Teche posted a demo of its realtime optical flow stitching with realtime stabilization, which it calls Mixsteady. It remains to be seen if 20fps is a usable frame rate for 360 video. However, the Mixsteady frame rate is 20fps, just shy of the 24fps minimum creators and viewers have come to expect. For 30fps, Pilot One and Pilot Era’s resolution is limited to 4K (8K with in-camera post-stitching).Ī Teche representative said that with Mixsteady, the 360 Anywhere will have a resolution of 8K, which is 4 times the 4k resolution of the aforementioned cameras with realtime stitching and stabilization. Pilot One and Pilot Era can do 8K in realtime stitching mode but only at a framerate of 7fps. For example, when using realtime stitching mode, Insta360 Pro and Insta360 Pro 2 resolution is limited to 4K (8K in post-stitching mode). With cameras that have realtime stitching with stabilization, the resolution tends to be limited. Unprecedented resolution but limited frame rate I don’t know if this is a mistranslation so I’m still confirming it, but if this is literally true, this would be the world’s first 360 camera with such a feature. Teche claims that the 360Anywhere will soon be able to use realtime optical flow stitching. However, I’m not aware of a 360 camera that uses in-camera optical flow stitching for video in realtime, until now. For videos, there are software that can use optical flow stitching, such as Mistika and the discontinued Autopano Video Pro. Thus, there are several cameras that can use in-camera optical flow stitching but only for photos such as all the Ricoh Theta cameras and the GoPro MAX. The primary disadvantage of optical flow stitching is that it is usually more processor-intensive. Accordingly, optical flow stitching is one of the more commonly used methods for stitching stereoscopic 360 cameras, which have significant parallax by design. In many cases, optical flow stitching can produce a smoother stitch particularly where there is significant parallax error. bending lines, etc.) in order to stitch the images. However, even with such cameras, it is not possible to stitch objects at two different distances simultaneously.īy contrast, another form of stitching is optical flow stitching, where the stitching software alters the pixels (e.g. Some cameras are able to change the stitching distance and adjust it continuously. At closer or farther distances, there will be stitching errors, although in some cases, these errors can be made invisible with the correct shooting and editing technique. ![]() The disadvantage of the template-based approach is that it can achieve a perfect stitch at only one distance. The advantage of template-based stitching is that it is faster. There are different methods for doing this but the more common way is to stitch with a template with predetermined field of view, pitch, yaw, roll, and other attributes for each lens. Stitching is the process of combining images from two or more lenses to produce a single panoramic image. I’m still trying to confirm this with their staff. Now Teche claims their 8K 360 camera, the 360Anywhere ($3499) will be able to do realtime stabilization as well (in addition to realtime optical flow stitching). The few cameras that are able to do this include Insta360 Pro, Insta360 Pro 2, Pilot Era, and Pilot One. They can render a 360 video in-camera with stabilization. A handful of 360 cameras have realtime stabilization. In almost all cases, the stabilization is applied in postprocessing, using a phone or desktop. Many 360 cameras have stabilization that uses gyroscopic data and rotates the 360 photo or video to mitigate or counteract the movement recorded in the gyrosocpic data. Teche says the 360Anywhere will soon be capable of this feature. It promises that you’ll be able to use 360 video immediately, smoothly stitched and fully stabilized, with no postprocessing necessary. Realtime optical flow stitching with stabilization is the holy grail of 360 video. ![]() Here’s why this would be revolutionary IF true. They call the feature Mixsteady and if true, it would be the first 360 camera in the world with such a feature. Teche announced that they are soon releasing an update that will (may?) add realtime optical flow stitching with realtime stabilization to their 360Anywhere 8K 360 camera. ![]() Teche 360 Anywhere 8K 360 camera with realtime stitching
