Hi guys , for some time I have noticed that the videos I recorded in full hf look sharper than I record 4K ... I can not find explanation. if it was not for unlocking the bootloader , but I have the DRM installed Tobias ... I wonder if you have not restored the quality of the camera with DRM emulated or if someone else feels the same as I am without unlocked bootloader. A greeting from Spain
I haven't unlocked my BL, so can't comment on that side of things, however logic would dictate that losing the TA partition and DRM keys would affect BOTH 1080p and UHD video processing - happy to be proven wrong on that front.
As far as the quality of the video between 1080p30 and UHD goes, I personally find that full HD (30fps) records much smoother video (regardless of SteadyShot etc) but that UHD tends to record a sharper video.
IMHO I would rather record at 1080p at 60fps instead of 4K, but that's just me.

Recorded a few videos over the past week, and I don't have perfectly stabilized hands, causing the videos to appear extremely shaky.
Just wondering whether there's any apps that provide any form of effective video stabilization.
I think Camera FX has it ?
Hi. I've tried the slow motion feature on my note 2 today and I realise that the 480p of stop motion dont have the quality and the definition of a normal 480p. I've seen another movies of other users loving the feature quality and I am a little bit disapointed. I'm I the only one?
I know that is a new feature and it's better than nothing, but...
I will post two videos to compare soon.
Sorry for my bad english.
Thats due to how slow motion recording works.
If you record a ×2 slow motion video for 1 min it will result in a 2 minute video.
In order to maintain the same fps as a normal video, the camera has to capture and process ×2 the frames in the same 1 min of recording.
To facilitate the increased workload, the camera captures lower resolution frames.
You will notice that x8 has lower resolution than x4 etc.
Sent from my GT-N7100
I also think that is because the interpolation algorithm (?) that is being used to create the extra frames. (I don't think the camera actually CAPTURES each frame). I'm still doing some tests to determine which would be the exact speed/frame counting on the camera.
Here is a video of my dog jumping. You can still see the blurriness in most of the shots.

I tried screenshots in Album; Video; & MX Player Pro using different codecs & 4K videos and all, but all came out in 1080p.
Not sure if it was supposed to be in 4K though.
So, how can we be sure that 4K content is being correctly?
Thanks.
The screen is 1080p by default, so if you take a screenshot, it will be a 1080p image displayed.
If there are sufficent pixels to push either in image or video format however, the device will push them up to 4K.
For example, if you find an image or video with at least 3840 × 2160 pixels, it will be shown in that resolution. View them via the Album, or Video apps (I'm not sure about third party apps).
If you do a Google image search for 4K wallpapers, you can try...
Thanks @nobnut,
But I have tried a lot of 4K content yet, even photos viewed in the album should be displayed in 4K if I'm not mistaken.
It's just I'm not sure whether the 4K kicked in or not, and would like to be sure somehow; can't rely on eyes alone.
I tested screenshots in Album, Video displaying 4K content, they all end up in 1080p.

Android 5.1 Lollipop DOES NOT support 4K natively. The system can't therefore produce 4K screenshots, and thus 1080p. The reason why it's not 2k res on the screenshots like Galaxy Note 5 is because Sony chose that the system should run on 1080p and not 2K.

Doh!
That's the problem. You are taking a screenshot in 4K mode... the screenshot is not taken in 4K resolution however, it is a 1080 screenshot, so it will obviously show as 1080.
You just have to take it on trust that 4K content is screened in 4K. You convert it back to 1080 when you take a screenshot of it though
@KbaB.BroS Thanks, I was reading about that limitation yesterday. Guess I'll need to wait for Android M! @nobnut I'm specially concerned about custom roms breaking the 4K functionality! Can't really trust 'em!
P.S.
I'm running RomAur btw, it's superb, except for some random reboots.
There's a kernel which restores DRM-tied functions as well, for unlocked bootloaders.
Your eyes may not be able to tell the difference. Basically, in album app, when you open an image, it'll be 1080p and after about 1-3 seconds, it'll crossfade into 4K. It's easier to spot with small text and on eyes.

@CLShortFuse There is no 'crossfade' with Image Enhancements off, at least on my end. Can't be sure if it's because of the switch.

Yeah, I don't know what to tell you. With or without X-Reality, you should see a change. Take a look at the sample photos by Yu Takae. The text on the bottom right should look clearer after a few seconds when 4K kicks in. When you swipe to change picture, it renders are 1080p. After a few seconds you should see things clearer.

I don't think the difference is FHD -> 4K transition, because you can clearly see the text even on a standard 1080p screen. I think the phone loads a light preview (the one used in the gallery?) and after that it loads the full image. It can be for being fast when you scroll pics. I made some tests with my old Z3 and default pictures of the Z5p.
And, btw, if you swipe between pictures it always reload like that. But if I'm in gallery it should be 4K always, no need to change the res.
Not as clear as when it switches to 4K. You don't need a second phone to test, just use another image app like Google Photos.
Take a look at this:

The way you know if 4k videos are working is to press play on the 4k video then 'pinch zoom' once and you'll see the quality (you can do this with any videos anyways)
Also the 4k logo in album in the bottom corner means the video is 4k. And the battery will drain more playing a 4k video then a normal 360p 540p 720p and 1080p video (because 4k bit rate is higher - hence more processing)

But even in Lollipop is possible to watch videos in 4K?
Hi people,
I recently found out, that I can only record video with very low frames per second.
30 to be exact. The Mi5s is capable of 60fps in FullHD, or 120p in 720p I think.
My next question would be if somebody does know of a working mod to boost fullhd recording to 120fps as there is a mod for the galaxys8 for example to do exactly that (or even 4k with 60fps).
Thanks everyone
So GCam is definitely the answer for getting the best photo quality out of this phone in almost any situation, but let's see how we can record the best possible video.
Btw, when you first try video recording with the Note 7 in low light, it's natural to be disappointed since you're comparing it to GCam's photo output in low light. GCam uses frame stacking and other techniques to remove noise, increase dynamic range and get details in both shadows and highlights as well as the rest of the image. To produce only one 12-megapixel frame, it uses anywhere from 3 to 15 frames and takes a few seconds to do the complex blending and computations to create a great low light photo. Without a much stronger SoC, ISP, a better sensor and more advanced processing algorithms, this is impossible to do while recording a video, as the phone is struggling to keep up with recording 30 8-megapixel frames (UHD) each second or 2-megapixel frames in case of 1080p. They've barely managed to get SD 660 to comfortably use real-time EIS at 1080p30, along with auto focusing, WB, exposure, noise reduction etc.
So, knowing that in low light this phone's video recording will never be great, let's focus on other aspects of its video recording. My only idea for improving low light video recording is to find an app that can use a high bitrate in order to avoid introducing additional noise and artifacts. This also applies to filming in daylight.
I'll start with some findings about the differences between the stock app, GCam and Open Camera when recording video.
STABILIZATION
As far as video stabilization goes, only stock camera's 1080p30 EIS properly uses gyro-EIS and that really is the most beautiful stabilization you'll get out of this phone. No wobbling or image distortion, it just softens the shakiness, as if the phone were on a gimbal.
1080p30 EIS in GCam – it's instantly noticeable that the viewfinder here is stabilized (whereas in the stock app it isn't). It appears to be using the gyroscope, but not in the same way the stock app does. Stabilization is OK, but not as smooth as in the stock app and wobbliness can be noticed occasionally, with more abrupt movement.
UHD EIS in GCam – better than no stabilization, but wobbliness on the edges tends to be obvious when there's a lot of movement.
1080p30 or UHD EIS in Open Camera – also a stabilized viewfinder, but the stabilization algorithm here is very wobbly, which is extremely noticeable in UHD, so try to hold the phone as stable as possible when recording in Open Camera. The highlight of Open Camera for the Note 7 is its front-facing camera UHD stabilized video recording. So far this is my only use case for Open Camera on this phone (plus testing).
If you like using 1080p60 because of its smoother panning and movement in general, here's a tip to stabilize 60 fps videos: shoot in 1080p60 without EIS in the stock app or another app (using a high bitrate when possible) and then stabilize the footage in Google Photos, which does a nice job unless the video is impossibly shaky.
SLOW MOTION
In my testing, I've never managed to get a smooth slo-mo video out of the stock app and I've tried it after every MIUI update so far. At 1080p or 720p, the result is always a stuttering slo-mo video. GCam to the rescue!
GCam can record stutter-free 1080p slo-mo for a long time (I tried it for a couple minutes) and the resulting video is smooth as butter, suffering only from an occasional hiccup here and there. Perfectly usable.
Open Camera can also record in 1080p120. Different apps should be tried out to see how smooth the slo-mo is and which one is able to use the highest bitrate, leading to the highest image quality. Although image quality does appear to be limited in slow motion mode.
FIELD OF VIEW (FOV)
If you have your phone on a tripod or you can lean on a surface to stabilize it, you should turn EIS off. This will give you a wider field of view and a sharper image. When you're recording a video, the top and bottom portions of the image are cut off to accommodate for the widescreen format. This already makes you lose around 25% of the image information that the sensor can actually see. EIS works by further zooming into the centre of the sensor (or cropping the image) and using the now-extra information to shift the frame in any direction as necessary, to produce an impression of a more stable footage.
The phone will not recognize that it's on a tripod and turn EIS off. You have to do that manually. Why would you want to do that? If you want:
1) to capture more of the scene (a wider field of view), with EIS on, you'll have to step back (which is sometimes not possible)
2) better image: stabilization comes with trade-offs. If you don't need it, turn it off. The phone will be able to use a greater number of pixels to create your fixed-resolution video, resulting in a better image.
With 1080p30 EIS off or UHD without EIS, you'll have the widest FOV possible for video on this sensor. Only top and bottom are cut off for widescreen.
1080p60 EIS off – for some reason, this has just slightly narrower FOV than 1080p30 without EIS. The same FOV appears to be present in 1080p120 (slow motion).
When EIS is on, it crops the least on the stock app, slightly more on GCam and the most on Open Camera.
VIDEO AND AUDIO BITRATES AND QUALITY
Work in progress. So far I can only tell that stock and BSG's GCam produce different videos. Stock uses a higher video bitrate and GCam a higher audio bitrate. Open Camera tends to put on a yellow cast, presumably to make the image warmer. Also, bulkin's GCam allows you to select video bitrate. Haven't played with that or the bitrate in Open Camera.
It's also worth to test other apps, such as Cinema FV-5. I've had luck with that on previous phones.
My recommendation is Open Camera by mark harman
Plzz any one provide me the link

Very detailed observation.. Thanks for sharing. ?
Have anyone tried 'Footej Camera'?
Great post. My recomendation for all uses is gcam, not the best in all but not the worst. Perfect for a daily use
There is a possibility to set the video bit rate in some of the other GCam MODs.
I can recommend this GCam MOD made from developer marlin-ku OR this GCam MOD which have much more valuable options (speed / ISO optimisations) from developer bulkin043. The last version of the second MOD is available in the Telegram channel here.
This port is the best working - one of the few other GCam MODs I'm frequently using on my Redmi Note 7.
have you tried anx camera

is it is also true for 4k30 ? do you getter final image quality and stabilization if you do eis in google photo as it must be a more complex algorithm vs "eis on" that only must use a simpler faster algorithm that runs in real time
is it hardware accelerated by the snapdragon 660's Spectra 160 ISP or is it software running on the arm cpu (question both for " eis on" and for stabilisation done in google photos app )

Google photos stabilization is good, sometimes it does a miracle, but some artifacts appear in the video. It's more aggressive and intelligent than eis on but quality could be not so good. (I don't know anything about which processor is used, but in Google photo is a lot slow the stabilization process, about the double of the video duration)
video quality difference between 4k and 1080p on bsg mod
i installed this gcam mod : https://f.celsoazevedo.com/file/cfiles/gcm1/MGC_6.2.030_RN7_V1a_FINAL.apk but i notice that 1080p and 4k have a completely different look (different WB, different DR) is it due to snapdragon 660 limitations ? is gcam only configuring the hardware capture codec for snapdragon 660 hardware or is it applying some software computation (google proprietary code) on each frame in real time ?
Best video camera app for me is open camera. I do 1080p with 120 fpS with that and it's awesome. Other one is filmic pro. I can shoot flat video and chose nitrate and frame rate.

Okay, I've than that... Thanks
My best is filmic pro. It is dedicated app for video making. U can record in flat/log profile which u then can color grade later on.
The quality is greater than other app.
Open camera is also nice but it has less control over the video. U can't control color temperature and u can't basic color grade ur videos. Plus u can't save ur preset.
I have no luck with GCam and stock one.
Pics GCam, Video Stock
Interesting Thread. On MIUI Global 10.3.6 and now MIUI Global 11.0.4 (Android 9) using GCam PMGC_7.0.009_Astrophoto_Version_V12 overall I'm impressed, activated Sabre and H265/HEVC (edit/play/upload compatibility seems good for the apps I mostly use which paired with the smaller size is good). Not sure if really but crispness/clarity seems well improved as well as less speckles/red-dots especially on the skin in artificial/low light. EIS also still very good.
I also use the stock camera and OpenCamera, so what bothered me in GCam PMGC:
a) still focus flickering in video (can it be optimized by any settings?), stock RN7 camera IMHO has considerably less such flickering?
b) needing GSF: so no CustomROMs? Or is MicroG able to solve this?
c) found no possibility to save to SD-Card DCIM, I think in PMGC V3/V4 versions this still was available?
For OpenCamera while b) und c) are no problem regarding a) there seems to be good micro movement EIS but overall movement/transition is not so smooth; focus seems manual (tapping on-screen) so I could not see flickering . I like OpenCamera for the many settings especially the filename without prefix. It is also possible to set RAW DNG or WebP (I use 4x3k JPG 84%), Exif tags, HEVC, 24 fps, flat/log profile. I wonder why half-max-res pics (2000x1500) are not available to select. For video I would like to have something 16:9 slightly bigger then FHD so like 3K (2560x1440) which is not available (only 4:3). I also can not find timelapse.
A friend has Filmic on RN7. It has pro options and as well HEVC. As i tried once EIS is ok (below stock/GCam) and it seems video focus flickering is noticable just a little more then Stock and GCAM is considerably worse. I do not like the 1/3 screen Play preview of taken videos (just 3 show up) and also the files are not saved in the standard DCIM camera folder on the SD (CMS External Storage, not found by Gallery Apps).
Currently my preference is:
Images: GCam PMGC
Video: RN7 Stock; Timelapses: GCam PMGC
Hi everyone! Back to this topic to ask you a question. After the recent upgrade to Android 10, still with MIUI 11, I've noticed that
- stock camera has video stabilization working "after save"
- gcam (tons of version tried) and opencamera have no more stabilization. Once it was directly on the screen. Now there's any noticable on the screen or offer save.
Do you have the same problem? Thanks! Any way to solve this?
