Pushing 360° Video Quality on a Motorcycle

I've been messing around with 360° immersive video at work.  One of the best ways to quickly get familiar with the technology is to use it in a difficult circumstance so you can find its limitations.  At work we're building immersive video to show a virtual walk-through of our school.  If the gimbal and camera we have will work on a motorbike, it'll work stuck to a kid's head as they walk through the school.

There are a number of barriers to admission with 4k video and image stabilization.  Fortunately, the 360Fly4k windshield mount I have is so over engineered that it easily handles the weight and motion of the gimbal and camera rig.

I've previously done 4k video with the 360Fly4k, but it has a big blind spot on it, so this would be my first true 360 4k video.  The Fly is a tough thing that takes great footage, but I'd describe it more as a 300° camera than a true 360 one.

This 4k 360 camera is the Samsung Gear 360.  I'm running it off the camera because the app won't run on my Android non-Samsung phone because I guess Samsung don't want to sell many of these cameras - it's kind of a jerk move on their part so if these things don't sell (because you have to have a Samsung phone to access it remotely), then they're getting what they deserve.

The Gear 360 has a small screen so you can see settings and using the buttons is fairly straightforward, though you'll find yourself constantly accidentally pressing buttons while you're handling it.  The Ricoh Theta 360 is still my ergonomic favourite in terms of control and handling, and they just came out with a 4k version of the Theta - perhaps they'll lend me one to test.

The gimbal is a Moza Guru 360°Camera stabilizer.  The typical gimbal design has weights to the left or right of the camera to keep things balanced, but on a 360 camera that means you're blocking all sorts of sight lines.  The Moza gimbal is vertically stacked with the weights hanging below, mostly out of sight.  It has a power button and a push button joystick that lets you set shooting modes and centre your camera so it's looking where you're going rather that looking down the 'seams' between the two cameras.

Most 360 cameras are actually two or more cameras working together.  The resulting footage is then stitched together in software to make an every direction video.  The raw footage from the Samsung looks like this (on left).  A front and back facing fish-eye camera capturing separate footage.

Because both cameras are capturing different scenes, you can often see where they are stitched together because of a difference in ISO which shows up as a clear line of brightness difference (on the right).  They all tend to be identical, fixed-lens cameras, so the aperture and shutter speed tend to be identical.

The first test video has the Samsung camera set at highest resolution (4096x2048 pixels in video) and 24FPS.  The gimbal is in locked mode, so it's always looking in the same direction even if I go around the corner.  The gimbal provides smooth video by taking the bike's motion out of the video (it's always looking in the same direction as the bike and I rotate around the shot), but a bike's motion is one of the best parts of riding, so for the second shot I set it in tracking mode so it followed the bike's motions.


Uploading it to YouTube out of the Gear 360 Action Director resulted in a flattened video that doesn't allow you to pan.  In order to produce that kind of video in the G360-AD (what a ridiculous name), you need to PRODUCE the video in the software and then share it to YouTube from within the program.  My issue with this is that when you bring the program in it takes an Intel i7 VR ready laptop the better part of twenty minutes (for less than ten minutes of footage) to process it before you can do anything with it.  When you produce it (again) for YouTube you end up waiting another twenty minutes.  The Ricoh Theta saves the video (albeit 1080p equivalent) in a fraction of the time and the resulting saved version is 360 ready for YouTube; the 360Fly software is likewise efficient at 4k.  I'm not sure why I have to wait forty minutes to produce less than ten minutes of footage on the Samsung.  I know it's a lot of data to work through, but it isn't a very streamlined process.

So, after a lot of post processing, the 4096x2048 360° video out of the camera shows up on YouTube at 1440s (s stands for spherical rather than p - pixels - spherical footage is stretched across a wider area and tends to look less sharp).  I'm not sure where my 2048s footage went - I imagine part of that big post processing was to shrink the footage to fit on YouTube more easily?

 If you click on the YouTube logo you can watch it in YouTube and adjust the resolution (bottom right) to see how it looks (make sure to do it full screen to use all your pixels).  If you're lucky enough to be watching it on a 4k display, this will come close to filling it.

The quality is excellent, the microphone remarkably good (they get beaten up pretty badly on motorcycles), but the awkwardness of post processing and the ergonomics of the thing don't make it my first choice.  Trying to manage it with gloves on would be even more frustrating.  What you've got here is a good piece of hardware let down by some weak product design and software.

The software does offer some interesting post processing options in terms of wacky arts filters, but if you're shooting at 4k all this does is drastically reduce the quality of your video.  If you're going to use those filters film at way lower resolution so you don't have to wait for hours while they process.

I'm aiming to go for a ride tomorrow to look at the fall colours after our first frost.  I'll bring the Samsung along and see how well it photographs.  It's promising 15 megapixel 360 images and high dynamic range landscapes, so I'm optimistic.  Photography is timeless and my preferred visual medium anyway, I find video too trapped by the continuity of time.  Maybe the Samsung will be a good photography tool.  Of course, I won't be able to fire the thing remotely because I don't have a Samsung phone...




Follow up:

The next morning I set up the camera on the gimbal for the ride to work.  The camera epically failed to catch any of the magic of the morning mist.  The video I got was starting and stopping every minute and the footage was a mess, full or artifacts and unusable.  

Compared to the robust Ricoh Theta (which I've had out in light rain with no problems) or the bullet proof 360Fly4k, which I've left filming through full on storms, the Samsung gave up the ghost at a bit of fog on an otherwise sunny morning.

This is not a tough camera by any stretch.  Dainty might be a better way to describe it.  For something that's supposed to catch the world around you, it's best used indoors.  Yes, I'm bitter that I couldn't catch anything of that glorious morning ground fog.

Simulated image indeed - this camera wouldn't work that close to an ocean!  If you're looking for a resilient, tough, outdoor camera, this ain't it.

Commuting on a Motorcycle

It isn't a giant commute - about a 15km round trip each day.  Our strangely summery autumn here in Ontario means I'm commuting on two wheels every day.  Over two weeks and ten commutes I've put over 150kms on the bike (I sometimes go the long way home).  What is commuting on a fourteen year old Triumph Tiger like?  Glorious.


In addition to actually looking forward to my commute each day, I (and the planet) are also enjoying the fact that I'm barely using any fossil fuel to do it.  In the past ten days I've used 6.88 litres (1.82 gallons) of gasoline to get to and from work; I've still got three quarters of a tank from my fill up two weeks ago.

The Tiger is currently getting better mileage than a Prius and didn't make anything like the hole in the world that the Prius did in manufacture.  My 0-60 in under 4 seconds Tiger is very nature friendly.


Other than a light rain on the way home one day it's been a dry time.  The bike has been fire-on-the-first-touch ready every day.  If I won't get soaked on the way in I'll take the bike (being at work with wet pants is no fun).  I could attach panniers and have rain gear with me (I've done that before on committed 2-wheeled commutes), but being only fifteen minutes from work means I and the Tiger travel light.  Riding home and getting wet means being uncomfortable for fifteen minutes, no big deal.

How long can I keep it up?  With the current forecast it looks like I'll be car-less until well into October.  The most recent forecast suggests a drop into the teens in the upcoming weeks, but I'll keep going until ice is a threat (I won't do that again on purpose).  Warm, never ending autumns are a lovely thing.


Unlike driving to work in the car, when I commute on the bike I arrive oxygenated and alert; it's difficult to cultivate the same level of alertness sitting in a box.  Showing up at work switched on and ready to go is a great way to start the day.  

With no morning radio I'm not as plugged in to the world, but that's no bad thing either.  Instead of pondering the latest human generated catastrophe (aka: the news), I'm gulping down morning mist and beautiful sunrises; it puts you in an expansive state of mind.

Soon enough we'll be into the long dark teatime of the soul (Canadian winter).  In the meantime I'm going to keep drinking from the commuting on a motorcycle fire hose.

Seven for Seven



Last week was a perfect 5 commutes on the bike.  This week I'm up to two already, though I got a bit wet on the way home.

If the weather holds I'm aiming for three weeks with the car parked!

A Glorious Morning


The ride to work -
fifteen minutes of
morning mist, 
warming sun, 
cool air,
filling my lungs
before the day begins.

Triumph Triples and Vulcan Bombers: Singing British Induction

I took a 360 video of our ride down the Forks of the Credit today.  

The video bit came out OK, but what was interesting was how well the microphone picked up the 955cc Triumph triple cylinder engine.  

Since it was out of the wind you get a front row seat to the mighty motor and its strange sonorous ways:


I've heard induction roar on a bike before, the Concours made a big whoosh, but the Tiger almost sings as it breaths.  It must be a British engineering thing.  Vulcan bombers used to howl when their air induction reached a certain point as well:



Why just make it work when you can make it sing?

Haliburton Highlands Fall Colours

With the weather beginning to turn we're in for a Canadian treat:  Fall Colours.  I think I'm going to aim for a couple of days out Haliburton way in October for a last big ride and a chance to soak up the colours.

Last time up that way I did Highway 60 through Algonquin Park.  This time I'm going to stitch together another route that is as different as possible.



Algonquin does a colour report that I'll keep an eye on and see if we can time a couple of days up that way when the colours are peaking.  Discover Muskoka does one too.  Last year we went up to the Kawarthas for Thanksgiving (early October in Canada): 







...and it was right before the colours changed.  Only the somac was in full colour.  I'll see if I can time it a bit better this time around at sync it up with a big last ride before the snows come.

Autumn on the Canadian Shield is a beautiful thing.

Waiting for it to Heat Up

It was a 6° morning, so I waited for an hour or so until the sun warmed it up to double digits.  The goal was to enjoy some curves on the last weekend before it's back to work.


I pushed north to Grand Valley and got a quick coffee at Brewed Awakenings before pushing on up past Shelburne and onto River Road out of Horning's Mills.  Finally, here were the twisty roads I'd been looking for.  South Western Ontario is a patchwork of tediously straight roads.  The exception is the Niagara Escarpment and this is one of the closest pieces of it.

Playing with vanishing point electrical lines













South out of Terra Nova Public House after a quick (and fantastic) bowl of hand made fish soup, I pushed south down the spine of the escarpment into Mono Cliffs and Hockley Valley.

By this point it was early afternoon and a warm, 22° late summer day.  Leaving the escarpment I pushed back across the barren desert of straight roads.
