What is the difference between recording with DJI FPV Goggles V2 and with the camera on the aircraft?

DJI FPV Goggles V2  only record transmitted footage in a resolution of 810p/60fps, and do not support Electronic Image Stabilisation (EIS).

DJI Avata and DJI FPV Drone cameras supports up to 4K/60fps video recording, as well as benefit from DJI EIS.
