GoPro has released 3 new cameras including the Hero 7 Black which is now the flagship product for the company. The key feature is HyperSmooth which is a predictive stabilization technology based on scene analysis and sensor telemetry to accurately anticipate motion and correct the image to generate a gimbal-like smooth appearance to the video. When you see the footage it is clear it is a huge improvement compared to even the Hero 6 Black which had a pretty good stabilizer.
The Stabilization, however, is limited to 4k 30/60p and other resolutions below 120p but anything above 120fps will use the previous stabilization feature which is not predictive and have no stabilization support at all at 1080p 240fps which is the highest slow motion mode. No 480fps or other higher fps settings are available as the camera uses both the same Hero 6 Black sensor and the same GP1 system chip for this new camera.
