The GoPro Hero 9 is a capable action cam that snaps 20MP photos or can shoot 4K video at 30 frames per second. You can do 5.3K video at 30fps.
You can shoot time-lapse video on both cameras, although the newer model has a new version of the company’s HyperSmooth image stabilization system.
Whether you purchase a new GoPro or not, the GoPro Hero 10 is the superior choice, thanks to the company’s GP2 processor.
