Px3 reverse camera - MTCD Android Head Units Q&A

Hello. I have px3 android 7.1.2. Dasaita brand. How are the backup camera settings done? I couldn't find it on the menu. It's not in the factory settings either. I want to set pal - ntsc. Can you give me information?

Unfortunately, there is nothing like that in the settings. The device should work with both progressive and interlaced scanning in various NTSC/PAL/SECAM color systems. Manufacturers focus mainly on NTSC when testing because it is used by Asians and Americans. They don't focus much on PAL, that's why it doesn't work in some cases. You will have to buy a new camera, just to be sure, get NTSC.

New to android.

This is (or will be come June) my first experience with an android set. Now I've read that the codec support in Sensation is quite poor but I'm wondering if that support could be extended to include e.g. .mkv playback now that Sensation will (hopefully) be unlocked.
first: welcome to the android world
second: http://forum.xda-developers.com/showthread.php?t=1097503
Thanks! So the codec support depends on the media player like in PC OSs.
I'm also wondering if there's any possible "fix" for the quality of the photos taken with Sensation's camera. The photos I've seen aren't too bad but someone mentioned too high level of compression of the file which creates artifacts. Are there apps for the camera that will lower the compression level? The ones I've looked at on Android Market don't mention anything about compression. Or maybe it's a hardware limitation.
Welcome to android as well.
To be honest I am pretty new myself. The sensation when purchased, will be my first android smartphone. Had an Archos tablet for a few weeks before lending it to my sister 6 months ago lol...
Regarding the camera, I am not certain if we are talking about the same thing but they do seem similar. In the engadget review, they mentioned 'artifacts' where isolated areas of a picture were randomly soften or blurred. This is most likely due to software/settings that are processing the raw image before saving as pictures/files. With the recent HTC bootloader unlocking announcement, we should be able to see custom ROMs or even just single solution, fixes, tweaks, updates or whatever you want to call them to address issues like this. Or of course HTC can also fix the issue themselves.
Here is a link to the review if you need it

if you are looking for the camera portion scroll down until you see the picture of the daisy? (sorry know very little about flowers)

[Q] Is our camcorder app able to record PAL instead of NTSC?

Hi there,
I am not sure if this is a HTC Sensation only question or maybe a general Android issue. I tried the search here and at Google, but it looks like nobody did ever wrote a word about this?
I am looking for a PAL compatible camcorder mod or app to be able to record PAL standard compatible. That means I want to have a camcorder mode with 25p, 50i or 50p. Not as many frames as possible. Also not NTSC with 30 or 60 frames. Just PAL with 25 or 50 frames per second, maybe interlaced.
I am using PAL video editors at hobby and at job. I do like to use my FullHD camcorder and maybe my HDV also. So my video projects are PAL, thats the video standard here in Europe. I can't ever use my phones camcorder beause all pan and zoom will look very bad if imported into a 50i project. Thats because the camcorder in our phones seem not to be able to deliver PAL? The conversion while importing into my project is from 30p or 60p down or up to 50i or 25p. That must look bad after importing.
I know that our phones original camcorder soft goes down with the frames if the light is not enough, I also know that some modded camcorder apps seem to be able to record with stable 60p at FullHD. Maybe it is possible to reduce the frames with a modificated media profile or with a camcorder app?
Does anybody know if these phone camcorders are able to record with a stable rate of 25p, 50i or50p? I would like to use this feature of my phone really much..
Thanks for your answers, hints and help!

:fingers-crossed: Yes, thanks. Also Australia uses PAL standard. Only USA and Japan have NTSC I think..
Does anybody know camcorder apps that are able to do PAL? Please?
Nobody?
Hmm, since the forum rules says that I am not allowed to post my question anywhere else than here, maybe someone out here can post my question at a camcorder app threat? Maybe the specialists there are having an answer?

Question on UHD Video Recording Limitations

Hi All from Toronto, Canada!
I hope this is the right place to ask this. My question is as follows:
I have an Honor Note 8 with the Kirin 955 and the Mali T880. The camera on this phone is the Sony IMX278 RGBW sensor, which isn't the best as I hear, but is able to record 4k/UHD video.
From what I can gather, the Kirin 955 doesn't support hardware level UHD video encoding (only DECODING), and any phone with this SoC isn't able to record 4k/UHD video.
Would it be possible (albeit a lot of work) to record 4k/UHD video and either encode it at a software level (i gather this would be really slow), or even by using the GPU instead of the CPU to encode it? From what I can gather, the GPU is much more efficient as processing graphics and 2D video shouldn't be a problem at all for it. It seems like a solution to this would allow any user with this hardware configuration to be able to enjoy their phone cameras a lot more.
I know 4k/UHD video isn't really widespread yet, but I do have the necessary components at home including a 4k TV to be able to enjoy this resolution, so I am looking for a solution to this. Is it as simple as modifying the media_profiles.xml file and installing a different camera app?
I don't know a lot about android development, but I am making it a point to learn as much as I can, and I have put quite a lot of research into this idea before posting here, including searching on XDA. I work in Software Application Support for a small CRM, and I have years of experience doing mods and customization on android devices, so I am familiar with the landscape here and I should at least be able to understand any answer no matter how technical.
Thank you for your help!

I don't know much about Kirin SOC but with say QCOM to be able to encode via software using say FFMPEG the ISP would have to return preview frame with UHD Dimensions.
Its probably Capable of Encoding 4K maybe can check if it can be modded by understanding how everything works .
1st Check in /system/vendor/lib /system/lib/ lib64 for any file containing the word camera zip them attach them to your post
2nd download freedcam from play store in the menu scroll down and save camera parameters attach the file outputted to /DCIM/FreeDCam

https://forum.xda-developers.com/xz-premium/help/how-xz-premium-vr-support-daydream-t3622696
I got help from the above article.
so I am using daydream as 4k / 2k.
1. Use adb to change the resolution to 4k / 2k.
2. Use the attached 4k / 2k qr code.
3. Enable the skip vr entry scene in Day Dream Developer option.
4. Turn off nfc.
5. Use Daydream.
Attached
Daydream qr code is the manufacturer value extracted from the Daydream View 2017 nfc information.

Beyond the sexual and monetary moralism surrounding virtual reality devices, I just want to know the truth.
I think. Xz Premium is the highest visual quality of all virtual reality devices for use with YouTube Vr Platform.
I might be telling a lie. I'm just curious.
4k ips That's great. Video quality.
(Pimax 4K is similar panel)
Low latency could be a problem.
But I had no problem viewing flat screen videos.
I liked the movie watching very much with Xzp.
One could say
the daydream view 2017 fov is narrow..
Netflix vr has a film, Pacific Rim.
Watch this movie. If you use big screen size with Daydream View 2017, you don't understand the movie action scenes. Symbol recognition fov of a human being is 60 degree.
I think..
Daydream View 2017 is great for movie watching..
There are already sufficient viewing fov to watch movies.
I think..
4k ips came close to the experience of looking at PC monitors.
I wonder if I was wrong..
I wonder if people just don't know..
--------------------
Further information...
Oreo rom is good working in 4k/2k vr.
not nougat..
In nougat..
The screen is stained.
Kernel problem?
Sadly, I have no ability.

moonlight for daydream
https://www.reddit.com/r/daydream/comments/877mcp/moonlight_for_daydream_stream_your_pc/
It is an app to stream 'PC screen Itself' with high video quality wirelessly.
'Wireless'
I think...
Netflix vr has a video quality of 500 ~ 600p
With this app,
more than 1080p netflix video contents enjoying is possible.
This app works for only nougat..
Operating in nougat..not oreo.
Sometimes the screen gets stained.
if reboot, ok..
I want to use this app and 4k/2k vr at the same time.
If so, the app should work in Oreo or there should be no spot problem in Nougat.
Can someone solve this problem?

That's great Man! Thanks for sharing! But the Title... lol
I will share it on My Patch since i just enabled Hard/Software Support for Daydream / VR with the coming Update. Hope it delivers the wished Quality and that the 4K Display switch Option on AOSP soon works again on Oreo...
For now works just the ADB Command.
BR
Edit: Would be interesting how good this works on top of My Patch on AOSP since it has full Support for Daydream and VR (Including Configs, Permissions and Settings + Play Store App Compatibility). Will release it soon and hope somone can test it with a Daydream Headset...

That sounds very interesting - I will test this in the near future.
I don't get the thread title though , but I can say the XZp has a much clearer image than my Oculus Rift or my last phone (Galaxy S6). But it is only really good for using a vr setup that doesn't require to move your head. I use VRTV as my player, not the perfect app but pretty near to perfect, if Daydream will ever work on my XZP again, I'll test DeoVR , which is in my opinion the best player for PC/Oculus and hopefully for android as well

Awesome to hear from someone who can compare the Quality! I was never a fan of this Headmoving Stuff. SONY HMD was the true sh** when it comes to a great Head Mounted Display Experience and as a Gamer to i still prefer to move the View Field with My Mouse instead of using Sensor. I can just recommend this kind of using even with VR Headsets. Less shaky and a lot more Precisely!
Another Question, Is heat a Problem on Your actual Setup? I can ensure it will be much cooler at all with AOSP and the Patch. Just played a Dungeon Session Shadowgun Ledgens on Ultra Settings with 60FPS and i got almost no heat or Performance Issues. It's incredible how big the difference to Stock is...
I'm also one of the Founders from Riftcat (VRidge), and i can really recommend it btw. I also bought Moonlight but i was never able to use it as HMD (Without Headtracking). It would be Ultra Killer to have a Way to use the XZP as a 4K Head Mounted Display with this two Services. Would be really thankfull for any Ideas (Mainly using the PC for Video and Work, just sold My GTX 1060)!
And a last Thing i have to say after reading Your reply again. The XZP doesn't supports VR with Hardware or Software (But it could) on Stock right!? The funny Thing is, i really enabled full Support for it. You can choose between Flicker Reducing or Sharpness in the Display Settings, and it allows You to setup Daydream on the normal Way. Visit the Play Store, Download the Daydream App (VR main Services are included in the Patch) and set it up. It does also support advanced Daydream Options and it handles the VR Services over advanced profiles which are involving the Hardware and the Software Parts of Android (Full Support). So it should be a huge upgrade compared to Stock. And AOSP has also Options for the Display Resolution / Frequency (Which are not working yet), which could be the perfect addition to that (Switching between Options without ADB).
I would really appreciate to hear from You what You can reach with the Patch and AOSP! Sadly do i not own a Daydream Headset (Just a Chinese Cardboard which collects Dust), or any other Kind of VR Headset so i can't fully test everything. But i think i will go to buy a Daydream 2017 Headset when i have some Money again. Would really like to use My PC on My XZP Screen...
Can't wait to know more about all this! BR :highfive:

I've always used the vrtv, my best player ^^
It plays on the Sony 4K panel without adb command.
Daydream Skybox app
can also be used with 4K panel using adb command.
I haven't used deo vr,
but I'm looking forward to a great experience.^^
I do not know about PC vr device( Samsung Odyssey was put on for a while, and tracking was great.)
but I think it is okay to flat video watching head tracking. Move less than one expected.
I think smartphone head tracking capability is poor and there may be a problem there. Instead, Xzp video quality is supplementary.
I think
not suitable heavy game.
suitable video watching like youtube vr, casual game, 2d screen game..
I look forward to your response with experience as I can not use a large number of vr equipment.
thanks your reply^^

Carbonrom + snappatch
It doesn't go over daydream vr entry screen.
I can't get to the next step on the controller setup screen.
stock rom v1848. It runs well.
I haven't checked more anything else.
Sony Oreo stock Rom are well run but the screen brightness turns dark during long time using 4K setting vr because of the heat problem.
------------
Daydream View 2017 headset is recommended. It is comfortable-fit, lightweight, and has good fov and very little misting. First of all, It has a 'heat sink'.
https://www.virtual-reality-shop.co.uk/
There is a best-seller baofeng mosing s1.
It is known as the current mobile best fov.
I bought it.
For xzp, size do not fit, so further work is required.
There is a misting. can't use glasses. I think fov is fine but that doesn't get ahead of Daydream view 2017 quality.
Fov is less interested when adjusted.
I eventually use a Daydream view 2017 headset.
Fov small, awkward sense of wearing,
but untouchable video quality is Antvr.
For image quality, sometimes I use antvr.
-----------------
That's all.
I can give you information now~
Post moved backwards.
Wow, seems that this thread is starting to skyrocket
I will take my time and read everything again, currently at work and a bit in a rush....
With my current setup ( g8141, turbo p75d rom , vrtv , bobovr z5 headset with daydream compatible controller, with sitesinvr calibration ) I have no heat issues (my galaxy s6 got so hot after just some minutes , that it would be more safe to wear aramid fibre gloves..... ) and the image is not distorted.
The manual "sharpness setting" the headset is offering seems to end right at the position the image is getting sharper for me, if the phones display is moved 1-2mm further away from the lenses, it might be even better, but not possible.
So maybe this is something that can be dealt with on the software side. (I remember the Oculus, DeoVR software offered a sharpness slider which did magic to some videos.... )
@Miustone: What I've read about your Snappatch is that you can alter the max bitrate limits etc which the snapdragon835 is able to play? Being able to play higher resolutions than regular 4K would be great as well.
Anyway I'm highly interested in testing this, even though this is completely new for me. Have never been using an aosp rom, has always been a little bit too debloated for me.

you are right.
From my experience..
In general use, there are no heat problems.
In general use Youtube vr operates at 1080p.
there are no heat problems.
but image is blurry.
In general use Youtube cardboard option, vrtv is 4k working. but youtube vr is not 4k working.
In adb, qr code setup use Youtube vr is 4k working.
Image is sharpness like youtube cardboard.
but heat problem..
In high temperature and sony stock oreo, the screen turns dark brightness automatically. but There is nothing wrong with the performance.

Hey Mate!
Just want to thank You before accepting the Donation! I promise that i do buy the latest Daydream Headset in Order to make the Patch fully supporting it! You really openend up a big World for Me!
You will get a Special Place on My Patch Threads for allowing Me to get the Hardware for My Development! Really appreciate it, and i'll let You know here with some Pics how it goes from now!
Looking forward to that! Thanks again!
BR
EDIT: Just bought one on Ebay and it will hopefully come very soon!
Think i can say a lot more about all this VR Stuff after being able to use it by myself. That will surely help a lot to bring this forward. And great side effect, i still have My Axon 7, means i can test a official supported Daydream Device too. Should be great to compare!

I saw the special place. I love it^^
Thank you very much for your courtesy to me.
I just want to share my vr experience about Xzp.
I'm looking forward to your work.
Anywhere in the world, I don't find detailed comparison between 2k oled and 4k ips smartphone vr experience.
All devices is not perfect.
there are good points and bad points
there is a good place to use.
I was curious.
Although good video performance,
xzp can not be mentioned in vr battleground.
there are any advantages to use xzp,
I would like to let it know for people.
Someone may use vr with xzp for the first time
because of this thread.
I'll leave a brief piece of information for xzp users.
It's no big deal. People who are interested and experienced may know.
However,
it is better to avoid the stress of first vr experience.
Everything from my experience.
It is subjective. This may not be the correct answer.
------------------------
1.
feel dizzy when use it for the first time.
adaptation Period 2 - 3 days.
------------------------
2.
Wear glasses for the low visibility person.
If vr has a focal adjustment function.
With focal adjustment, you can adjust the focus.
you can see well.
but tired eyes after longtime use.
because the image is so close to eyes.
with glasses,
the image is approximately 1m close to eyes.
1m is comfortable distance for eyes.
-------------------
3.
Each piece of vr headset has its own point of good focus sweet spot. In sweet spot, There's less of a color diffusion. You'll have your own way.
Tips for wearing most vr headset.
It is good to feel comfortable to adjust wearing straps so that it adheres to the forehead with small amount of load on cheekbone.
--------------------

qr code calibration.
I recommand Sitesinvr.com.
There is a famous headset qr code.
It is also possible to create a personal qr code using the sitesinvr app in play store.

Xz premium is not dream ready phone.
there is nfc bug.
When using a daydream view 2017 headset or third-party headset, Nfc error message will continue to pop up.
solution.
Feel free to apply anything according to circumstances.
1)
In daydream developer option,
enable skip vr entry scene option
and turn off nfc.
2)
use airplane mode and turn off nfc.
3)
Between the front cover and the smartphone,
attach a piece of 'foil'. No error message occurs even if nfc turn on.

There is a 'drift' issue with all smartphones, gyro sensor, compass.
Even all the vr equipment.
but, Smartphone in particular
To be honest, there is no perfect solution.
I am very sorry about this...
It could be the biggest enemy about Smartphone vr development.
edit.
but we can buy external sensor for daydream.
(now I got information..i'm searching.)
Is Daydream with external sensor called smartphone vr?
Anyway xzp is used.
edit. I don't find useful information.
this inormation is unclear.
<
Drift solution
1) Compass correction.
2) Gyro sensor calibration.
3) avoid Electromagnetic effects.
In vr use I dont't use anything but only daydream bluetooth controller.
( I don't know why. People report being affected.)
4) To find the controller location,
turn on location options.
It seems to affect controller drift or screen drift.
I'm not sure.
As for drift issues,
Google has advised to fully charge the controller.
I think there could be some kind of correction.
and someone recommand location - device only option.
>
There are no gyrosensor and compass compensation options on Xzp.
Use GPS status app.
This app has correction option.
and There is only compass correction option on the Google Map.
From experience,
it is likely to easily occur if you take off your headset countless times.
There are information about drift issues in the reddit.
Each will already have its own solution.
edit.
The 2018 April update for Pixel 2 just fixed the magnometer (drift).
It is said that someone installed it even though it is not Pixel 2.
I don't know that way.

Jiggy screen issue
<
Quoting..
Shelly tom' post in
https://www.reddit.com/r/daydream/comments/7asyyt/daydream_s8_jiggy_screen/
TL;DR - thick phone case or dirty center "nubs" in daydream view may cause that issue.
When it starts shaking and while still wearing it, try pushing on the daydream view flap and phone as if opening it. If the shaking stops the contacts are dirty.
Also, the little center nubs do three things.
they center your view.
they also resize the height from thick phone cases. This is why there are two of them.
they cause your display to jump around or "vibrate" when dirty.
Take the phone out and wipe down the nubs and the device where they meet. It should allow for a better contact and stop the shaking. If it looks clean there could be oil residue.
With curved glass phones, I've observed that thick phone cases may cause the bottom "nub" to not fully make contact on the lower part. Games with more motion from looking around causes the phone to shift slightly up thus causing poor contact on the lower "nub". The poor contact is the source of the shaking screen in this case.
>
Sometimes jiggy screen issue has come up.
so I decide to don't use cases and films on smartphones.
In my experience,
It was convenient not to use cases and films on smart phones. This is a subjective conclusion.
I use smart phone coating liquid instead.
It's a German-made nano tol pro product.
There are a lot of coating products.

8. about color and screen door effect
Daydream view 2017 is Fresnel lense.
Fresnel lense doesn't express the difference between the brightest and darkest colors very well.
Have two effects.
1. bad image quality.
2. but reduced screen door effects.
sony stock color mode
1. standard mode is suitable nomral lense(ex antvr)
2. vivid mode is suitable fresnel lense(ex daydream)
vivid mode maximizes the contrast between the brightest and darkest colors. complements the fresnel-lense defect.
edit.
https://youtu.be/IrircflFHzw
( Looking for images related to color, I linked this video.
I'm sorry if it doesn't suit your taste.^^; )
You can see it by changing the color mode settings while watching this video.
You will also notice that the screen door effect is strong on the strong primary colors.
because
In strong primary colors, the brightness contrast between brightest and darknest sub-pixel is maximized...
However,
it should be noted that this is not a regular colored video.
--------
Additional
This is my solution
from daydream view 2017 and vivid mode
If you don't like the color,
increase the color red in white balance setup.
If the screen is yellow, increase the color blue in white balance setup.
edit.

The higher the resolution, the better it is for the screen door effect. Because at lower resolutions, pixels are clustered together. Screen door effect looks bigger. High resolution is advantageous for the screen door effect.

9. heat issue
The foil method is neat, simple.
https://www.gamecrate.com/samsung-gear-vr-tips-tricks-fixes-overheating-devices/12916
Daydream view 2017 has 'heat sink'.
edit.
10.
you use 4k adb command/4k qr code..
don't enable Dashboard Option (in daydream develper option.)
It's not working. You don't move library option in Daydream Home.
disable dashboard option. It works.

I saw the special place. I love it^^
Anywhere in the world, I don't find detailed comparison between 2k oled and 4k ips smartphone vr experience.

A real in depth comparison is hard to find. I can just tell from my personal experience with Galaxy S6, Oculus Rift and now XZP.
I'm curious what can be achieved by software / settings with that 4K display the XZP has, but I'm pretty sure that it'll stil be a "high persistance" display overall and is lacking external "correction". If I remember correctly the Daydream headset has no electronics built in, so the phone is completely on it's own and will most likely start to drift away.... thats one big disadvantage to the GearVR for example. Don't know what regular "Daydream Ready" phones do in that case but I think they might have better calibrated sensors, or just have the same drifting problems.

That's great Man! Thanks for sharing! But the Title... lol
I will share it on My Patch since i just enabled Hard/Software Support for Daydream / VR with the coming Update. Hope it delivers the wished Quality and that the 4K Display switch Option on AOSP soon works again on Oreo...
For now works just the ADB Command.
BR
Edit: Would be interesting how good this works on top of My Patch on AOSP since it has full Support for Daydream and VR (Including Configs, Permissions and Settings + Play Store App Compatibility). Will release it soon and hope somone can test it with a Daydream Headset...

<how to activate chrome canary vr web browsing>
It had worked in other daydream ready phone.
But it did not work on xzp
Maybe xzp is not a daydream ready phone.
but
I noticed that it was running recently in miustone' Xperistockrom-V1848.(I do not check Sony Oreo stock rom operation)
Unfortunately, adb 4k mode does not work.
So the screen is blurry. However, video playback on the web is sharpness like YouTube cardboard(4k working).
It is quite useful..
----------------
adb 4k mode works in chrome 66 version.(not canary)
but screen is black... It's unusable
-------------------
chrome canary vr web browsing.
('Chrome 66 version' activate method is similar.)
1. Install the app : chrome canary
2. searchbar input : chrome://flags
3. Enable everything with VR, XR, or Daydream in its name.
ex)
-VR browsing native android ui
-WebXR Gamepad Support
-VR browsing web input editing
- WebVR
- WebXR Device API
- WebXR orientation sensor device
- WebVR VSync-aligned timing
- WebXR presentation render path
- VR Browsing
- Chrome VR virtual keyboard
- VR browsing experimental features
- VR browsing experimental rendering features
- VR browsing in Custom Tabs
- VR intents
- WEBVR auto presentation from intents
- Chrome icon in Daydream Home
use web broswing in daydream home .

I have listened to the message on your homepage.
I totally agree with your decision on social media homepage.
I think it's a better decision.
Thank you for all your hard work.
I have a close friend who has an iPhone 6s.
He is not usually interested in smartphone and vr.
I gave my friend youtube 4k vr experience with xzp.
He was very interested in flat screen images quality.(especially music video.)
He showed interest in your work I told him.
He said your work would be valuable.
Surface reactions of people in online are unimportant. Everyone who has experienced with xzp, it already knows it.
He who understood, he understands.
He who has ears to hear, let him hear.
All the best

Is FiLMiC Pro works on Xperia 5 II?

Hi everyone,
I'm interested in this phone, but sadly there is no available store in my country that I can test the device, online purchase only.
I've read that GCam support is broken because of Sony hardware/software settings.
So, Is FiLMiC supported? It's mostly Camera APIs and not processing much as GCam. Anyone can test with FiLMiC Pro Evaluator on the Playstore and give me a screenshot, please? I know There is Cinema Pro on Xperia but FiLMiC Pro has some solid settings like high bitrate and gimbal connect.
Thanks a lot

Much appreciate
Nice to see Sony did not mess with general Camera API.
This app does not fully reflect the performance.
On my x5ii, Android 10, Filmic pro 6.13.3
1080p 8bit HEVC/AVC just fine
res above 1080p 8bit HEVC/AVC jumped frame
res above 1080p 10bit HDR HEVC just fine
The developers promised to fix this issue in the next release.
Thank you for sending in that information! I submitted your information to our developers and just heard back from them. In order to fix the problem you were experiencing we are going to have to use a limited mode for resolutions above 1080p—this change will be made in an upcoming update to FiLMiC Pro. In case you're not aware, there are multiple image buffer options available within the Android camera framework and each of them gives access to different features but has different drawbacks. We use the advanced image buffer in order to provide the advanced features that we do, but if the advanced image buffer won't allow us to provide a stable frame rate—as you've experienced here—then we switch to using the limited buffer type instead.
This limited mode uses a different version of the video recorder, which limits what features we're able to use at those frame rate/resolution configurations.
'Limited mode' restrictions are as follows:
Aspect Ratios: ‘Crop Source to Overlay’ unavailable
Zoom: Smooth adjustment unavailable
Cinematographer Kit: Limited availability on some devices
Anamorphic Desqueeze Unavailable
So once the update is available that changes 2k+ resolution to limited mode, those functions will no longer be available at high frame rates. This is a hard decision to make as it does remove feature support, but it will enable us to provide stable high frame rates instead.
I hope that clears up what will be happening, but if you have any questions please don't hesitate to reach out!
