Re: Samsung NX1: H.265 and 4k
 

Has anyone shot much in 1080p? I noticing some gnarly issues in high-detail areas. The 1080p is already about as soft as the 6D but then there are these crazy artifacts. Perhaps some sort of noise reduction? There are "smudges" all over the image at times. It particularly is evident around hair and skin-tones.

Re: Samsung NX1: H.265 and 4k
 

I'd much rather shoot in 4K and down-rez to HD. Much better results.

Re: Samsung NX1: H.265 and 4k
 

Yeah the 4K looks great. I need me my 60p though.

Re: Samsung NX1: H.265 and 4k
 

If your TV has a frame doubler (most TVs of recent vintage do), engaging it can make 30p look very similar to 60p.

I do just that with my 1080p plasma and my down-rez'd 4K>HD looks very smooth.

I just got back from BB where they had just mounted the new 65" UHD OLED TV. I brought a couple of 4K projects from the NX1 and it looked superb...including the motion.

Yes, you have to shoot with an awareness of 30p. But done correctly, you should not have any significant issues.

Re: Samsung NX1: H.265 and 4k
 

What if your client does not have the special TV needed for the footage to look proper?

4k is still too much for a lot of post production workflows, especially in H.265 which needs to be transcoded for most NLE's. I think it is important for all manufacturers and software makers to not "drink the Kool-Aid" on 4k. We still need 1080p and 720p way more and often use DVD for delivery as well.

The in-camera downsampling should be as good as your NLE these days if done correctly. No excuse for a 4k camera to not produce stellar 1080p. But you can not lose sight of the fact that this is a still camera.

Re: Samsung NX1: H.265 and 4k
 

Tim, it seems to me that no prosumer 4K camera offers HD shooting that's as good as an HD transcoded copy from 4K. I don't think it's quite as easy to do as you might think.

Either way, it doesn't seem a big deal to me. When I edit, I edit in 4K and then either make a 4K or HD render. Sometimes I'll do both. It doesn't require any additional editing to make an HD copy of a 4K project.

As far as stills go, I find it exceedingly easy to grab an almost infinite number of 8meg frame grabs from a 4K timeline. Very nice & a multitude of possibilities.

Re: Samsung NX1: H.265 and 4k
 

While I agree with a lot of what you are saying, I think calling 4K "Kool-Aid" is over the top and calling on manufacturers and software producers to ignore it is uncalled for. You can go on shooting 720p no matter what innovations there are. More substantively, even if you always deliver at less than 4K, 4K not only gives you higher-quality, lower-resolution videos but gives you more creative possibilities - for example, you can zoom in post, reframe in post and not lose any resolution for the delivery of Full HD. This is not Kool-Aid, this is a real aid to higher quality video.

And as for excuses, what excuses does Canon have for delivering soft and artifact-ridden HD? Being a stills camera is irrelevant (whatever that means). Apparently, as Ken says, it must be harder to downsample in the camera than you think.

Re: Samsung NX1: H.265 and 4k
 

Everybody calm down. I am not speaking ill of 4k. What I am calling Kool-Aid is the idea that all of the sudden 4k will be the center of production and 'who needs those other formats'... 4k is a tool, but is way too early to be the main or only format of quality on a camera imho.

Having a camera that shoots great 4k and sub par 1080p is what I am referring to. This was the case when the HD era arrived and cameras started coming out without an SD mode. Well, the next round of cameras had the SD modes put back in. The makers can't dictate how we need the use the cameras to make money.

btw, being a stills camera means it probably does not have the processing power for video as a dedicated video camera. The mid level 4k video cameras have excellent 1080p as they utilize quality downsampling from the 4k imager.

Re: Samsung NX1: H.265 and 4k
 

Back to a video (4K, sorry):

Re: Samsung NX1: H.265 and 4k
 

Yes, amazing level of detail.

Re: Samsung NX1: H.265 and 4k
 

Hi, Mark.

I'm seeing an occasional vertical smearing at the bottom edge of the frame, usually during a tilt-up from areas of high-density detail, like the grass at 24:09 (see the thumbnail).

I thought it might be my non-4K system choking, but when I downloaded the full-res file from Vimeo, the weirdness shows up when advanced frame-by-frame, in both Edius and Premiere. Any ideas?

.

Re: Samsung NX1: H.265 and 4k
 

Thanks for looking. It appears this artifact is the result of PowerDirector 13, which I have used to edit the clips.

Here is the link to the original clip that has the artifact in the full PD 13-rendered video, converted using the Samsung Movie converter.

https://onedrive.live.com/redir?resi...nt=video%2cmp4

You will see that this artifact is not in the original clip.

The clips for the Vimeo video were rendered in PD13 using XAVC S, at 100 Mbps.

Post 1.3 firmware update slo-mo test from 1080 120p
 

Re: Samsung NX1: H.265 and 4k
 

Thanks for isolating the issue. (And the 1080p 120 is impressive.)

Re: Samsung NX1: H.265 and 4k
 

I'm curious about this cam and I found this footage, and I must say the NX1 is sharper, but as far as color, at least on my screen, it's a match.

Re: Samsung NX1: H.265 and 4k
 

Quick question:

Does the 120fps recording mode have the ability to record audio? Or is it an overcrank mode without audio.

Thanks.

How effective is the AF with the new firmware? Although my intent was not to 'test' it at an event like this, but rather capture some interesting footage, it nonetheless does show how well Samsung improved the AF.

All shots are straight from the camera, edited in PD13 and shot with the 18-200mm lens.

Select 4K if you have the ability to view on a 4K or UHD monitor.

Re: Samsung NX1: H.265 and 4k
 

Looks very nice on a 4K monitor! Samsung seems to have done a pretty good job at producing good sharp 4K images, anyone try their NX500 (the baby bro to the NX1)? Been contemplating that one as a "pocket" camera, seeing as Samsung seems to be at least as much on top of 4K, if not more than the "big boys".

I'm happy with the Sony AX100, but getting a tad tired of waiting for a 4K update to the RX10 or any of their other still (Alpha) cams for that matter

Re: Samsung NX1: H.265 and 4k
 

Thanks Dave. Things improved quite a bit subsequent to the last firmware update.

The AF performance was significantly improved.

Re: Samsung NX1: H.265 and 4k
 

The NX500 does fine in 4K UHD, and the crop actually is useful:

Re: Samsung NX1: H.265 and 4k
 

All the footage I've seen from the last couple videos posted on this thread are incredibly sharp and crisp and detailed. Amazing resolution,but the overall feeling is so video and digital.
Can anybody who has posted some of the footage try to pretend they're filming a 30" narrative and try to be as cinematic as they can? It's just that for me, and I'm mainly interested in shorts, this cam seems so harsh and blunt.

Re: Samsung NX1: H.265 and 4k
 

Thanks Larry...I think. :)

Mark and I have very similar styles of shooting and, speaking for myself (and I think for Mark), it's that 'you are there' look that we so love.

I always try to replicate the look & feel of what I'm shooting and for me that pushes me toward the look that you probably don't like, video.

Re: Samsung NX1: H.265 and 4k
 

Fair enough. I'd say, hooked to a light gimbal stabilizer this is the cam for a doc, no doubt.

Re: Samsung NX1: H.265 and 4k
 

Re: Samsung NX1: H.265 and 4k
 

...what about the steadicam solo with the NX1 ?? ... any toughts ??

Re: Samsung NX1: H.265 and 4k
 

Mark, the videos using the NX500 are really nice. What is in your lens collection for this camera?

Re: Samsung NX1: H.265 and 4k
 

Thanks. The 16-50mm PZ, the 60mm Macro, the 50-200mm zoom, and the 16-50mm S (for low light).

And now the Samsung NX500 is almost a Pocketable NX1
 

With the recent firmware update, so that 4K has 70 Mbps H265 bitrates and there is improved AF in video mode, the NX500 is more like a little NX1:


I had no trouble seeing the lcd image on this bright beach.


I took advantage of crop mode.

Re: Samsung NX1: H.265 and 4k
 

Very nice, thank for posting this.
What lenses are you using?

Re: Samsung NX1: H.265 and 4k
 

You are welcome. One lens (I have to travel light): the 16-50mm PZ.

Re: Samsung NX1: H.265 and 4k
 

Re: And now the Samsung NX500 is almost a Pocketable NX1
 

That is Strelitzia reginae, also known as the bird of paradise flower. It comes from South Africa.

Re: Samsung NX1: H.265 and 4k
 

Another nice footage. Thanks for the lens.
One day, when and if you have time, I'd like to see how cinematic the NX1 could be. Do you have CineConvert by any chance? Have you tried to play with the footage in post to make it more film like?

Re: Samsung NX1: H.265 and 4k
 

I'm truly impressed with the Samsung NX1. Although now it is 2017 and the same limitations that existed a couple years ago no longer exist. Like codec issues with the H.265. Now today it is very easy to edit and grade the footage. Here is a little quick video I did to give some idea of how easy the footage is to customize to your liking. I have also included a free lut and the link is also in the YouTube Video description.

Free Samsung LUT: Samsung Basic Lut - Lifted Blacks

I have also been able to use with the Zhiyun Crane with no problems. I use the Samsung 16-50mm f/3.5-5.6 lens because of the light weight and the autofocus works awesome.
