Wide Angle - Xiaomi Redmi Note 7 Questions & Answers

Is it possible to record a video using a wider angle like the one used for photos? Videos are always zoomed in on the stock camera app or Gcam. Although Short videos have a slight wider angle it only allows 15 second videos. Is there any away to change that?

I disabled but it didn't work

Maybe you can try this version:
MGC_6.2.024_RN7_V1c.apk
I'm using it and it works perfectlt for wide angle video. Even without disabling Video stabilization.
Enjoy!
*try to search in google for the apk

I've tried that version but found no sucess with it. Here are some screenshots https://drive.google.com/folderview?id=12GGWGn79PXOYItFPlVGv8kYehRRIU7QV

So GCam is great at everything photo-related on this phone, but its video output is not impressive except for the 4K option.
You should stick with the stock camera for video recording as it does a great job using EIS.
If you want a wider view, disable stabilization in the stock camera or record at 60 fps.
If you want the widest possible field of view, use Open Camera, disable stabilization, and set the video resolution to a 4:3 ratio. That will use the image from the entire sensor

Thanks for the help! One strange thing is that on Open Camera setting a video resolution to a 4:3 ratio (video stabilization disabled) allows a wider view. On the stock camera even when disabling image stabilization/1080p60 it won't use a wider angle, unless you compare to 1080p30, which has a closer angle than 1080p60. Any ideas what could it be? There's no option on Video Settings on the Stock Camera to set a 4:3 ratio.

That's fully expected as the digital video recording standard nowadays is to record in 16:9 widescreen. I haven't seen any newer phone whose stock camera app offers anything but widescreen resolutions. Some will have the option to record in the screen's resolution and/or ratio.
So, when you're talking 1080p, it is understood that it's 1920x1080, which is a 16:9 ratio.
The sensor produces a 4:3 image, but in video mode the image is by default cropped to 16:9 – the top and bottom of the image are cut off, making the vertical field of view narrower. You have to use a third-party app to enable the sensor's ability to record 4:3 video since this is non-standard. But for typical purposes, I don't know why you would do that, although you can, if you need your camera to capture as much of the environment as possible All our screens are (ultra) widescreen though, and it's more comfortable seeing widescreen video on them.
Electronic image stabilization further messes with the field of view. It 'reserves' a margin on all four sides of the image and uses gyroscope data to move the image back and forth within the frame, compensating for the movement of your hand, and giving the appearance of a more steadily held camera than it actually was. Further software trickery may be/is involved. The final result is that of a 'zoomed in' image. That's also the impression that you might get from the difference between a 4:3 and a 16:9 cropped image from the same sensor.

Which photo size should i use in the camera app?

What should i set the photo size in the camera app? I was using the 13mp setting but the aspect ratio was small with black bars.
9.6mp is better as i can shoot photos in full screen. Am i losing any quality if i continue using the 9.6mp instead of 13mp?
The only thing you lose is a bit of zoomability. Nothing else.

Yes you are but if you don't intend on printing images in 4:3 format (standard) then don't worry about it.
Most people now days just 'view' their images on a screen or their own device. So in that case 16:9, wide screen (9.6mp) is the better choice.
FYI; I use 16:9

Personal preferences I guess. I am using 13mp
I did a couple of sample shots before. If you're not zooming in, you won't be able to tell. I do a lot of zooming on my pictures though, at maximum zoom, there is significant difference between the two. So I'm keeping it at 13 mp.

[Q] Lossless video zoom

Hello, I was reading a Galaxy Note 4 review and came across 2x lossless zooming for 30fps 1080p video recording and wondered why we don't have it.
Lossless zooming is great as it preserves detail in zoomed situations while keeping the file size big, unlike 4k recording which would consume lots of storage to record then zoom afterwards
As our phone supports 4k recording, doesn't the G2 have the ability to have lossless zooming capability?
If so, can someone tell me if there is there an app that enables us to do this, or someone, perhaps xdabbeb, can enable it for us??
Thanks

Lossless zoom is achieved when u have an optical lens movment.
I dont believe any of these phones have optical zoom.
You can't "enable" optical zoom. It literally means that the lesnses need to move back and forth. Like in cameras. You see the lens moving and adjusting to the zoom.

I thought it was a software thing on mobile phones where they increased video resolution and cropped it to show the area you are zooming in on so that the zoomed part remains 1080p??
For example, a quarter of a 4k video would be a 'zoomed in' 1080p one

I guess.. It can't preserve detail so it has to be cropped.
It's like zooming into a picture in photoshop.
We have digital zoom only. Digital zoom scales an area up to "zoom" in. It blows up pictures making them look nasty.
This is a great question and I think the prior replies have missed the concept. Yes, our camera is like 8 or 12 megapixels, but 1080p HD video is like only 2 megapixels. So when we record video on our 8 megapixel sensors, the sensor "line-skips" to resolve only a 2 megapixel (1080p) image. When we zoom in, digitally, it keeps the same "line-skipping" design as non-zoomed. This results in a lower-than-HD resolution. It would be VERY SMART to adjust the line-skipping design, or not line-skip at all, on a digital zoom, thus still using 2 megapixels worth of photo sites to capture the "zoomed" image. This is the same concept as "sensor windowing" used on RED cameras when changing the resolution. I'm surprised this is not the new/standard way to implement digital zooming on ALL modern smartphones to preserve details and resolution when digitally zooming, because of course there is no optical zoom option.

I am quite sure the note 4 does not have optical zooming. This is the reason it made me think and 'come up' with this idea.

I do not know much of cameras so I do not fully understand what you(Jackdup) are saying, but I think you know what I mean
Just wondering, do you know of any apps that can do this, or know how this works? Maybe you can explain it to a developer to implement it in our devices
Thanks

Software Stabilization for Video ??

I know there is no optical image stabilization but what software stabilization ? Its more handy for video than stills for my use.
It is using optic-flow-based image stabilization
That is about all I know.
I don't understand the hype with optical image stabilization. The Note 5 has it, and it's so bad that it makes video recording almost unusable. Basically it creates this really nasty motion-rocking effect that distorts the video, ruining the shot.
Optical image stabilization should stay in DSLRs where the lens is decently sized.
I really hope the Nexus 6P does not include it, or if they do make a toggle to turn it off for video.

I think it's been shown that it helps with night shots. Less blurriness.

4K - UHD - Stock Camera Cropping

Just made an interesting discovery regarding the Mi Max stock camera and 4K. I was running some tests on the stock camera vs 3rd party to check output quality, HDR speed, etc. when I noticed the stock MIUI camera app severely crops the sensor area when shooting 4K(UHD). I often use Cinema FV5 to get little more control over video when shooting on Android and found that although the MIUI camera app crops the sensor when switching to 4K vs 1080p, CFV5 does not. Nor does the Google camera app when set to 4K, you still get the same wide FOV as 1080p.
I haven't seen anything written about this so far so just wanted to flag this up as a decent workaround.
(see the attached screenshots, sorry about the clutter, shot in the studio )

Camera Resolution

Been playing around with camera resolution and I understand that while the actual sensor is 48MP OP defaults it to 12MP to "capture" more details (I think thing the 48MP setting provides better shots but that's subjective).
Now the question/issue that I have is when looking in Google Photos (gallery) the shots are being reported at various resolutions... most of the time not close to the 12MP that the sensor is supposed to capture the image at.
Regular lense, showing as 7.2MP --- 4000x1800 resolution (setting in Camera app is 12MP - 6.59mm)
Wide lense, showing 7.2MP --- 4000x1800 resolution (setting in Camera app is 12MP - 3.05mm)
Tele lense, showing 4.8MP --- 3264x1472 resolution (6.95mm)
Bokeh shots appear to be showing higher res, like 13MP.
Pictures taken from my old Pixel 2XL show consistently 12.2MP which I believe is the sensor size so I'm trying to figure out what setting may be affecting the resolution. File size are significantly smaller on the 7.2MP shots so I'm sure I'm losing some quality here.
Switch to 4:3.
You are shooting in 20:9 hence the lower resolution.
Perfect ty. I did select full looks like. Went back to 4:3 and seems to show the correct mp.

is there a way to fix it to provide 16:9?
