Bit rate is a measure of how many bits of data are transmitted per second. Compared to videos with a higher bit rate, the same videos with a lower bit rate would most likely have

A lower bit rate means fewer bits are available to represent each second of video. This usually reduces image detail and can make motion look blocky or pixelated. A higher bit rate generally produces better quality but a larger file, so the correct choice is “blocky, pixilated motion.”
