The New Technology of the GoPro MAX

The technology of the GoPro MAX - the way in which 360 videos are acquired and compressed - is very different from that in prior 360 cameras. The standard technique is to use conventional compression applied to the spherical frames acquired by each lens. Then these were projected and stitched.

The new technology is not at all just using HEVC rather than H264.This statement by a GoPro software engineer explains in detail with examples of what goes on in the camera now.

https://gopro.com/en/us/news/max-tec...3302a50a24060c

Excerpt: "Previously, we had to encode a round image into a square container, leaving the encoded edges completely unused. With EAC encoding 25 percent less pixels than Fusion, we can achieve a net bitrate increase even though the overall bitrate is less, meaning much smaller file sizes. File sizes get even smaller with one final MAX advantage. With MAX, we are also encoding in HEVC, and 60Mbps in HEVC is equivalent to 90Mbps with H.264."

and a Unique Feature: Power Pano

270-degree panorama with one click - no panning. So no problem with moving subjects, unlike in all the standard panaorama techniques. Automatic horizon level, which for panoramas is critical. Also, stabilization, so can be handheld.

Example:

Example:
You have the Max? Nice looking shot. Mine arrives tomorrow. Nice to know GoPro is not wasting bandwidth on unused pixels, good insight.

My understanding is that no EIS camera offers stabilization for still photos, unless you count image-stacking "night mode" The one-shot, automatically level, ready to post pano thing is nice, can't wait to try it, am curious how it'll do vs. rendering a pano from the Theta Z1.

The Hero8 Black has already impressed me with its stabilization (not to mention its snappier interface vs. Hero7 Black) and I am looking forward to trying the Max.

More panos: indoors, low light

Tried the panos indoors.

Oh, the MAX Does Shoot 5.6K 360 Video: Test Example

This makes no use of stabilization, as the camera is set one in one place. But you can inspect the video quality. Workflow: GoPro app stitched to Cineform (900 Mbps!) video, ingested in Resolve and injected with 360 metadata after rendering.

I don't understand it. If it's 360 degree video than why are people walking out of the frame? I'm thinking I should be seeing them like eyes in the back of my head or something. What's 360 degrees about this?

Okay, I see now, directional controls in the player. Pretty cool!

If you are watching on a PC, you use the mouse to move around the video manually - you can follow those people as they walk by moving the cursor with them. You should not be seeing the equirectangular view, but a slice of the 360. Click on 'Youtube' to go to the YouTube site to view the video, not the little one embedded in the post. If viewing on a smart phone (on the YouTube site) , you move the phone to change the view - pan the phone to follow the walkers. If you are viewing on an Oculus Go or other VR headset, you swivel your head to follow the walkers, just like in real life.

I just checked it, works fine, if you go to the link.

The panos are only stills.

Nice and clean stitch there, comparatively the Fusion tended to have a more obvious seam.

Right now you can only stitch the videos using a GoPro Windows program ("MAX Exporter"). Then you can take the stitched files into any editor. The 360 video I posted consists of clips stitched in the Exporter and then the video was put together in Resolve, then injected (a simple free Windows program) with 360 metadata.

On the GoPro website it says that a Windows program, like that for macs, is coming. That will permit making FullHD those flow stream videos using keyframes. Right now you can do all of that that on any smartphone (stitch and reflow).

The new Kandao QooCam 8K - https://www.kandaovr.com/ - is the first consumer 8K 360 camera, and is being advertised as "Beyond the Max"

Not available yet, but one to keep a (fish)eye on.

The 1080p video from the MAX often looks better than the Hero8 because the lens is so resistant to flare and ghosting. It's truly an amazing device. And the auto horizon leveling is a dream. I hope future firmware updates add more capabilities.
