![]() ![]() This will lead to low quality footage & a substandard immersive experience for the audience. ![]() Otherwise each camera might record a slightly different moment in time per frame and you will get shifts in the panorama. However, when filming from a drone and therefore constantly moving sync is important. The downside with the Hero3+ is reduced resolution compares to the 4, so if you simply want the highest resolution possible then the Freedom360 mount with six Hero4’s would be best off-the-shelf solution. GoPro have said they are working on a solution for the Hero4 (in form of a firmware update) but haven’t said when that will be released (at July 2015, this still hasn’t been released). Right now (time of research March-May 2015), the only GoPro you can genlock is the Hero3+ based on the same technology as GoPro’s stereo kit which is only compatible with the Hero3+. We decided to use a GoPro, but had to make a decision between which model to use, the older Hero3+ and more recent Hero4. To get perfect sync with multiple GoPro’s, right now, you have to use the Hero 3+.įinding which camera to use was a process of elimination.Currently you can only sync using the Hero 3+. When they do there will be many options for higher resolution 360º setups. GoPro have not yet released a sync kit (a sync kit allows for image synchronisation) for the Hero4 their higher resolution camera.GoPro cameras are lightweight and allow lens adaptation for shooting wider angles.The Blackmagic Micro Studio camera is still much bigger than a GoPro (& therefore heavier and needs a larger copter to fly a rig) & not released until July 2015 (post r&d phase) – otherwise we would have used it for testing.Resolution: The Theta approach (Ricoh’s two lens 360º camera) actually produces great results, but resolution is very low.There are more and more 360º / panoramic stitching softwares available.The use of mirrors is the seemingly the only way to get perfect stitch but not feasible for small setups due to expensive optics.Tech note: A CCD (charge-coupled device) or CMOS (complementary metal-oxide semiconductor – a battery-powered memory chip) with global shutter is preferable but gets very expensive very quickly. As in 180, image syncing all cameras is essential in order to stitch a 360º image in post production.Tech note: Due to stereoscopic parallax flattening out at that distance. We have learnt that viewers don’t see 3D objects past 5 metres or so therefore 3D is not necessarily important for aerial footage as the subjects filmed are likely beyond 5m.However, whilst this is working simply, it is only 180º, and we want 360º. To do this the films being taken need to be perfectly synchronised (taken at exactly the same time) and have very good depth perception. This means that no stitching needed, stitching means connecting the edges of different films together to create one seamless whole. The simplest approach for creating a 3D VR experience (at the time of conducting research) is using a 180º camera setup. ![]() ![]() The first stage of working out which 360 model to pursue was to conduct desk based research. Considerations were the resolution of cameras, weight (affects payload & flight-time of drones) and the camera’s field of view. Our research was specifically being developed to explore content creation for virtual reality (VR) headsets – in order to give audiences anywhere, anytime, the ability to experience aerial perspectives in immersive ways. This helped us frame the best approach for filming aerially in 360º. We conducted initial research (see download) in order to understand the variety of technical capabilities of existing 360º cameras. This post is quite technical, and will need you to have some knowledge of film making for you to get the most out of it. We share their research below for those creators wishing to experiment with similar techniques. The aim of this combination of technologies (UAVs & 360º content) is to create an out-of body experience where the user feels completely immersed in the viewpoint of the drone. From the beginning of MLF’s collaboration on Project Daedalus, they proposed to explore aerial 360° content, potentially live-streamed, for virtual reality. ![]()
