When stitching 360 videos, usually there is a compromise between quality and speed. However, Argon 360 is a hardware-based real time stitching solution that can stitch 360 video in high quality, using multiband blending techniques to minimize stitching artifacts.
The Argon 360 can stitch at video framerates with very low latency, making it possible to use it for livestreaming. For example, it can be used with 6 sensors (each at 1080 30fps) and stitch the videos to output 4k 30fps 360-degree video.
It is also scalable, and can be used with two sensors or several sensors, for consumer cameras or professional video.
