Can any phones record 2 video tracks from front and rear cameras simultaneously? - General Questions and Answers

I am aware that a number of phones can record video from front and rear cameras simultaneously and produce a split screened video. This webpage summarises such feature:
https://smartfilming.blog/2018/04/1...t-and-rear-cameras-simultaneously-on-android/
But I am looking for a phone that can create 2 separate video files for the front and rear cameras during simultaneous recording. I don't want a video file with a split screen view. I just want 2 clean / separate video files form the front and rear cameras. Do any phones offer such a feature?

I would guess that if you installed 2 additional third-party video recording apps on a Galaxy S9+, split the screen and ran both apps*at the same time, one to record using the front camera and the other app to record using the rear camera, it might work.

I thought about doing that. Can anyone confirm if it works on the newer phones and what the highest resolution is that it will support? I guess anything more than 1080p from 2 cameras would be too much for the phones hardware?
Also what I would really like is a way to launch such recording instantly with a 1 button press, or even remotely from something like a smartwatch. Is something like this possible?

I think that there is an app that can do this job

[Q] No continuous autofocus in camcorder mode?

Reviews of the Sensation seem to imply that there is no continuous autofocus in camcorder mode... can someone with the phone confirm that?
would be a real shame!
From this spec comparison between SE Neo and HTC Sensation, it says:
"There are some attractive features which the Neo has and the Sensation doesn’t, notably video calling, continuous autofocus, video light and smile detection, but overall we feel the HTC is better equipped with its dual LED flash, image stabilisation and higher quality video capture."
Yeah, I've read that too.. but would be good if someone with a Sensation in hand could confirm it.
Having 1080p recording without the continuous autofocus is a joke.
This video shows autofocus and zoom.

(notes say it was made with a prelim version, so final may vary)
The user guide for the sensation does mention in page 69 that after starting recording:
6. You can freely zoom in or out while recording video.
7. You can change focus to a different subject or area by just tapping it on the
Viewfinder screen.
Which implies that you can zoom while recording & that Focus does change.

Here's a posted video. Looks to me like everything is kept in focus at varying distances.

Without the phone I can't confirm, but I've seen several vids and none show signs of losing focus when the distance to objects varies.
Look at this video:

After watching this video, we can conclude that the HTC Sensation's camera does sport continuous autofocus and/or tap-to-focus.
I guess it would be a whole lot easier if someone in possession of a HTC Sensation could've posted in this thread.
It's tap to focus. You tap the object on the screen that you want to focus on and it then focuses on that object for you.
Have tested it, but haven't uploaded it.
Some of the 1080p videos that I've taken with my Sensation have involved lots of panning around and objects sometimes being a lot closer than others, and when playing the video back on my PC screen everything is always sharply in focus.
"Tap to focus" is like a manual override of autofocus. For example: If the camera has focused on somebody in the foreground, but you actually want the background to be in focus, or vice versa.
I jsut had a play around with it on my Sensation. While panning around with the viewfinder it does auto focus. While actually recording video it does not, but refocuses if you touch the screen. I'll get a video done showing it.

Youtube really kills the framerate... anywhere else I could upload that would be better? As you can see, it does not automatically refocus. When you do touch the screen it refocuses quickly though.
Edit: This should do - Dropbox link to video file

Instagram Picture/ Video Poor Rear Camera Quality

Hi guys,
I am using latest global stable rom (7.5.1) and i noticed something wrong with instagram. As you all know instagram released new update and you can use the instagram like @snapchat which you can upload your story. I liked the app. But the problem is when you upload a story you have to take a picture or record video inside of the application. When i try to do that simply the rear camera picture or video quality is amazingly poor.
Any other one faced the issue? And any solution you you can provide?
Btw I tried global developer rom latest version as well (6.7.29) which came back to same issue as well.
Waiting for your feedbacks. Thanks.
After few tries..
Well ok what i found out after few tries is quite funny and simple. The problem is not the camera drivers or device specs.
Instagram app is automatically selecting the lowest quality video recording option. What i am trying to say is; since rear camera has recording options ( sd, hd, full hd, 4k) the app is making the lowest quality selection by itself. When it comes to front camera since there is no option to choose the quality of front camera video recording then instgram takes the fixed one which is already full hd ( you can find video recording settings inside of camera app for both rear and front cameras) I believe this is done due to decrease the data consumption.
So now the case is if we can simply remove the option of 'SD Video Recording of the back camera' then we can post good quality videos on instagram
So if someone know, how the camera recording quality can be removed from the system please let me know
Thanks in advance

[Q] EIS in third party camera app

Hello,
I'm using Background Video Recorder regularly as a secret recording tool and I'm in dilemma for buying the Google Pixel phone as a new smartphone.
I want to know if the Electronic Image Stabilization will work. The question is valid for other camera apps which can record video.
Thanks!
No one knows or willing to try?:crying:
Personally, I'm hesitant to contribute to spying apps. I realize that there are probably legitimate uses but I know of more than a few less savory needs for a camera that records without looking like it is recording. I only hope you represent the former and not the latter. I bring this up only to potentially explain why other folks may have remained silent like I did.
EIS only works in stock camera app. Annoying for me because stock camera app doesnt seem to support external microphones via aux or usb, so I can't use EIS in Cinema FV5 when using a mic.

How to use the wide selfie camera in video calls?

Is there a way to select which front camera should be used in video calls? In Google Duo, for instance.
I can't find any option for that in Duo or settings and maybe I'm missing something, but it seems like a waste if the wide lens can't be used in video calls.

u can't do it. Same with snapchat u can't use other cameras.
Maybe the default camera could be swapped using Magisk or something along those lines. Any ideas how to do that?

Support for two USB DVR cameras

Hi, is there a solution to connect two USB DVR cameras (front and rear) to one application in a 2DIN car radio? I am using a dedicated application (xcdvr1) and it only runs one camera. Even when I clone the application, it only detects one camera and doesn't record the second one on both applications. Is there an application that can handle two cameras? Thank you in advance for your help."
Can Android's CameraX/Camera2 handle at the same time 2 Previews or/and 2 Recordings?
Is it possible using Android's CameraX/Camera2 to preview at the same time on the phone, the image coming from two cameras (e.g. the front and back camera)? The same question holds with recording.
