Last year marked the return of one of THE big pioneers in the history of mobile phones to the smartphone market: Nokia. It’s not really the same company from the days of feature and Windows phones anymore (a company named HMD Global has licensed the brand name for their phones) but that doesn’t mean we should just ignore it. After launching a bunch of affordable entry-level and lower end mid-range devices (Nokia 3, 5 & 6), the Nokia 8 was the first quasi-flagship phone following the brand’s reboot.
One special feature of the Nokia 8 was something the company called the „Bothie“ for marketing purposes, obviously trying to convince people that a new flavour of the all-too-common „selfie“ is in town. A „Bothie“ is a split-screened snapshot that is taken with both front and rear cameras AT THE SAME TIME, giving you two different perspectives of the very same moment. For instance the image of a person looking at something AND the image of the scenery the person is looking at. What’s more: this mode not only works for photo but also for video, meaning you can record a split-screened video with both front and rear cameras simultaneously. It turns out however that Nokia actually wasn’t the first company to include such a feature in a smartphone. As early as 2013 (Samsung Galaxy S4) other phone makers equipped some of their phones with similar modes, HTC (One M8) followed in 2014, LG (V10) in 2015 – of course they are all using different names for the same feature so we can get jolly confused when talking about it!
Before giving a brief overview on how these modes have been implemented by each manufacturer, you might ask how such a feature can be useful for a more professional video production context. I’d say there are two main use cases for which this mode could be a great asset: piece-to-camera reporting and vlogging – obviously those two areas can heavily intersect. Imagine a mobile journalist reporting from an event, let’s say a protest rally – it’s much more interesting for the audience to see both the reporter elaborating on what’s happening and the rally itself instead of just one or the other. Traditionally one would have to have two separate cameras (or take different shots successively) and edit in post-production to achieve the same but thanks to today’s smartphones having HD video capable cameras on the front and the back, this can be done a lot easier and faster.
Samsung’s „Dual Camera“
As far as my research showed, Samsung was the first phone maker to introduce a dual video recording feature with the Galaxy S4 in April of 2013. This mode has been on all following Samsung flagships of the S- and Note-Series so far but you might have to download it as a sort of „plug-in“ from within the native camera app (there’s a „+“ button to add more camera modes). Samsung’s take is a picture-in-picture approach, not a traditional split-screen where both parts have exactly the same size (there IS a split-screen option but it’s barely useful with two 16:9 images side-by-side, extreme letter-boxing). With Samsung’s „Dual Camera“, one image always is the main image while the secondary image from the other camera is embedded into it. You can resize the picture-in-picture though and move it around within the main image – you can also swap between cameras during the recording. The recorded video file can have a resolution of up to 1080p with a traditional aspect ratio of 16:9 or 9:16. One very cool thing about Samsung’s native camera app is that unlike most other Android phones’ native camera apps it supports the use of external mics via the 3.5mm headphone jack or USB port which is a tremendous advantage for having professional-grade audio. One catch: You can only record up to 5 minutes for a single clip.
HTC’s „Split Capture“ (discontinued)
HTC followed Samsung with a similar but slightly different feature (officially called “Split Capture”) on the HTC One M8, launched in March 2014. The recorded video was an equally sized left/right split-screen 1080p video with a 16:9/9:16 aspect ratio. HTC subsequently featured this mode in other phones like the Desire Eye and the One M9 but apparently ditched it after the M9 as the HTC 10 and more recent flagships like the U Ultra or U11 don’t seem to have it anymore.
LG’s „Snap Movie“ / „Match Shot“
In 2015 LG redefined what a native camera app on a smartphone can deliver in terms of pro video controls with the release of the LG V10. But not only did the V10 have a unique manual video mode, the app also boasted some more playful features. Among them was a mode called „Snap Movie“ which basically invites you to create a short movie (maximum of one minute) out of short, different shots without having to muck around with an editing app. „Snap Movie“ is not a dual camera mode per se but one way of recording within this mode is to use a split-screen for simultaneously recording with both front and rear cameras. The image is recorded in 1080p with 16:9 or 9:16 aspect ratio. Big catch: You can only do so for a maximum of one minute! Flash forward to 2017 and the V30: While the „Snap Movie“ mode is gone (there’s something called „Snap Shot“ but that’s a completely different thing), there’s now a „Match Shot“ mode. With „Match Shot“ you can record a split-screen image using both front and rear cameras at the same time. You also have the option to select between regular and wide-angle lenses before starting the recording although the front camera actually only has one lens so it’s most likely a software crop. Two good things about the new mode: You are not limited to only one minute anymore and there’s also support for external mics. The recording format is a bit strange though as it’s a 18:9 or 9:18 aspect ration with a resolution of 2880×1440 (you can’t change the resolution at all). The beyond-FHD resolution is great but the rather non-standard aspect ratio (probably thanks to the 18:9 display of the phone) is a bit annoying for watching it on anything other than the phone itself because the image will either get letter-boxed on certain platforms like YouTube (I guess it’s not that much of a problem for Twitter and Facebook as they are more flexible with aspect ratios) or you will have to perform a crop in a video editing app and re-export in a more common 16:9 ratio. Hopefully LG will fine-tune this mode in the future, it would be nice to record in a standard 16:9 aspect ratio.
Nokia’s „Dual Sight“
As it has become quite clear, Nokia’s „Bothie“ feature introduced with the Nokia 8 last year is actually everything but new – HMD Global just made it an integral part of their marketing campaign for the device unlike their predecessors. The mode’s proper name is „Dual Sight“ and it’s pretty much like the one HTC had, meaning it’s an equally sized split-screen image in 16:9 or 9:16 aspect ratio with a resolution of 1080p. The Nokia 8 however DOES have one new trick up its sleeve: live streaming integration! You can use the „Dual Sight“ feature not only for recording but also for live streaming video on Facebook and YouTube (not sure about Periscope) which can come in really handy for journalists and live vloggers. One probable shortcoming of this mode on the Nokia 8: while I’m not able to test myself, I think it’s pretty save to say that Nokia’s native camera app doesn’t have support for external mics (the Nokia 5 definitely doesn’t). If you do own a Nokia 8 please let me know if my assumption is correct. Last bit of info: The recently launched Nokia 8 Sirocco and Nokia 7 Plus also seem to have the „Dual Sight“ mode.
All mentioned instances of dual recording modes have two things in common: You don’t get (as much) manual control over the image as you would in a ‚regular‘ video, it mostly runs on auto. And: the feature only works in the native camera app of the phone, third party developers can’t access the API to include this functionality in their own apps. There are a bunch of apps on the PlayStore that claim to do something similar but they only take pictures/videos successively with both cameras, not at the same time.
What do you think? Is it a useful feature? Do you know of any other phones that have a dual recording mode? Let me know in the comments below or hit me up on Twitter @smartfilming!
Is there any generic app that i can install on my oneplus 5t and enjoy dual camera recording simultaneously.
Unfortunately, there’s no 3rd party app available that can do that because the phone makers (so far) do not provide access to this functionality for developers. Some apps on the PlayStore claim they can do something like that but it’s never simultaneous. To use simultaneous dual camera recording you will need one of the mentioned phones from LG, Samsung or Nokia and use the native camera app. OnePlus to my knowledge does not provide this feature in their native app.
This is a great article, but I don’t want a split screen / picture in picture effect. 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 for the front and rear cameras. Do you know any phones that offer such a feature?
Hi! Currently I don’t know of any phone that can do that. Samsung has a dual recording mode that allows live switching of the two perspectives in full screen upon playback on the device itself but from what I can see, it’s still recorded into one file, not two separate files. You could however use two phones on a rig to get a similar effect, certain phone holders/clamps should be able to hold two phones back-to-back.
Tom, it’s quite possible that your current device is capable of that. Most likely, not at double full HD resolution.
I am wondeering can pixel realize same function?
Theoretically yes, the Pixel series definitely has more than enough horsepower to support this feature but I don’t think Google has implemented it in the Pixel’s native camera app. Maybe they would if enough people ask…
I have an LG-e980, its a few years old now, bought it just for the dual video PiP for YouTube vids.
That’s very interesting. I didn’t know LG had this on such an old device. I reckon the PiP looks like the dual recording Samsung has? Because the dual recording on current LG flagships isn’t PiP but an even split-screen.
Yep, pip, and you can resize and move around the inside frame! I want to say you can flip front to back while in dual record, but havent used the mode in a while.
Is there any company using the video feed from a front and back camera simultaneously within a video call?
If not, why not?
Infinix Note 4 was claimed as having this feature hence I purchased it, only to find this as well as scroll shot feature be removed after update, thereby whole purpose of purchasing for reporting and Evidence videos gone out the door right at the start & yes pretty high profile case so not suspicious at all what would have happened!
Infinix Note 4 runs MT6753 chipset from Mediatek, which has dual camera capability open to any user app (unlike the devices described in the original post). Unfortunately, there seem to be no decent apps on Play Store that you can just install and get simultaneous photo in both directions.
Thank you for putting together such an in-dept article. It may be worth noting that since the time of the original publishing of your article, some drastic changes have occurred. As of the Galaxy S9/S9+ and the Android 9.0 Pie updates, Samsung has removed the Dual Camera mode which offered simultaneous use of both the front and back camera. Additionally, Apple announced that they would finally be be adding the ability to utilize both font and back cameras simultaneously as part of iOS 13. Some interesting developments that seems counter intuitive to the direction Samsung and HTC have taken but with the rise of Live Streaming and online users broadcasting their every day lives, only time will tell which companies made the right moves.
