I figured since prefman has a topic I would make one for “ST”.

There seems to be quite a few interesting things that can be done with this command particularly in the cap function. https://github.com/ottokiksmaler/nx500_nx1_modding/blob/c05a707fe540a086877cb1c1d103c466f25b2ed2/ST%20Commands.md

Has anyone played around with this command a bunch?

I have played around with it a bit but I am not very good with all this stuff so it takes me a lot longer than perhaps some others, plus I do not have a lot of free time to mess around with(though I am sure this is the case for most people on here).

You know what Samsung should have done. Used the m4/3 mount.

Its free to use. It covers the sensor. Many MFT lenses cover the whole sensor, some would be good for crop mode. Their own lenses would have been very popular among GH4/e-m5/etc users. More people would have taken the plunge or bought the nx500 as backup.

I would have much preferred for meta-bones to just have made a speed booster for EF.

Would any of you invest in a consumer level steady cam now that we have such affordable 3 axis gimbals?

My thoughts were always that I do not want a "cheapo" 3-axis gimbal and for the money to get a good one I could get a REALLY good steadycam + tripod + monopod + fluid head and a decent slider and this set-up would be more versatile but it now looks like you can get pretty decent gimbals for quite cheap now.

Also side related question has anyone used a mnopod-steady cam combo? are they any good or just gimmicky?

The NX1 mounts itself as mass storage via USB at the moment, I think without some serious reworking of the internal Firmware it wouldnt be able to support a storage drive. It would have to be programmed to mount the drive, recognise it as a storage device and then be given the ability to transfer the footage from the SD to the USB, without any external software or hardware. The NX1 may not have the hardware capabilities to achieve this, even with the software, as a mass storage device, its the computer thats doing all the transferring legwork. Even then, it can charge via the USB port, but I doubt it could power a device from the port.

Extremely good points. Especially regarding the power requirement.

Worth trying? I just went to two stores and neither of them had a cable that would work.

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?

Has anyone tried to plug an external USB drive directly into the camera and mount it using telnet? I cannot find anywhere if the USB 3.0 on the NX1 is an OTG port.

I was planning on going to pick up a micro USB 3.0 to female type A and play around with it but if someone already has the required cables and knows more about Linux than me this would be alot faster. I would just be googling commands from the internet https://www.google.ca/search?q=how+to+mount+a+usb+hard+drive+in+linux&oq=how+to+mount+a+usb+hard+drive+in+linux&aqs=chrome.0.69i59l2.1280j0j7&sourceid=chrome&ie=UTF-8

The intended purpose would be for a program that would back-up all the contents of the SD card to an external drive. This would allow us to back-up our videos(a must with only 1 SD slot) without bringing a laptop to every outing.

Yes you can use the same method.

For shutter speed the offset is 0x00000310 on the NX1 which is "0x00000310    0004    APPPREF_SHUTTER_SPEED_INDEX"
so to set the shutter speed to 1/100th you type the following:

prefman set 0 0x00000310 l 107
prefman save

the 107 value was obtained by manually setting the shutter speed and then doing a

prefman get 0 0x00000310 l

I have tested it and it works.

Could you please help me out? If you can't help me that is ok, I will just play around with it later this week when I have time but if you could it would be great as I am sure what you could do in 5 mins would take me 3 hours to figure out lol. Does the last three lines make sense and will it work? I am just piecing things together from what I have seen and really have no idea what I am doing.

EV_RIGHT.sh

prefman set 0 0x00000330 l 2
prefman set 0 0x00000310 l 91
prefman save
dfmstool -s 'osd string 7 UHD 24p'
sleep 3
killall dfmsd

EV_LEFT.sh

prefman set 0 0x00000330 l 4
prefman set 0 0x00000310 l 128
prefman save
dfmstool -s 'osd string 7 FHD 120p'
sleep 3
killall dfmsd

Also is there a command to put the camera into video stand-by?

I actually had both out when you asked, so I tested it with a lamp... and I couldn't get it to flare for the life of me. It is sharp and contrasty though. I have to stop using the NX500, every time I pick it up, I am so impressed with the ergonomics of that camera and how light it is. If I just liked the clinical look it shoves onto its images, I would keep it and get rid of the G7. Good luck with the OM 50mm!!!

Too bad regarding the flare but I guess It would be better to have the option to add a flare in post(tho I probably never would) then have an unwanted flare when I don't want it. I can't remember what lens it was but I was once playing around with a friends camera and the lens was constantly flaring. I swear it would flare even if the sun was behind you lol. I am pretty sure it was a Nikon/Nikor F mount lens and it was on a 60D but this was quite awhile ago.

Found a way to commit changes made with the st commands and prefman, just do a prefman save, see this link to see how I switch between 4K with DIS on to 1080p @ 120fps with DIS off via shortcut keys.

http://***URL removed***/forums/post/57551639

This is excellent. Thank you so much this is what we were talking about. any luck with changing the shutter speed as well? From what I understand the st command can do this.

I have used it once or twice with my NX500 (which I'm selling) and it's a nice little combo. The OM lenses are very contrasty and sharp. The 50mm 1.8 are very cheap on eBay and there are a ton of them. I also have the 28mm f2... a beautiful little lens (am selling that too) They're great lenses, I just already have waaaaayyyyy tooooo many lenses, so some have to go.

That is good to know. The guy is selling his lens for $40 CAD witch is pretty good considering the adapter is going to cost more than that lol.

How is it for flaring? I love a high contrast super sharp lens flare... J.J. Abrams style lol.

The cost to continue production of the NX lineup > The potential revenue + the cost of losing all existing NX costumers

No amount of petitions or social media presence is going to change this formula witch is what samsung is looking at. If I were samsung I would be doing the same thing.

It is a shame tho the NX1 is an amazing camera. One that I have been using for over a year now and hope to use for another year or two depending on what the other camera offerings are in a year.

Personally I am kinda holding my breath for the GH5. I kinda miss the ergonomics of my GH2. I am kinda worried about going back to a smaller sensor tho but anywayy I have another year to think about it.

Funny that you guys posted this today.

The Best Buy near me in Vancouver (Grandville and Robson) has a Samsung feature department/section where they have all their phones, tablets and TVs on display. It is seriously bigger than the apple section and they have one small case where they had 4 or 5 lenses and an NX30 on display for the longest time. Even after Samsung cameras left the Canadian market the display was still there for months. Anyways I was in there yesterday and the display case is now empty. Lol everyone panic…. Your NX1 is going to stop working immediately especially with adapted lens.

On another note I am meeting with someone tomorrow to look at buying his Olympus OM 50mm f/1.8. Anyone use this lens on the NX1?

I am skeptical that it is an apple issue. I'm pretty sure the file produced by the NX500 with the 1080p120 setting is messed up. I have never had any issue decoding any other NX500 clip (even on my brand-new-top-of-the-line-piece-of-shit apple machine that I shouldn't have bought because "really - it's a mac").  I know that variable bitrate can be good, but jumping from 2MB/s to 380Mb/s and back when the only thing changing in the shot are a few falling snowflakes does not seem like a good management of bitrate.

Here are two test files straight off of the NX500's card: http://www.filedropper.com/lastleavesnx5001080p120test

Compressed video usually only records the change in pixels compared to a reference frame.

http://www.axis.com/global/en/learning/web-articles/technical-guide-to-network-video/video-compression-guide

So a very detailed scene could have the same bitrate as a pure black scene as long as nothing is moving in either. Every few seconds a new reference frame is encoded witch would cause the bitrate to jump especially in a very detailed scene.

Honestly I am a pretty big noob when it comes to all this stuff and there are a lot of people on here who know and understand this stuff alot better than me but this is how I understand it.

where i said someone own me something? All im saying that all i see is 2 people doing something-rest just waits. How many of you looked at source codes? Only me? We cant wait for others to do things, as i get suggestions to  we must work together and all.  Now im comparing kernel source differences between NX1 and NX500.

Kernel config file have option like CONFIG_MACH_D5_NX1 so easy to search source files and see what changes in code depending on this condition met or no. SO far trying to see is there any CPU related differences.

That is really cool. Keep up the good work. Me any alot of others thank you for your contributions but unfortunately there is not much I can do to help.

I am good at many things but hacking is not one of them. Do you need me to build or maybe climb something? Or perhaps I could film something for you? I am quite good at those things  

P.S. I did spend over 3 hours looking at the NX1 source code and found some interesting things (see earlier post from like 2 months ago) However I really have no idea what any of it means or how to do anything with it.

What type of LED cause a strobe in the nx1? I can't find anything about this. Can you go into more specifics? I'm about to buy some lights for interior shooting.

I do not think this is an issue with the NX1. This is more of an issue with having too short of a shutter speed. this is almost inevitable with 120p and even 60p if you are following the 180deg rule.

Mountneer, I asked for such a shortcut some weeks ago. I'd like to be able to access thes evideo modes at the press of a button:

A) 1080-120-1/250-ntsc-no dis

B) Uhd-25-1/50-pal-dis

Wouldn't it also be sweet if it would also adjusted the ISO and aperture to keep the same exposure after setting the shutter speed to 1/250 or 1/50?

In terms of the whole "Return to photo" option I mentioned above, I could do without and after thinking about it i don't really think I would use it that much.

What would happen if you want to suddenly multiple photos in a row? You would have to remember it hit the specific button combo sequence before you wanted to take the photo or be forced to press the shutter twice every time you want to take a photo. 

I do not understand what you mean. The issue you are describing exists with or without this proposed program. If you are in video stby and want to take a photo, you have to half press the shutter to exit video stby then press it again to take a photo.

I was not thinking that this program would lock you into video stby mode if that is what you are thinking.

Their are two things I am trying to help with.

1. If I am recording a video and want to take a picture I have to change the shutter speed to something more realistic for a photo like 1/100 then set my aperture to suit then possibly change the ISO as well. Similar problem but in reverse for going from photo to video.
2. Also quite often I find myself filming something and then suddenly want to quickly change to 120p to capture something in slow motion and right now I have to go into the menu to change the resolution then change the shutter speed, aperture and ISO to suit witch is quite time consuming.

Actually I was just thinking about it and you could instead of storing all the values in files on the SD card and retrieving them you could have the program check the current f-stop, shutter speed and ISO and then calculate the appropriate f-stop and ISO to have the same exposure but with the shutter speed set to 1/50.

Technically what you want already exists except it does not save video mode settings which is exactly what you want, it only saves the settings for photo mode.

Custom mode on NX1, same for NX500: http://www.samsung.com/ca/support/skp/faq/1078522

Agreed, My original preference would be to be able to save the video resolution and PP in the custom mode settings but from what I understand of the hacks up to this point there is no indication that is easily doable. the Program I am proposing seam to me to be relatively straight forward.

I just got back from a trip to Spain and while there I found myself taking a lot of photos (more than usual) and switching back and forth between photos and videos became really annoying and got me thinking.

Is it possible to write a program like focus stacking one that when you push a combination of buttons it pulls up a menu with the following items that would perform the following tasks?

1. 3840x2160 24p
    - Record the current Shutter speed, aperture, ISO and WB into a file named “photo” on the SD card
    - Set the video resolution to 3840x2160 24p
    - Set the shutter speed to 1/50
    - Set the ISO and WB to values that are stored in a file named “3840x2160 24p” on the SD card
    - Enter into video stby mode
2. 1920x1080 120p
    - Similar as above except with different shutter speed, video resolution and ISO and WB from a file named “1920x1080 120p"
3. Return to photo settings
    - Check to see if the video resolution is set to UHD or HD and save the ISO and WB setting into files “3840x2160 24p” or “1920x1080 120p” respectfully
    - Restore the shutter speed, aperture, ISO and WB settings from file “photo” on the SD card.

I thinking this program would speed up my process of switching between photos and video and could even include things like different picture profiles for each resolution.

What does everyone else think? Is this possible to do using the st and prefman commands and is it even worth doing or is this not going to be useful to anyone but me?

Watch the video, its easier for all of us yeah? Like I said, if you want to smoothen out motion in clips separately from what is not moving, good luck.

I understand the principles of shutter speed (and traditional shutter angle). What the video doesn't address is the ability for some cameras to "replicate" a slower shutter speed than frame rate. eg. 1/10 sec x 24fps = 2.4sec worth of exposure every second = physically impossible

10 hours ago, tugela said:

Not really. Just offset duplicate copies of the clip by one frame and set the transparency to 50% (or whatever fraction you are using to simulate a longer exposure). Shoot with the shutter speed set at whatever the frame rate was and you are good to go. It's pretty simple.

I did a liltle more research and my assumption and what you mention appears to be correct in that if you want to do this its best to just do it in post with the method mentioned above or similar.

Unlocked shutter would be a great thing. Mainly because I want 1/48 as an option in 24p for a true 180 shutter. 1/50 is close but not the same.   

This is actually a really good point. Has anyone tried to force 1/48 of a second using the "st" command?

It just exposes each frames multi times

 

I did a quick google search and found some info on this but not enough to satisfy me and I am quite interested now.

Do you know exactly what is happening in camera when you have a longer shutter speed than frame rate? I mean it is obviously impossible to expose the sensor more than once at a time so the camera must be doing some math internally witch makes me think that there is no reason you cannot achieve the same results in post. I suppose the camera is likely using the raw sensor data where when done in post it would be using the compressed codec data.

I would not take advice on anything from vloggers, much less about cameras. /rant

I wouldn't say that. There are some really good vlogers out there that are making some really good content on a really regular basis and IMO content quality trumps IQ every time.

Its way more important whats in front of your sensor than the sensor itself.

P.S. i would like to add the caveat that there are alot more vlogers making HORRIBLE content (atleast in my subjective opinion) than volgers making "good" content but there are still some good ones out there that I think we could all learn a lesson or two from  

I have never heard of setting the shutter speed to lower than your fps. How does this work? does the camera split and combine the data from each 1/10 of a second for multiple frames?

I'm mostly poking around and finding out what Samsung engineers already made but is not exposed through standard menu or keys. This is nowhere near actual "firmware hacking", but there's some useful stuff there.

I'm actually trying not to hack the firmware. I'm just too afraid to end up with even the nx500 sized brick  

I have not tried any of the hack yet but I agree that I would prefer to not touch the original firmware and not need to flash anything to the cameras internal memory.

IMO the idea hack (if possible) would be somewhere in between what both of you are doing with the ability to reboot into a separate OS from the SD card.

Chant, from what you have seen do you think it would be possible to do this or do you think you would need to flash something new to the camera?

It might be better to split into two topics, nx500 and nx1. Or front end and back end.

OttoK has a really good githud that he is updating regularly. Perhaps you could start a githud page for what you are working on (back end NX1 stuff). Even if its more of just sort of "blogish" updates at this point. I believe github is free but I honestly don't know. 

I am extremely excited reading the progress both of you have been making :). Keep up the good work, both of you.
