thanks! That worked! I can now play my h.265 footage, color cast and all!

edit: Also appears to be an issue with the free version only. I do not believe it appears in 15 studio on windows 10.

@mnewxcv Ah, I see, I misunderstood.

So on this Windows 10 laptop there is a program called "HEVC Video Extensions from Device Manufacturer" in the Apps & features list, published by Microsoft. Seems like the one we're looking for, perhaps?

It looks like that's exactly what I need. Let me install it and get back to you! Surprised I haven't heard it mentioned here before.

@mnewxcv Unfortunately I'll be away from my desktop for a few more weeks so I can't check until then. How would one go about checking which codecs are installed? I've never gone and installed a codec pack or anything, so I assume I've just got whatever generic ones Windows comes with.

Although, I'm fairly certain Resolve Studio has native H.265 support, which makes me believe it should come with its own codecs.

it's moreso the fact that you installed resolve 15 free on a friends computer and were able to import h.265 files and see color bleeding. I have a clean install, 2 computers, windows 10 on both, premiere pro with hevc codecs on both, and resolve shows my h.265 files as media offline. Would love for it to work so I can grade without having to convert.

It was Studio and I was running Windows 8.1. (Afaik there was no native support for H.265 in Resolve 14 Free.)

could you please tell me what codecs you have installed? I am on a clean windows 10 install, and premiere installs an HEVC codec so that I can see my footage there, but resolve shows all my h.265 footage as 'media offline', and when playing back there is audio and no video. I assume you must have something that I do not.

could it be that windows 10 uses a different h.265 codec?

damn, i got 14 with color shift, on win10

free or studio?

I got the color shift in 15, but I did NOT get the color shift in 14 (though, as detailed before, this was on two separate computers, etc.)

Perhaps the color shift only occurs on Windows 10? Can anyone offer any insight?

was your version of 14, the one on windows 8, free or studio?

Huh, that's odd. What operating system?

On a related note, my NX1 files are ALSO glitching out in Premiere on this laptop; there's this weird wavy noise pattern on top of the image. Again, these same files work perfectly in both Premiere and Resolve on my desktop. So maybe Windows 10 is to blame? Or maybe it's a hardware issue related to GPU acceleration?

I'm on windows 10, but no issues in premiere..... are you able to post a picture of the noise pattern? Is it during playback only?

It appears to be supported in Resolve 15 free, running on Windows 10. I know H.265 did not work in Resolve 14 free--in fact, H.265 support was the sole reason I bought studio in the first place!

 

Edit: For clarification... when I first read this topic, I assumed everyone was running 14 Studio. Yesterday when I tried in 15 free, I noticed the issue, so I wondered if perhaps everyone here was using the 15 beta.

I will have to take a look. I have resolve 15 and I believe all my clips load in as audio only. I just thought it wasn't supported.

@Allen Smith @SGPhotography

 Do you all have Resolve free or studio? What version of Windows?

I normally run Resolve Studio on my desktop, where I have no issues with native NX1 files. I've been using it with v14 and up to beta 7 of v15. My desktop runs Windows 8.1.

However, today I used Resolve free (v15) on a friend's laptop running Windows 10 and I saw the color bleeding. I wonder if the problem is exclusive to the free version? Or whether it's only with Windows 10?

how did you get footage into resolve free? The free version of resolve for windows lacks HEVC h.265 support last I checked. 

it looks like you are in the advanced engineering menu. How did you get there exactly? I'm very curious. 

Side note: if you put a nx_dev.adj file and follow the sequence in the thread you linked, you will get the menu shown on the first page of that thread (I've done it several times on nx1 and nx500). 

What you are showing on your camera appears to be the even further engineering settings used for adjusting the camera in conjunction with Samsung owned software in their repair facility. 

Again, please let me know the steps you took to get there. 

anyone try cineform?

would there be any advantage to not using e shutter? Why have a shutter at all if e shutter is better?

rgb boost: 1.99

exp comp: -1.6

black level: +15

others auto...

Cool, looks like the exp at - 1.6 is really dead on for the boost settings. 

nice video, I like the edit. RGB at 1.99 for all 3? What was your exposure compensation?

thanks for the responses! We ended up going with these:

https://www.bhphotovideo.com/c/product/1331757-REG/saramonic_rx9_tx9_tx9_uhf_wireless_lavalier_microphone.html

Basically a knock off of the sony. We used them yesterday and they worked well. I'm sure you get what you pay for, but as long as the wireless components hold up, I will swap the lavs themselves with a higher quality version.

As for recorders, thanks for the suggestion but I think we are looking for something more like zooms handy line. Any thoughts on h6n?

What we really need though is a cheap LED light kit. I see apurture has the new F7 out. Would a few of those be suitable for interviews using a bounce or diffusion?

does no one here record audio with their videos?! ?

Also, looking for a suggestion for a good LED light [kit]. 

Did you come up with a solution? Sounds fun

Hey guys, my crew and I are trying to step up the quality of our content and first priority is audio. We will be doing interviews and would like a high quality yet affordable wireless lav mic. If there are 2 or 4 packs, even better. Not opposed to wired lavs and wireless mic transmitters if that is the better solution. Also looking for feedback from anyone who has done interviews. Lastly, I will need an audio recorder that can take the wireless receivers, ideally 2 or 4 receivers at once and battery operated. Let me know what you guys think. 

On the camera side, I have my nx1, nx500, and a7sii at my disposal. I guess I should try to get a quality boom as well. Suggestions?

Just finished project filmed with this trick. Now Im comfortable with some contrast shots. Thus, it is definitely works in a real live shooting..

link doesnt work for me. Also, how did you use the trick? What settings did you use?

I would be worried about the video quality. At what bit rate does this save, and what type of processing does it do to the video stream? aka, compression.

I mean the RGB boost improved dynamic range in Gamma DR in my test.

Yeah, I totally get why you closed the aperture. I was surprised that closing the aperture  changed the dynamic range. I'd just never really considered it before, but it seems plausible that using different apertures could in fact affect the dynamic range of the scene that is captured.

Let me try to be clear. By using rgb boost in gamma Dr, I did not achieve more stops of dynamic range. However, it appeared that I gained a stop in the highlights, and therefore I conclude that the "range" of stops shifted one stop from the shadows to the highlights, so the number of stops was the same, though the range was not the exactly the same range. Hope that makes sense. 

And the only reason I needed to change aperture was because my scene was exposed so high. This coupled with the rgb boost made the scene overexposed at all levels. For instance, I had a middle ground exposure, and 7 stops up and 7 stops down for testing, a range of 15 stops including the middle. But with the rgb boost, I was getting full over exposure 4 stops up, and each of the stops under middle were fine, resulting in 11 stops right? 9-11 depending how you measure. But by closing aperture slightly and make the scene darker for the test, I was able to get an extra stop or 2 above mid point, and reach true black below, resulting in 10—12, like gamma Dr. 

So back to the rgb boost within gamma Dr profile, you did in fact gain a stop in the highlights, as you showed, but you still had the same number of stops, indicating you lost one from the shadows. That being said, 0-100 ire was still achievable so maybe there is a use for both settings in different circumstances depending on scene lighting.

So changing the aperture change the dynamic range? That sounds more like a property of the lens than the RGB boost.

That's really interesting, because in my test it seemed to help quite a bit. Perhaps it is dependent on what ISO you are at? Which would not surprise me. I may try to do more of my own tests later today.

0. I did extensive tests when I got my NX1 and found no difference between any of the MB settings regarding what info is captured. In other words, if you shoot with the MB at 0 and adjust curves in post, you will end up with the same image as you would by shooting at a higher MB. I concluded that adjusting MB is only useful if you will not be color correcting.

I think the MB level simply raises the black level from IRE 0 to IRE x with a hard clipping at x, the inverse of lowering the RGB boost.

What do you mean it helped you quite a bit? What helped? 

And as for what I was saying, I needed to change aperture to gain that dynamic range because even with shutter speed at max and iso at min, it still wasn't getting ire to 0 without closing the aperture. So I needed to essentially move the range down one exposure.

What ISO was that? I wathced in 2K, there is a lot of noise in the image, the darks are very dark (my monitor is supposedly color corrected). I usually have contrast in -4, to be compatible with FilmConvert color profiles too. 

Your DIS occasionally plays some tricks on you also! Amazing place, you are very lucky living there (or near there!).

I usually have Master Black at 5, but I would lie if I said I have seen big differences between different settings. What Master Black anyone use?

can you remind me what master black level does exactly?

just did some follow ups. 

PW on, RGB 1.00, contrast -5. 9-11 stops, 0-100 IRE, just like with picture wizard off. 

PW on RGB 1.99 contrast -5, aperture closed 3 stops from previous tests: 10-12 stops of dynamic range, 0-100 IRE. It did indeed have another stop in it by closing the aperture. 

Gamma DR with RGB 1.99 with aperture closed 3 stops: 10-12 stops of dynamic range, 0-100 IRE. No difference in DR when compared to default Gamma DR settings, though the stop may have moved from the shadows to the highlights. 

PW on RGB at 0.50, contrast -5, using extra lighting. 9-11 stops, 0-92 IRE. There were indeed extra stops lying in the shadows from the previous test 4, though they require a LOT of light to be discerned. Still, highlights above 90 are clipped. 

PW on RGB at 0.05, contrast -5, using extra lighting. 7-9 stops, 0-38 IRE. Again, there were stops in the shadows, but this footage is essentially unusable since anything over 38 IRE is clipped. 

These were all done just with a grey card and adjusting exposure. Strictly testing dynamic range. I cannot speak to the quality of the image since it was just a grey card and I was looking at luminance only. I don't know if you set RGB low and under expose the shot if you can bring the entire image up in post and have usable footage. It may be possible if you drop contrast low enough, but if you peak at 38 IRE, that means all the info needs to be between 0 and 38, therefore my low contrast comment. Let me know if there is anything else I can test. It seems if you are shooting for highlights, the boost is useful in not overexposing, but gamma DR default has the same dynamic range.

Nice! In 4, I'm not sure I understand what you mean by "the stop following then boosts IRE about 1." Does it not hit a wall then? My (possibly incorrect) interpretation is that you are seeing some slight increases on the waveform, but not enough to really classify them as more stops of DR. If that is the case, do you think perhaps that it's the H265 compression algorithm making tiny adjustments that push a few pixels beyond 90 IRE wall?

I do think that it would be helpful to compare tests 3-5 with a test that has PW on, but keeps the RGB boost at 1.0. That way we can isolate what the RGB boost is doing.

Also, which Picture Wizard setting are you using?

will test soon. PW tests were with PW custom. It hits a wall at 90 and detail is lost (waveform narrows), but that wall goes up 1-2 IRE in the 2nd and 3rd stops higher. 

I will get some baseline tests with PW on with rgb at 1.00, as well as in gamma DR with rgb at 1.99 when I do my tests again.
