Cutting to the chase, low bitrate video compares poorly with high bitrate video, even from the same camera. This is going at compare the same camera. different bit rates, the hard way but... All video is 1080P@60 fps - the YT video's have been transcoded to 4K to avoid YT compression damage. The FDR-X3000 is running a 46 Mb/s - nice image, but not the SJ8Pro. The SJ8 is running at stock 26 Mb/s. The side by side sux. This is the same SJ8, as seen above, SJ8Pro running at 36 Mb/s. Same camera, different bit rate. I think this clarifies that bit rate isn't just a number for bragging rights.
