many people really prefer the sharpness and IQ over the GH4 - plus you get the bigger sensor. I have yet to see any tests of the NX1 with the Atomos 4K recorder, but that could be a remarkable 4k ProRes solution for $3500… or, like many DSLR+Atomos combos, it might be a tough call as to value (though skipping H265 issues alone could be great until Adobe & FCP accept native H265 or there's a more pro-level converter available. Either way, H265 to prores seems like a big time suck for normal amounts of project footage).

It seems like pulling your keys at 4K and then downscaling the final comp would be the way to go; or downscaling the footage to 1080/444 and then keying. You'd lose resolution but gain full-raster color channels. An A/B test of these workflows would be interesting as well, though I'd predict 4K would be the way to go… though if your other comp plates were only available in 1080 or 720, maybe not?

I just got the NX1, great camera and as a former owner of a GH4 the NX1 is much better. The rolling shutter is bad in 4K but if you are careful the image is just crazy good. here are some 4K frame grabs. Plus I see Samsung will keep fixing any problems people have so there is that as well...

I get the feeling Samsung is really in this to win. ANOTHER firmware update is out, and they've released an SDK for camera control. Meanwhile, the Nikon 7200 announcement makes me respond with a resounding "zzzzzzzz..."

I haven't tried it, but from what I've seen the NX1 is super sharp (like the GH4) and super clean (unlike the GH4, which is pretty noisy). I'm sure someone will test it soon against a green screen, because it looks like it may be the best sub $7K camera for that job right now.

the more I see the more I liked this little cam.

Thanks for all the great replies guys! I purchased the NX1 and it should be here Thursday, I am hoping to do some GS testing over the weekend and see what we can get.

Good choice.
I suggest you to avoid lowering contrast too much. It's an 8bit camera and IMO shows too much banding when you shoot too flat and grade in post.
After many many tests, I've found that the best setting for me is just gamma DR with all other options set to 0.
Also, I recommend you to give a try to rocky mountain converter. I download and tested it yesterday. It's free and it's based on ffmpeg. It does a good and quick job at converting h265. It sounds odd, but converting to prores HQ increases banding on gradients. I find that h264 is better to this extent.
If you don't have a super fast computer, you can always create proxies from 4k h264 files in fcpx for quick editing and grading, then relink to 4k h264 before exporting the final master.
Hope this helps to speed up your workflow with your new camera

Thanks for the advice, I was actually working on getting my laptop set up to convert the files. I was looking at using iFFMPEG or Rocky Mountain Converter. There was a bunch of people that have tested converters over at EOSHD.com and it looks like these two are the best. Thanks for the advice on the settings, I have read a ton of forms and articles and it seems everyone has their own look they want. But I have read some great stuff with gamma DR, I think ill start there for sure.
