Otto K Posted March 7, 2016 Share Posted March 7, 2016 @sandro there are plenty of tutorials on https://github.com/ottokiksmaler/nx500 including the archive you should unpack to SD card for telnet, etc. sandro 1 Quote Link to comment Share on other sites More sharing options...

Adobe premiere afaik doesn't support hw decoding of hevc latest update of adobe cc2016 does. Davinci's latest does as well I have downloaded sd.tar and follow instructions for customizing keys (https://github.com/ottokiksmaler/nx500/blob/master/Customizing%20keys.md) but it seems that NX1 do not want to load it. Boot takes same time and I do not see any green dots and text "IP..." after pressing EV+MOBILE. ------------- EDITED: I can see the green dots with IP ADRESS sign (after change content of nx_cs.adj file to "shell script /mnt/mmc/scripts/EV_MOBILE.sh" ) but EV scripts still does not work.

I couldn't get the NX1 to trigger anything with the EV+ button either. you can change the contents of your nx_cs.adj file to say "shell script /mnt/mmc/scripts/EV_MOBILE.sh" this will run the EV_Mobile.sh script at bootup, when you get the green dots go to settings and configure/connect to wifi or you will not get an ip address to connect to.

sandro Posted March 7, 2016 Share Posted March 7, 2016 I seriously don't get they the nx1 is do bad in lowlight while the a6300 can do this I mean there something wrong with the sensor design or we really need to remove that NR. nougat 1 Quote Link to comment Share on other sites More sharing options...

Sony a6300 is newer and uses s-LOG2, its not a fair comparison. Also its obvious HEVC + NR doing something stupid, we all know video mode have NR by now. However if you take a picture at 3200ISO, there is no blue streak ISO artefacts like in video. So its clear that its the NR and in-camera processing causing these artefacts. You might argue 28 megapixels versus line skipping, but even at the highest ISO I cannot see these streaks, something is going on with the in-camera processing of the video. And we need to shut it off because the 3200 ISO looks usable if the stupid NR just "#&&%¤ off. kidzrevil and Beritar 2 Quote Link to comment Share on other sites More sharing options...

Funny thing is as mentioned by you guys shooting at high iso is fine with raw stills. A little noise reduction I can hit 6400 Quote Link to comment Share on other sites More sharing options...

The issue of nx1 at iso 3200 in video is, imo, nr. The raw pictures at iso 3200 are totally usable, especially when downscaled to 16mp or below. Hence at 8mp they should shine! Instead, video at 3200 is very poor. Hence, there is something 'wrong' going on in the process. Beritar, SMGJohn and kidzrevil 3 Quote Link to comment Share on other sites More sharing options...
chauncy Posted March 8, 2016 Share Posted March 8, 2016 I remember this review. It''s dated and most of the issues have been fixed. But the reviewer makes a definite point about the huge noise gap between 1600 and 3200. Calls it falling off a cliff at 17m 25 sec in. https://m.youtube.com/watch?v=1flm65f2Gy8 Quote Link to comment Share on other sites More sharing options...

Hence, there is something 'wrong' going on in the process. One more thing related to possible NR: Just take a look on photomode when you have set higher ISO - it looks same as 120fps above ISO 200 and 60fps above ISO 400 and 30fps 4K above ISO 1600. I do not know, but I think that "noise reduction" is related to some hardware glitch (higher frequency of sensor - higher "NR"... ?). But I really hope that it is real noise reduction that could be removed by hacking... Quote Link to comment Share on other sites More sharing options...
sandro Posted March 8, 2016 Share Posted March 8, 2016 I wish it can fixed but i really have doubts. Why would a nr bring blue lines? It seems more like something produced by electronics/hardware than a software thing. Quote Link to comment Share on other sites More sharing options...
Popular Post Chant Posted March 8, 2016 Popular Post Share Posted March 8, 2016 Good news, bad news. Good news is that I have learned a lot about the srp( samsung reconfigureable processor) architecture. Bad news. It is very very very very complicated. Machine compiled c into binary. Unknown yet when it is loaded into the firmware and if the .cpp files that are listed are infact that, or just other hard ware controls So the srp is like an fpga in the way you can change what it does on the fly. It differs in the way that it uses VLIW instead of bits to do its magic. Reverse engineering the binary into something workable.. is possible, but time will tell if and how much can be changed. The plus side of a simple isp changing values in softwear can do something like what the gh2 hack did. The downside being you are stuck with the hardware. The plus side of the srp implementation.. Building a custom algorithm to..exchange the hevc codec with something else.. Could be possible. Unknown yet if the nr is a part of this or just a software implementation. Also if the rumors were true about the ml guys approaching samsung, this would be why it didnt happen. They dont release the srp compiler. One instance of them giving access to it at the SAIT school in Korea is all I could find. very very proprietary. But the dream for me of having a cheap 14bit 6.5k red competitor is what keeps me going. The confirmation of the UHS-II bus sweetens the deal. Going to investigate the possibility of a SD-SATA converter.. I wouldnt mind having a 1tb ssd attached to the back of the camera. TL:DR This camera is complex and things are not getting easier but still progression is being made.

Chant Posted March 8, 2016 Share Posted March 8, 2016 Just now, sidi said: I agree as long as the recording limit is removed. That is something that would be very simple to remove compared to what I just explained. A secondary task though, first we get to the good bits, and everything else is second. The way the srp even loads in is something that isnt well documented, let alone on a camera. saintsimon2016, samuel.cabral, kidzrevil and 1 other 4 Quote Link to comment Share on other sites More sharing options...
