Background

In March 2017, I posted about a rumor from a Yi insider about two game-changing announcements on April 24.  Yi did not disappoint 😀

At that time, I surmised that the two announcements would be Yi’s Google Jump rig and a 360 camera.  It turns out that those predictions were spot-on.  At NAB Show 2017, Yi made two 360-related announcements: the Yi 360 VR and their version of the Google Jump rig called the Halo (which I’ll cover in a separate post).

However, what I did not expect that the Yi 360 VR would be the highest resolution consumer 360 camera with 5.7K resolution, higher even than the 5.2K resolution GoPro Fusion which grabbed headlines in April.  To put that resolution into perspective, the Yi 360 camera’s resolution of approximately 5760 x 2880 is 16.6 megapixels – higher than the photo resolution of the Ricoh Theta S (5376 x 2688) or the 2017 Gear 360 (5472 x 2736)!

Here is my interview about the Yi 360 VR with Yi’s Marketing Director at NAB Show 2017:

The camera is a little taller than a deck of cards and seems like it could be pocketable with the right kind of case.  I tried using it briefly and it seemed easy and intuitive to use with a backlit LCD display, and the shutter button and up and down arrows to navigate.

One of the most startling specifications is the price: $499 (originally announced to be $399), currently scheduled to be available in October 2017.  That is the same or less than some 4K cameras such as the Kodak PIXPRO Orbit 360 ($499) or Nikon Keymission 360 ($499).  It is almost half the cost of the Garmin Virb 360 ($749) and costs substantially less than the GoPro Fusion ($699).

Besides live streaming, special functions include time lapse mode with intervals of 0.5 seconds to 60 seconds.

Here are other facts about the 360 camera:
– removable battery
– removable storage (Micro SD)
– has a Micro HDMI port
– USB Type C port

According to Yi’s representatives, the camera can record for “hours” without overheating (limited by the battery life and the storage).  It can also supposedly live stream for one hour.  Yi’s representatives said the app will be on iOS and Android.  The specs say PC is supported, without mention of Mac (although the videos can be stitched on a phone).

Yi 360 VR image quality, sample videos, and comparison with other 360 cameras

On paper, the Yi does look amazing.  But what ultimately matters is of course image quality, and that’s actually the headline feature of the Yi 360 VR.  Here is a sample 5.7K 360 video with an analysis of the Yi 360 VR’s image quality and a comparison with other popular 360 cameras:

 

At 5.7K you can see details not otherwise visible
At 5.7K you can see details not otherwise visible

To summarize, as of October 2017, it has the best video quality among the more than twenty consumer 360 cameras I own.  Here’s why:
– The Yi 360 VR has very high detail.  Compared to a 4K 360 video, it looks more crisp.  You can see small details not visible in 360 videos from a 4K camera, like the thread pattern on my collar in the screen grab above (note that it’s only a screengrab from YouTube so it’s not even the original quality).
– Excellent edge-to-edge consistency in sharpness. There is no drop in sharpness even near the stitch line (with other cameras, most notoriously the Keymission 360, the sharpness drops as you move closer to the stitch line).
– Excellent dynamic range.  Can cope with backlighting and difficult lighting situations.
– No chromatic aberration or purple fringing.
– Excellent flare resistance with no reduction in contrast, but a few flare artifacts.  In my comparison against competing 360 cameras, the Yi 360 VR had the best flare resistance.
– Excellent consistency between exposure and color of the two lenses, even when one lens is facing a strong light source (with some cameras, you can see a difference in exposure or color between the lenses, usually most noticeable at the zenith).

Regarding stitching, the Yi 360 VR can stitch videos in-camera automatically but the stitching is template-based and therefore not so smooth.  However,  if I use the optical flow stitching from the supplied desktop software, the stitching looks seamless, even for challenging scenery such as repeating backgrounds.   It is also possible to stitch on a desktop with template-based stitching for faster stitching.

Here are other recent sample videos from preproduction versions of the camera:

As with my sample video, these samples show very high level of detail and edge-to-edge sharpness.  The images are completely free of chromatic aberration or purple fringing.  The dynamic range looks excellent.   Please note these videos are from preproduction versions of the camera and the final version will have improvements.

Yi 360 VR software, tutorial, and controls

Where to download the apps and software:

– iOS App:  from the App Store,
– Android app: from the Google Play Store.
– The desktop stitching app is for Windows only at the moment.  For Mac, you can use third party stitching software.

Tutorial:

Here is a tutorial by CreatorUp’s Hugh Hou (he is using the iOS version):

As you can see, using the app is pretty straightforward.  One note is that when establishing a wireless connection to the camera in the Android version, you can do it directly from the app, by simply tapping on the + button on the main screen (you don’t have to manually switch Wi-Fi networks). BTW, the default password is 123456789.

Other controls include:
voice control (to take a photo, record a video, or turn off the camera).
– specifying the ISO for photos (100 to 800) or videos (400 to 6400), and exposure compensation (+/- 2EV in half stop increments).
– changing the scene mode (auto, stage, or night).  Stage is for brighter conditions, and night is for dark conditions.
– controlling the exposure metering mode (center, spot, or average)
– changing the stitching distance (selfie, indoor or outdoor)
– a function for removing yourself from the photo.  You tap a person icon beside the shutter.   It will take 3 shots, 5 seconds in between, and you move to different positions for each shot (do not overlap the positions).  It will create a composite that removes you from the background based on the differences between those 3 shots, similar to an app for the Theta called Vanish360.   This is handy if you don’t want to be in the shot and there’s nowhere to hide.

Stitching

In-camera stitching is template based and is in realtime, but limited to 4K.  If you choose not to stitch in-camera, you’ll get a double fisheye file (interestingly, it is portrait not landscape orientation).  The desktop app can stitch with a template (for faster stitching) or with optical flow (for seamless stitching at various distances).  The desktop app can batch stitch photos and videos, which is a tremendous timesaver for your workflow.

Because the videos are unstitched in the camera, they can be stitched using third party software such as Mistika.  In fact, Mistika has a template for Yi 360 VR.  Third party software will allow customized stitching for difficult stitching situations such as when objects are in close proximity to the camera and are within the stitch line.


Image Stabilization

In firmware 1.1.34, Yi added a preview of gyro-based stabilization.  At first, the stabilization could only be viewed on the smartphone app but not in exported videos. However, in desktop app 1.0.3, Yi enabled exporting of stabilized videos. Please note the desktop app is Windows only. For Mac users, Yi recommends Mistika VR (tutorial here).

Google Street View

Yi 360 VR is compatible with Google Street View Mobile.  From the Street View app, you can connect to the Yi 360 VR and take either single photos, or interval photos.  In the latter case, it will automatically take photos based on a distance interval (not time interval, so if you’re stationary it won’t take additional shots).  In either case, the photos will be automatically stitched and sent to the Google Street View app, ready for upload.  If you took interval photos, they will be automatically linked.

Street View can automatically stitch and link mapping photos from the Yi 360 VR

Accessories

Yi 360 VR now supports external microphones
Yi 360 VR now supports external microphones

In firmware 1.1.41, Yi added support for external microphones.  The microphone would have to be plugged to a USB Type C to stereo adapter.  The external microphone support is very useful for live streaming, when an external recording device is generally not an option.   The Yi 360 VR becomes one of only a small handful of consumer 360 cameras with external mic support (the others include Insta360 4K, Kodak Orbit360, and Ricoh Theta V).

I tried a couple of USB Type C to stereo adapters, and the only one I found that worked is Yi’s own adapter, which is fortunately reasonably priced. Note also that the microphone must be TRS. If it is TRRS then you will need a TRRS to TRS adapter.

Summary

In summary, the Yi 360 VR is the most affordable 360 camera for high resolution 5.7K 360 video.  Despite its affordability, it offers amazing video quality with nearly flawless optics, excellent detail and dynamic range.  If you are looking for an affordable 360 camera with high quality 360 video, this is it.  The Yi 360 VR is now in stock on Amazon and in Microsoft Stores.  You can also try B&H Photo here (not yet in stock).  Here is a new Facebook group for those interested in the Yi 360 VR — I’ll be posting info about the Yi360VR there.
