I have to say that I shot it in 0-255 luma range, maybe it would be better with 16-235... Quote Link to comment Share on other sites More sharing options...

I have changed luminance levels in Premiere from 0-255 (1st image fom the left) to 16-235 and some compression artifacts disapeared, even I have pushed contrast and black level higher to prove if there are really gone (3rd image) Quote Link to comment Share on other sites More sharing options...
Pavel Mašek Posted April 18, 2016 Share Posted April 18, 2016 DR of 180Mbps footage. Great thing is there is no macroblocking in lifted shadows, just litle lack of details... but still very good result I think. BTW - First image is unedited 0-255, Standard, MBL +8. Second is converted to 16-235 with some grading (also added saturation becuase there was lack of colours in shadows and just a little bit sharpness to left side of image) saintsimon2016 and Hanriverprod 2 Quote Link to comment Share on other sites More sharing options...

vaga Posted April 19, 2016 Share Posted April 19, 2016 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. Quote Link to comment Share on other sites More sharing options...

Moreover - it is screen grab from in-camera timelapse so it is not so static scene but quite complex with fast moving trees, waves and clouds. There was some small macroblocking in blue parts but they disappeared after conversion to 16-235. vaga 1 Quote Link to comment Share on other sites More sharing options...

I've been shooting with raised master pedestal around 8-9 and it helps alot. Im gonna install this hack today and shoot some clips. Raised pedestal + increased bits to the shadows should work wonders with underexposed footage Quote Link to comment Share on other sites More sharing options...

No it raises or lowers the black level so a +8 mp uses the 9-255 range and a 15 mp uses the 16-255 range of data. The 0-16 range of data is usually the "garbage" area when it comes to in camera compression. I spoke to visioncolor and thats why they use the 9-255 range for their visiontech profile and I assume thats why technicolor cinestyle uses the 16-255 range. Use normal gamma to avoid banning and adjust your blacks in post. The results are great especially at high bitrate Quote Link to comment Share on other sites More sharing options...

I will try it, I started just shooting with the picture profiles in the camera and I got some pretty great images out of it, I will use the master pedestal more now that I actually know it affects the 0-225 range Quote Link to comment Share on other sites More sharing options...

AaronL Posted April 27, 2016 Share Posted April 27, 2016 I would like to see the video without that annoying slow-mo effect. so needless. other than that it looks nice! Quote Link to comment Share on other sites More sharing options...
kidzrevil Posted April 27, 2016 Share Posted April 27, 2016 160mbps with heavy grading and no noise reduction. I was trying to see if I can push the Samsung nx1 to macroblocking with a heavygrade. No macroblocking, so far so good. Let me know if you notice anything odd Quote Link to comment Share on other sites More sharing options...
kidzrevil Posted April 28, 2016 Share Posted April 28, 2016 I regraded the video. This time I removed the film grain for better compression and added a slight gaussian blur to alleviate the sharpness. Definitely gave me a new love for the nx1 Quote Link to comment Share on other sites More sharing options...
MountneerMan Posted April 29, 2016 Share Posted April 29, 2016 Has anyone did any testing with increased bit rates in 1080 120p? Quote Link to comment Share on other sites More sharing options...
Marco Tecno Posted April 29, 2016 Share Posted April 29, 2016 mountneer, since tomorrow I'll have to fikm my daughter at her first essay of rhythmic gymnastics, indoor, with lights and I'm in Europe, I did several tests at 100fps@180mbit/sec (pal). I think the results are very good up to iso 400, decent at 800, bad to very bad at 1600 and up. I'd rather use 1/100 (instead of 1/200) but won't go beyond iso 800 at 100fps.

I personally hope they manage to disable the NR because I did some downscaling and tests with the ones they already uploaded and even though the ISO is worse at lower resolution compared to 1440p and 2160p it still is superior to the old 1080p footage with the NR in place.
