DIS can't be used on non Samsung lenses right?

Does DIS work OK with higher bitrate or it doesn't affect it in any way?

Well, IDK yet dependences between real record algorithms in NX1 and any of tested parameters, maybe I'm totally wrong, but for me it seems that random 4kb write tests shows far more consistent results to actual allowed bitrate, than vendors "write speed ABC Mb\s". It is just theory proof test, I might be totally wrong on that.

But again, vendors write speeds is total BS for NX1 4K record imho. Maybe it is a NX1 thing, yes, but Blackmagic's document actually provides some proof of that not only NX1 have this troubles.

I see, you could try with this tool https://www.attotech.com/disk-benchmark/ and check if you see a pattern. There must be a block size used while writing files that could explain the "slow" speeds.

SD card speed depends a lot on the controlled used by the reader/host. And of course the kind of test you're doing.

@outerbeat when you record video the camera will use sequential writes not random 4K why are you interested in that?

Now I have another question. Is there a way to develop smartphone apps or web apps for the NX1? Or directly "apps" on the NX1?

I want to develop one.

We do not now how it it would look like in 4K (according some comparsion 2.5K look a little worse than 1080p). But I still think that NX1 has similar low light performance as A6300 in photo mode (or even better), so problem is in processsing of video (NR, codec?, I do not know...)  which is not so good.

Not sure what to say at this point.

Kino Seed just posted video of 2.5K video without noise reduction - http://***URL removed***/forums/thread/3990893?page=2#forum-post-57632926

Noise grain is very visible here, but we should realize that it is quite high ISO (6400). I think it would be more usable and subtle in 4K.

It is proof that noise reduction is not built-in the codec - really great news I think.

Vasile/Otto - is there any chance if 4K could be inserted into slot for VGA? Maybe then 4K would be without NR.

I am wondering how it would affect 1080p modes which suffer with high NR above low ISO.

I'm not sure how he turned NR off on the nx500? I'm downloading the video file now...

UPDATE: I've seen the video, well the noise is definitely there but it's there in a way that makes me think it's the sensor design that it's not good in low light. Agreed that it's 6400 but isn't the a6300 clear at that ISO? Even the Nikons at 6400 don't look that bad.

how do you use them with the nx1 without slog?

It is a shame to have a camera in 2015 with usable ISO at only 1600.

It seems that you have to have NX500 with 2.5K (+bitrate) hack :-) .

I hope that it will lead to 4K/1080p without NR for all modes in NX1 (NX500)

I meant from the samples you linked?

Hmm, it seems that 2.5K mode is without noise reduction -  http://***URL removed***/forums/thread/3992683?page=2

What do I have to check to see this?

This is not quite the right place, but still warrants the question: is this an official Samsung ad? This is the first time I've seen it, and the video in it looks very clean. 

It is it was on YT with millions of views and they removed it.

I hope NR is not built in the HW...

Well 120p is where we should see the best improvements since the bitrate really suffers there. It's not the NR.

Does the bit rate increase apply to 120p?

Just live from chat support. They know nothing about it for the big guys are still keeping this hidden.

Samsung is not discontinuing the Digital Camera products. Samsung has no statements on it.

I wonder if you ask Samsung support now about this if they still have the courage to deny.

So it seems that bad quality at high ISO is not the bitrate but the NR inside the camera.

Anyone tried if there any improvement on 3200 ISO and beyond with higher bitrate?

let me be the first to say THANK YOU! The download site does not appear to be working. likely because a bunch of people are trying at the same time lol.

Just out of curiosity what is the original Mbit/sec of the NX1?

Pro is 80Mbit but with that script it seems you can go till 320mbit.

We don't even know if the nx1 benchmarks does random or sequential reads. Or if it's threaded. It's complicated.

yup and even though size will raise a lot it doesn't matter since sd card are so cheap right now

ok thanks... anyway don't be offended but isn't time limit removal the last of our concerns right now? I can't find a reason to use such a powerful cinematic tool to record for such a long time

I wonder why internal storage is so slow...what if we try to enable swapping on the sd card? with fastest cards it shouldn't be a problem I guess

hasn't someone tried to solve this corrupted file thing disabling power saving mode in the dev menu? maybe I've dreamed about it

there must be a point when even hevc shows fine details right?
