And now that MAX is out in the wild, we want to share the backstory of some of MAX's inner workings that tech specs at face value, especially in 360 capture, just can't convey properly. It is the anti-vibration stabilization applied in camera.

When we developed Fusion, we set the industry bar very high for stitching and blending, and we did so by combining the overlap on the 194° dual fisheyes.With MAX, we are proud to say we are again setting the bar by retaining the small overlapped areas inside the EAC projection. 安定化機能「Max HyperSmooth」を採用し、水平維持機構も備え、スムーズなビデオ撮影ができる。 安定性の高い防水シングルレンズカメラ、デュアルレンズを使用した360度カメラ、ユーザー側を向くディスプレイを装備したVlogカメラの3通り …

Once more tools start to support EAC, we will be able to skip this conversion step altogether and save even more time since no reprojection is needed.Another huge advantage of EAC over the previous standard (dual fisheye) is that there is no need to encode unused pixels. File sizes get even smaller with one final MAX advantage. 4032x1344 is very easy for all UHD decoders play back. Capture immersive 360 footage in 6K! So, we built a special player that can decode both streams in real time and re-project them into a sphere. While the stitching is completed in MAX, the blending is enhanced by retaining a small overlap in post to improve quality even beyond that of Fusion. With MAX, we are also encoding in HEVC, and 60Mbps in HEVC is equivalent to 90Mbps with H.264. Where the stitch aligns the front and back images, automatically correcting for near and far object parallaxes, the blend balances the exposure differences between the front and back lens. We are excited to see this come to life as MAX gets into the hands of 360 enthusiasts.#GoProLiveIt Weekend Charity: Challenged Athletes Foundation#GoProLiveIt Weekend Charity: Challenged Athletes Foundation Notice the savings in pixels since we don’t have any redundancy, and everything is equal area.

Take resolution for example, specficially the difference between capture and stitched resolutions. MAX out the radness. With MAX, spherical videos are captured at 6K resolution and stitched to 5.6K, and spherical photos are captured at 18MP resolution and stitched to 16.6MP.

We did this by adding overlap areas on the stitch line and increasing the width of the EAC projection by an additional 64 pixels.The image below shows overlap areas outlined in red.The following image shows these areas blended correctly. And if said decoder can decode one 4032x1344 file, it should have no problem decoding two. Most decoders are only optimized around UHD (4K), which is 3840x2160—that is a difference of 6,156,288 pixels! You can see this in action with the Now, on to the next challenge.

So, we knew that encoding to the 5.6K resolution wouldn’t be feasible, but if we changed the projection, we could fit the same amount of resolution into a much smaller container size.By breaking the top and bottom faces of the cube map into two separate video tracks, this creates two videos at the resolution of 4032x1344. 32 bit systems are not supported. Two different resolutions, one incredible output—read on to find out how. Two different resolutions, one incredible output—read on to find out how.To get started, it’s best to look at the key goals we identified when we started developing MAX:In order to achieve these goals, we focused on the following key technical areas:Thanks in large part to the power of the GP1 Chip that is the heart of MAX, we are proud to report that all of these goals are achieved with MAX. This ERS compensation is a key factor in stabilization. This is now much faster thanks to it being packaged in a stitched EAC format.Because of this success, and knowing that Google is also using EAC to power YouTube 360 playback, we really hope to help in propelling EAC as the future standard. With MAX, spherical videos are captured at 6K resolution and stitched to 5.6K, and spherical photos are captured at 18MP resolution and stitched to 16.6MP. 本当に使える360度カメラをお探しですか？この記事は最新のGoPro MAXについて解説しています。今までの360度カメラから一気に進化したGoPro MAXはとても使いやすくなりました。360度カメラをお探しにの方は必見です！

Quik For Desktop Single-lens HERO and dual-lens 360 camera. This means even better compression for the encoder since like pixels move less between frames, and this has proven to significantly reduce compression artifacts alone.HEVC, EAC projection and ERS stabilization done on camera all give Max a huge bitrate advantage over our competition, and we are confident you will be very pleased with the quality of the resulting video thanks to this complete new package.With the combination of optimizing around projection and splitting up the video into dual tracks, the resulting 5.6K video from MAX will give 360 content a huge boost in playability and quality over anything we have previously seen.

Finally, another big bitrate advantage is that we are now doing Electronic Rolling Shutter (ERS) compensation on the camera before it hits the encoder; unlike Fusion, which did this all in a post-processing step. We can compact the same number of pixels in a much smaller container.Now let’s talk stitching and blending. We still needed to provide users a way to convert these .360 files into standard videos or convert them into the larger equirectangular projection for upload to YouTube or 360 editors, such as Adobe Premiere Pro and Final Cut Pro. However, when faced with a camera that captures source resolutions of 6K video and 18MP photos, even with the power of GP1 on our side, some tricky challenges arose.For example, once you have a 5.6K stitched equirectangular video, that is equivalent to a resolution of 5376x2688, which is near impossible to encode with a modern encoder and, to make things more challenging, most high-end devices (PCs and smartphones alike) struggle to decode such a large file.
