Im one of the osmo action user. Im not sure is it possible to add function for low resolution with HDR and rocksteady together in the next firmware. I dont want the best res. but i want to capture the best moment with the features that already have in the camera. I just switch from gopro and dont want to go back if i can vdo HDR and rocksteady together with low res.

720P HDR and Rocksteady, GOOD LUCK!!

HDR on OA is not that great, so I can recommend just shooting in one of the normal resolutions with Auto on Shutter/ISO.

More or less we use ISO  to gain brightness but adds grain.
