Introduction Technology is in a constant state of motion in video industry and even more so in the drone and
visualisation industry, that doesn’t mean marketing, visualisation and production companies need to
adopt every new trend, but one thing you might want to pay attention to over the next 12 months,
is 360 video and in particular 360 degree aerial video.
It’s a different form of storytelling, one of the most important things to consider with 360-degree
video, or “spherical video”, is that creators approach this format as an immersive experience rather
than a typical video. Unlike traditional videos including aerial videos, viewers have control over what
they see.
Simply, the viewer controls the recorded camera angle by tilting and panning on their computer or
mobile device via the video player. This can be an excellent tool for publishers that want to deliver
an immersive rich media experience: You could give your audience a fully interactive look at tourism
destination, castle, a house for sale, a new building, or even a sports or special event as examples.
Like ground based 360 degree video, aerial 360 can bring a whole new perspective and viewing
experience.
Like most new systems, there are some pitfalls, 360 video produces some amazing footage, but
because it’s a new technology there are some production downsides and challenges.
Drones for 360 degree video and camera systems At the present time there are no production / retail drones or 360 video camera rigs for them. If
required a 360 Degree Video drones will need to be built, developed and maintained specifically for
this purpose.
Cameras
The best 360 camera setups currently for drones, are built around multiple GoPro setups, with GP3,
GP3+ and GP4, with the 3+ and 4 being the preferred cameras. Although there are some consumer
360 degree video cameras, these tend to be low quality, HD or 4k system with small sensors. Several
high end systems are in development, but are thought to be either too heavy for drones or
extremely expensive at this time.

For good quality affordable 360 video a minimum of 6 GoPro’s will be required for video with no
stitching holes and good overlap. The weight of a good 6 GoPro rig and mount will be around 1.2kg.
Several mounts / holders are now available off the-shelf which lends them to drone mounting.
Airframe
The drone air frame needs to be designed specifically to carry the video camera payload for 360
degree video. Hexacopters make for a very good platform for this, they have a good power to weight
ratio. Hexacopters also give some level of redundancy should a rotor fail in flight, this coupled with
dual batteries give some level of confidence of your valuable 360 degree video gear.
Weight
For the UK market it is desirable that the drone be designed and built to stay under 7kg total weight.
This allows for flights to be made legally in urban areas and controlled airspace by a suitably licensed
and insured operator.
Drone in view
As much of the aircraft and its systems needs to be kept out of shot as possible, batteries and other
devices should be carried above the level of the rotors. A long pole carrying the camera pod should
be fixed directly in the centre of gravity under the aircraft. Too long a pole the camera pod will have
a pendulum effect; too short and too much of the drone will be in shot. Keeping the airframe a single
colour, mostly black makes it easier to mask the aircraft out in post if required. Although it is
relatively easy to patch the drone out in post, it is possible to have an extra camera mounted on top
of the drone, this can be dropped into the video in post, due to the distance from the rest of the
camera parallax may be an issue if subjects are too close.

Keeping the operator out of shot
Unlike other forms of aerial video it is near impossible to keep the operator out of shot, one of the
main reasons for this is that the pilot, by law must keep the drone in view at all times. This therefore
requires some thought to the positioning of the flight personnel during recording etc.
Landing and taking off
As most video pods are attached to poles hanging low underneath the drone, landing the drone can
be a challenge. Hand launch and landing is an option, or a specially designed landing support is the
preferred method for safety reasons.
Powering the camera systems (normally GoPro)
Most camera pods will consist of 6 or more GoPro’s, which are well known to be power hungry,
especially if Wi-Fi control is enabled. It is therefore recommended that the GoPro’s be powered from
the drone’s main batteries using suitable adapters and cable loom. There is nothing worse than one
of the GoPro’s shutting down in flight, or locking up due to a low or faulty battery.
Vibration
As will all cameras mounted to drones, vibration is a killer, “jello” can be a real problem and a
suitably designed vibration mount for the video pod is required. Hard mounting of the pod and
mounting pole can eliminate the “pendulum” effect, but the video will be un-useable, therefore
there is an optimum design of the mounting plate to comprise on this factor to get the cleanest
possible video.
Lighting
Low sun or strong contrast days should be avoided for 360 degree video, especially aerial. The
cameras pointing towards strong light sources will always be over exposed, even light is better for
360 videos, and for aerial work high sun position is preferred. A good 360 camera rig will have the
ability to fit ND or UV filters which helps manage rolling shutter which can cause issues when
stitching.
Camera Settings
All camera settings must be the same, settings are limited on GoPro’s, but typically GoPro’s will be
set for 1440p, 48fps and Protune, and manual WB. Higher frame rates are preferable as less
susceptible to rolling shutter.
NADIR
Nadir in 360 videos refers to an area not shot completely and appears as a “black hole”. Some 360
degree video pods on drones do not have cameras views facing upwards. This is acceptable where
the subject matter is below the level of the drone, however when shooting architecture or
visualisations such as fly through, then a full 360 view is desirable. For pods with no NADIR then the
drone can be “painted out” in post with masks as required, or if required clients logo’s inserted. Or
an extra GoPro / camera mounted on top of the drone.
Camera Levelling / Gimbal
Unlike normal cameras a full sphere is captured, and it is possible to level and stabilised in post
without loss of resolution and quality. However for moving shots a gimbal / stabiliser is preferred as
this minimises the amount of work required in post. Shaky shots result in headset viewers feeling
sick through motion sickness.

Drone Control frequencies
If using the GoPro Wi-Fi remote to trigger the cameras and start and stop recording, then for safety
reasons it is not recommended to use 2.4 GHz for control of the drone. (This is the normal control
frequency for most drones). For UK use, 459 MHz is a much safer alternative, and has an added
advantage that it does not suffer from issues such as multi-pathing in urban areas.
Video feeds.
To enable framing and monitoring of the drones systems in flight, a flight camera and on screen
display will be required, this is normally broadcast to the ground video monitor and pilot view using
5.8 GHz.
Editing and workflow.
While some consumer cameras do the stitching on board the camera, others require that you use
post-processing software. Programs like Kolor (acquired by GoPro), Video-Stitch, and PTGui are
popular for stitching. At the time of writing this blog, Kolor would seem to have the edge with its
Autopano Video Pro software, this coupled with Autopano Giga for stitching and preparation.

Editing this spherical content will differ from other video projects, but once the footage is stitched
together, you can use popular video editing programs like Adobe Premiere, Final Cut Pro etc. to edit
and colour correct. The main difference is the creative process for editing. It is not assembling a
sequence of shots to show an audience, but rather a 360-degree image that the viewer will have
control over when watching. You have to keep this in mind from beginning to end—from
brainstorming and storyboarding to shooting. The stitching and editing workstation needs to be very
powerful and capable of coping with editing 4k+ video as well as the heavy rendering for stitching.
Viewing 360 Degree Video
Online
Facebook: Now includes ability to upload and view 360 degree video, playback requires a suitable
browser such as Google Chrome, quality is lower compared to the viewer on YouTube. Max
resolution on Facebook is 1440p. Facebook by far is the best place to get the most views of your 360
video, many will view them on a tablet or mobile phone.
YouTube: Now includes ability to upload and view 360 degree video up to 8k, playback requires a
suitable browser such as Google Chrome. In reality most viewers will struggle to view resolutions
greater than 4k, unless they have a fast internet connection.
Mobile & Tablets
IOS: Kolor / GoPro offers a free player; most devices will playback HD, IPhone 6 is required for 4k
playback.
Android: Kolor / GoPro offer a free player, most devices will playback HD, newer quad core smart
phones required for 4k playback.
Desktop: Google Chrome, VLC Media Player and Windows Media also support 360 video playback.
Headsets
Google Cardboard
Don’t discount the Google cardboard concept as being gimmicky, far from it, it. More professional
looking versions are now available from @£10 upwards at online retailers, and these offer a great
immersive experience at low cost, as long as you have a compatible smart phone. Typical supported
smart phones include Apple’s IPhones, and Samsung’s Galaxy Note 3, 4 Edge and S6.

Samsung Gear
This headset is probably the best value for money versus performance and user experience at this
time. It is compatible with the Galaxy S6 edge+, S6 edge, S6, S7, S7 Edge and Note 5 Smartphones.
5.7 inch (143.9mm) Quad HD Super AMOLED (2560×1440)
Oculus Rift
Most 360 video players support the Oculus Rift, the Dk2 later version being the better of the two
headsets offering fully immersive viewing. Early DK1 headsets can suffer from motion sickness and
poorer quality.
HTC Vive
The Vive is similar to the Oculus above and can play 360 Video.

Video Domes
Video domes using multiple video projectors are the ultimate way to view 360 aerial videos. These
are fantastic for tradeshows, visualisation for construction and development projects. The downside
of video domes, are that they are very expensive and require very high quality video content,
typically 8k +.
Summary Just like live streaming, virtual reality technology has been around for some time now. However,
timing means everything when it comes to technology. With YouTube and Facebook investing in 360
video, both publishers and viewers will have the opportunity to distribute and 360-degree video
content to the masses to watch.
Another reason we think aerial 360 video will take off, is that it does not require viewers to wear a
virtual reality headset like it did in the past. While the headset option is there and promises a more
immersive experience, the audience doesn’t need to wear one in order to enjoy spherical video. This
simplifies the viewing experience and maximises the audience as the potential viewers do not need
to invest extra equipment to watch the 360 content.
To maximise the audience for 360 degree content, at the current time many platforms and devices
struggle with more than 4k resolution. Utilising 4k with a standard 120 degree FOV results in a
@1.3k pixel view port, which is slightly less than full HD. To attain a true 4k field of view requires
12,288 x 6144 pixels, a resolution that few devices can realise at the present time.

Cameras offering 4k resolution such as the Samsung Gear VR camera, Nikon and Theta S, can only be
described as consumer quality, for professional productions 6k+ is preferred for a good quality
experience.
If providing your audience with this type of immersive experience makes sense, then keep an eye on
360 degree video.
Turkey Red Media – 360 Video Production Capability
Turkey Red Media can offer both ground and aerial 360-degree video services.
At the time of writing we have a number of 360-degree video pods as listed below:
GoPro Omni, 6 x GoPro 4 Black, Genlocked, (8k max stitch)
6 x GoPro 3 Black (6k max stitch)
6 x GoPro 4 Black, (8k max stitch)
10 x GoPro 4 Black, (12k max stitch)
Stablised (Gimbal), 11 GoPro 4 Black, (12k Stitch)
Stabilsed 3 Axis gimbal for Kodak SP 360 Duo or Samsung Gear VR
3 x Kodak SP 360 4K (6k max stitch)
Samsung Gear VR
Whilst each GoPro records audio we prefer to use separate high quality audio recorders as
below:
Zoom H2N spatial audio recorder
Zoom 6N with wireless lapel mics for voice overs etc.
All of the cameras and pods listed above can be attached to our drones or ground based tripods. We
have two drones capable of carrying the 360 pods, our main aircraft is a custom DJI S900 with an 11
GoPro 4 Black pod on a 3 axis gimbal. We have a CarbonCore H950 with GoPro Omni used as a
backup. Both drones employ redundant designs and dual power supplies, and will recover from
propeller or motor failure. Flight times vary from 7-14mins dependent on batteries, temperature
and location. Each aircraft is designed to be under 7kg in weight, this is to allow for legal flights in
urban areas.
Turkey Red Media is also Google Certified and can create 360 imaging for Google street view and
virtual tours.
