Crop the screen to 1080p for screen mirroring - Samsung Galaxy S8+ Questions & Answers

Hi, I'm using chromecast with my 1080p projector. Since S8+, all android with 16:9 aspect ratio filled the entire screen. Now because of new aspect ratio the image is cropped. But the source - presentation / photos/ videos is in 16:9, so there is black border around the image, looking pretty bad. Zoom is not solution, because it is decreasing quality. Is there option to crop the S8+ screen to 16:9 for screen mirroring? Thanks!

Widescreen Video?

Here's a question- Is it possible to take/capture videos from the camera of the HTC Topaz in widescreen formats? I'm able to take pictures in widescreen formats (By widescreen, I mean that it uses up the entire screen when it generates a preview of the picture and then saves it in dimensions that are the same proportionally ), but it'd be great to do the same with video. Any answers as to whether or not this is possible on this deivce? I've seen it done on a couple of other HTC devices, or at least attempted... Any thoughts? Thanks!
I am not sure it is possible right now.
One thing you may not be aware of is that the widescreen picture mode is faked. All the phone is doing is cropping the real 5 Megapixel 4:3 screen ratio picture into a widescreen format. It is not as bad as a digital zoom but you are still losing pixels.
Whether it's possible or not....it's pointless.
Switching the camera to "widescreen mode" just reduces the number of vertical pixels.
You might as well record with the most number of pixels and crop afterwards.

Camera zoom in when recording

Hi there,
Got the Samsung S7 and from today when trying to use the camcorder recording mode it will zoom in and not having the current view when it's on normal camera mode. Can someone help how to solve this, factory reset didn't work.
VGA and 1:1 quality works without zoom in but the HD, FHD 1920*1080 and above not.
Thanks.
My camera does the same exact thing, not sure if it's just a built in feature of the phone. Anyone else experience this?

I think it's because of the aspect ratio of the sensor (4:3).
The camera has to zoom in and crop the sensor when you choose video mode with those resolutions...

How to solve because its strange from.te beginning I had no issues and since yesterday it started, same settings.. anybody an idea if it will ve solved by samsung soon?
Nothing you can do, recording at 1080p requires only 2 mpixels, the whole sensor is 12 mpixels. If you record at 4k it'll zoom in less than at 1080p.

Just turn off video stabilisation and the zooming would be gone! Suppose you know why.

That doesn't work. and this is OIS, not EIS so it shouldn't matter.
So this is due to the camera sensor size? It's very annoying. Especially when I frame my video then start to record and then I'm zoomed in

The video stabilisation in setting is EIS. OIS is built in the hardware and can not be turn on/off. It is permanently on.
And you can't magically take a 16:9 video/image on the 4:3 sensor without cropping.
If you are annoying by zoom in effect when framing the scene, you can first change the image resolution to the one with 16:9 ratio thus already cropped viewfinder before framing the video.
The sensor in S7 is not a native 16:9 sensor like in S6, it is a 4:3 sensor so in order for you to record in 16:9 resolution video, it needs to crop the image while also giving you an impression of zooming in due cropping. The reason why VGA is fine is because its resolution ratio is already in 4:3 format, just resized down to VGA resolution. All 4:3 sensors including the one being used in DSLR are also cropping the image when video recording in 16:9 format.
So if I select 16:9 ratio for stills, will this effect video quality selected at FHD?

I know this is a dead thread by now, but this doesn't really address the issue. The GS7 does more than just crop the 4:3 into 16:9, it also crops in a large amount when selecting 1080p as opposed to downsampling the 1080p image as some other cameras do. This is quite annoying, as even if all I need is 1080p I still have to select UHD to get a wide enough FOV, wasting storage space and meaning I have to downsample it later.
Realized later that the above is only true if you have video stabilization on, disregard it, I'm not sure how to delete my reply

HTC Camera - is there 16:9 mode for photos? 4:3 only?

Image samples are always in 4:3 format.
Is it possible to change image format in camera app to capture still photos in 16:9 mode?
(Of course I know there are 3rd party camera apps etc. but nothing beats native support for 16:9)
I don't see the reason why not. Here is screenshot of my pixel camera settings. I believe both phones have same screen ration.
My HTC U Ultra has 16:9 and 4:3 modes.
16:9 is just 4:3 cropped so there is no reason why you should photograph in anything but 4:3 and then crop, to keep all the information.
Selectin 16:9 mode removes a big chunk of the information from the sensor. Sure it fills the screen, but that in itself is a poor reason.
Reason to have a 16:9 option is the same reason why most phone cameras have a auto mode. Most people just want to point and press the shutter and be done with it

Video zoomed in. Digital Image Stabilization, Aspect Ratio

Hello. Is there any camera app that would allow to force 4:3 aspect ratio in video mode without Resolution loss ? I've got xiaomi Mi Note 2, and in 16:9 mode video seems to be zoomed in. I tried almost every camera app in store. When it's in 4:3 everything is ok but resolution is ~ HD (definitely not full HD). No application could be able to force 4:3, even when there was such an option.
Everything thanks to digital image stabilization ...

Too much margins in streaming video

Some fix for the exaggerated lateral margins that it makes in the videos to the screens of YouTube, Netflix, etc.? You can zoom and fill the screen but the video in its original format, has an excessive crop.
In other Xiaomi devices this does not happen.

First of all, I am pretty sure you posted in the wrong category. This should got to Questions & Answers.
Did you ever play GameBoy Color games on the GameBoy Advance?
If yes, you noticed, that all the games had black margins, except you were resizing the image with the L/R button.
The reason for that is that what is being displayed does not match the resolution of the screen. So if your video is 480*240p then it will have margins on a Full HD or 2k display.
Same goes for any device, like your phone. Previous phones did not have margins, because they probably had a screen resolution of precisely 1920x1080p. So most videos will fit perfectly, because that is a very common resolution for videos.
Now the POCO has a higher resolution: 1080 x 2400, which is not perfectly standard. Your video is guaranteed to not have this resolution, as can be seen from the screenshot. So of course there will be black margins. The only way to "remove" the margins would be to resize your video or get an older phone with a resolution of exactly Full HD.
Conclusively, that's not an issue with your phone or whatever. It's an issue regarding different resolutions, which happens to EVERY device on earth that has a display measured in pixels.
Although they are related it's more of the aspect ratio thing than resolution. Common aspect ratio for content on platforms OP has mentioned is 16:9 where our poco has 20:9 screen. 16:9 was the most popular on mobile devices before the "bezel less" era and still is the most popular for TV.
Try to do the pinch outwards gesture to stretch the video to full screen?
Use the Video Toolbox?
