I'm not sure if it's because I've finally upgraded to the paid Studio version of Davinci Resolve, but my NX1 footage plays flawlessly... YES! No more transcoding to DNxHR and ProRes... hot damn. This frees up a LOT of Hard Drive space. I'm using Davinci Resolve Studio - Public Beta 2 I maybe late to the party here, but this is great. My hacked NX1 with NX-L speed booster still holds up great in 2019. The dynamic range is a little weak, however the detail retention is awesome.

@homestar_kevin, I've been using the NXL on my NX1 and NX500 for well over a year now. I've never seen that error in regards to taking photos.

My Samsung NX1 is still rocking strong in 2018.

Interesting... I thought the whole camera shutdown when the usb cable was plugged in. Never tried that... As a side-note, in my experience the NX1 batteries last a pretty long time, around 2 hours or so.

Darn... did I miss it? What's a $10,000 Samsung camera look like?

For those using a PC with Windows, I highly recommend Dali Mustache for converting NX1 footage. It does a great job capturing the full data range of your original files. I purchased a licensed version, but the only limitation on the free trail is converting one file at a time. I convert my NX1 footage to DNXHR HQ... it's a little overkill, but I don't want to loose anything. http://hdcinematics.com

Hey guys, sorry I'm back. @Marco Tecno Monitors do not work well for shooting stills on the NX1. The reason is the hdmi port puts out a low resolution image until you're actually recording. Frankly I wasn't impressed with this monitor till I actually hit the record button... suddenly the image was tack sharp. Also, you can't zoom in on the images without hitting buttons on the monitor... the more I think about, using a monitor on the NX1 IS TERRIBLE FOR SHOOTING STILLS!!! Also, the monitor has it's own focus peaking mode. @capitanazo The monitor works with the nx1 while recording in 1920x1080 at 120 fps. I shot some high speed footage earlier this week and didn't have any problems with the monitor.

Hey gang, earlier this week I tested out my new Lilliput monitor as part of an old fashioned blackbird steadicam rig. This monitor is AWESOME!!! I can clearly see and pull focus with my manual lenses. The image is great when you are recording. Since this thing is so cheap, I thought I'd share it.

The NX500 kit lens isn't bad. It's only got nine lens elements and goes pretty darn wide.

Brian, I can't comment on the improvement for the NX500 before and after the hack. With the bit rates, it really seemed like a no-brainier. Although the Samsung codec is superior, the stock bit-rates are still to low for getting the most out of the 4K resolution. I've heard plenty of GH4 owners complain about the 100 MB on their cameras.

I'm failing behind on this thread. I've got a couple more videos. This crazy video uses... FOUR cameras. Editing was really challenging but the final product was worth it. We have the NX1, NX500, and two high-end samsung cell phone cameras. The NX1 is using the NXL speed booster here and below. And more recently, here's a good video shotguns filmed at our indoor range. This is using my usual NX1 and BMCC combo. Some of the NX1 footage was under exposed, but I was able to fix it post without any problems.

Nice. 120 fps is perfect for this.

For good classic manual lenses I'd recommend getting a old Pentax M42 adapter and picking out a 35mm lens to your liking. There are many good lenses out there to choose from. Meanwhile, can't help with audio. I haven't found a mic combo I like yet... but you'd want a short shotgun mic with a hot signal I think.

Got something interesting here for fellow videographers in the later half of this video. The first part is just general run and gun footage from my NX1... a mix of 4K and 1080p at 120fps, slowed down to 24 fps. I can't remember the lenses I used there... but for the talking head portion I'm using my new NXL Speed Booster! I'm using my dual camera rig for the interview portion with the same lenses on both cameras (BMCC 2.5K and NX1). Each camera has a Super Takumar 50mm F/1.4 lens with speed boosters. Mitakon Lens Turbo II on the BMCC. The custom NXL Speed Booster from Italy on the NX1 (thanks Luca!). Because of the crop factors on each camera, the BMCC gets the close-up shot, while the NX1 captures the wider medium frame shot. The NX1 produced a better image with minimal fuss on this one. I didn't do a lot of grading on the interview footage. On the NX1 I pulled back the saturation about 20% and applied a finishing lut. On the BMCC I adjusted Lift + Gain, saturation, sharpened and applied the same finishing lut. I do like using my favorite lens on both cameras simultaneously. I will have more footage like this in the future. Cheers

Sure @Kisaha, here are the exact commands I used below in red. Step 1: Analyze a similar good video file - Find a good video file for reference with the same resolution, frames per second, etc. When you analyze a file, the recover application will give you exact instructions on how to enter the next two commands (see image example below). My example command: recover_mp4_x64.exe SAM_0803.MP4 --analyze Step 2: Recover the streams from the bad video file - Enter the next command exactly as you see it in the results from the Analyze command... substituting the bad file in the recover command. This will extract the video and audio into two different stream files. result.xxx My example command: recover_mp4_x64.exe SAM_0804.MP4 result.hevc result.aac --drim5 --end 0 Step 3: Make a new video file using the two streams you extracted - Here you need to use 3rd party software to put the video and audio streams back into a regular video file. I think the most popular tool for this is FFmpeg, but there are many others. For Samsung cameras with H.265, I found out the hard way you need a version of FFmpeg that can handle that. The one I used successfully can be downloaded here: https://ffmpeg.zeranoe.com/builds/ Again, enter the FFmpeg command exactly as you saw it when you did your first Analyze command. My example command: ffmpeg.exe -r 24.000 -i result.hevc -i result.aac -bsf:a aac_adtstoasc -c:a copy result.mp4 --- Restated from above, here is a link to the great RECOVER TOOL from Dmitry Vasilyev: http://slydiman.me/eng/mmedia/recover_mp4.htm NOTE: For those that suck at that command prompt like I do, be sure to copy the recover application files and ffmpeg.exe file into the directory where you will be working.

Ok, here's the final result. Using Dmitry Vasilyev's recover tool I was able to recover 42% of the bad video file... roughly 10 mins of a giant 30GB 4K file. At that point NX500 stopped recording good video frames. I'm happy with that... and now knowing how to salvage corrupt video files is awesome. As I encounter other bad video files, I'll write about that here in the future. If I have time in the future, I'll make a video tutorial walking people through the process. Remembering how to use a command prompt from my MS DOS days was the most challenging part. PS: That's Sang Lee from the Carry Trainer YouTube Channel. He's our regular Co-Host and Tactical Ninja.

Hold on, it looks like I have been using the wrong settings. For the good file, I accidentally analyzed a 1080p 60fps file. These settings don't work when your trying to recover a 4K 24fps video file... duh! The Developer, Dmitry Vasilyev pointed it out to me and sent a good frame from my bad video file.

Holy Cow, I got it! I just need to use a better build of FFmpeg that supports HEVC/H265. Since I use windows, I got the download here(https://ffmpeg.zeranoe.com/builds/). This works fine for putting streams back together with recover_mp4. I encoded two videos. First a good clip as a test. That came together with no issues. Then I encoded what I was able to pull out from the bad video file (roughly 50%, before recover_mp4 crashed). The 10 minutes of streaming video came together fine... unfortunately the image was thoroughly corrupted from start to finish there. At least now I know how to check bad video files and know for sure... and I didn't loose any critical footage there. I'll think of this as a good training exercise!

I just tested one of my good video files. Pulling the streams through the Recover_MP4 program went smooth... however I still wasn't able to put the good streams back together with FFMPeg. Got "result.hevc: Unknown file format" again, so FFMPeg looks like the main problem for me too. On the bright side, that means I may still recover half of my damaged video file if I can put the streams back together somehow...

I found his email on the recover_mp4 tool and just sent him an email with a screen shot of the crash and a dropbox link to my bad video file. I agree, who ever this guy is, he's my hero. As soon as I successfully rescue a video file, I'll start sending donations his way.

--- Hmm... I maybe stuck with this one. FFMPeg is giving me "Unkown file format" for my result.hevc file.

Thanks Kisaha, I am trying the tool you linked above and it seems to be working. I've got a 30GB file from my NX500 I'm running recover on now... I'm not sure if it's normal, but my stream recover operation is slowing way down at the 41.331% mark. I'll let it run over-night if I need to. I'll let you know how things go when I get to step #3 with ffmpeg. I was hoping I might be able to load the stream files directly into Sony Vegas or After Effects to trans-code. I've played AAC audio files on my own before... ------------------------- Whoops... My recover just crashed. I'll pass this along to the developer. Hopefully, I can use the half of the stream it successfully pulled out.

Part of life using hacked cameras is dealing with bad or corrupted video files every-once and a while. I remember fixing some on my GH2 years ago. Anyway, I just got back from a trip and have a couple files that won't open or transcode. Can anyone recommend a good video file recovery tool that works for the Samsung NX1 and NX500? It doesn't have to be free... Yesterday I bought the Video Repair Tool from Stellar Data Recovery after the Demo seemed to work on my troubled file. After purchasing a software license, I quickly learned it didn't fix anything at all... and after a few emails to customer support, that company seems like a bunch of Con-Artists pushing fake repair software. Doubtful I'll ever get a refund from them and am pretty angry about it.

Good to know. Thank you

Ok, here's one more video with remaining footage from out last shoot. This was done completely on a tripod with my duel camera BMCC and NX1 rig... same setup as the interview footage from the last video. NX1 is the wide shot. I didn't do a great job with lighting on this one. If I could have done it over again, I would have thrown my Diva Ring Light on around my cameras for a little more fill. The setup with him facing the sink was awkward.
