Yes, my fault ! I used the wrong file (the H.264 and not the original .MOV as I thought...) :expressionless:
I made another test of color grading and no macroblocking or banding. Also this time I have not used a LUT to "delog" but I did it manually.

 

In the sky in the second clip that is "graded" clip there is an absolutely horrible band of colored noise in the sky (upper left). I got the same result when I used the official Sony REC709 LUT from Sony Catalyst (which automatically recognizes the clip as S log 3). This is totally unacceptable.

It's funny because I don't get the IR pollution that people claim comes from that camera. I think it just depends on the week of manufacturing. I doubt this will be the case on an A6300, which is not really a cinema camera.

The ir & uv cut makes magic you should see the tests. I'll probably use it with the a6300. It can always be fixed in post but better to do it on camera. But for sure on a6300 it's not as bad as on bmpcc

I don't know if there's aliasing with this video from imaging resource that is shot at 30p.... But what stand out really well it's the totally absence of aliasing at 25p, nothing less that ideal line.... I'm watching files with my 4k tv

If I scale down to 1080p the results are gorgeus but a bit of aliasing it's always visibile even using different scaler like lanczos, area, bucubic etc etc..

Am I the only one seeing a fair bit of moire and aliasing? Maybe its the resolution im viewing it at..

There was a bit at 4k, but you know, youtube. I would be shocked if there was none in the railings in between the garages though, I wonder if the garage door is present in the origional.

youtube 4k footage on 1080p = moire on all cameras. watching the 1080p on  a 1080p will be alot less moire.

The clip on vimeo shows that the clip on vimeo shows some banding. More interesting is, that your own grade with the original footage showed the same banding.

Can you you share a screenshot of the histogram or waveform monitor when this is happening as I really like to see how you were able to do that. I too am able to get banding, but only when I let the waves on the waveform monitor leave the assigned space within the diagram.

"Samsung NX1 does not use a crop of the sensor – it pixel bins from the full area of the chip, although it does have a bit of aliasing and moire"

You get aliasing and moire from line skipping, not pixel binning. Those are two distinct ways of reading out a sensor. :)

What are you guys watching these clips on? I'm watching on a 4k monitor and the only moire in that clip is a tiny bit in the fence on the left between the buildings that's behind the palm trees and the big rock. The door is clean. And I'm not seeing any aliasing at all.

For those that don't have a 4k monitor and keep talking about all the aliasing and moire, here are a few screen caps from youtube and vimeo, feel free to view them at full rez.

Yes Andrew, some of us do see 30p as a viable creative option.

If you are not considering 30p as a creative tool, then you are missing out.

For all those who have tested the A6300, are there any overheating issues in 4K, HD and 120fps mode?

does anyone know if it`s possible to shoot in a log profile and have the display set to rec.709?

Directly in-camera I don't think so. But if you use an external monitor like those by SmallHD you can load a LUT and display a Rec.709 version of what you are shooting.
