With GoPro Hero11 Black, you can record your videos at a highest resolution of 5312 x 2988 at 60p,30p, 25p, 24p fps with bit rates up to 100 mbps and save in H.264 and H.265 formats. This means that GoPro Hero11 Black provides an impressive 6K video, only second to 8K cameras in high resolution. Although it is not a very widely used format, it gives the user enough extra room over 4K to do cropping or high quality sampling in post-process.
Hero11 Black features a high speed mode where it captures videos at 240fps which helps to create slow motion videos. If you shoot a video at a frame rate of 240fps and play it back at 24fps, the video will be 10x slower and longer than normal.
Hero11 Black has a built-in Yes microphone and a Mono speaker. On the other hand, GoPro Hero11 Black doesn't have any connections for external microphones and headphones. If you need a Action Camera camera with external microphone connectivity, consider or in a similar price range.
GoPro Hero11 Black also features an Digital Video Stabilization mode where videos are stabilized in-camera while you are shooting. Keep in mind that this effect may crop your videos a little bit and doesn't help stabilizing still images. This kind of video stabilization effect can be replicated by using some of the advanced video editing softwares in your PC.
