Represents the number of bits per unit time and is used to indicate the quality of the ad or video. By default, this is indicated by bits per second (bit/s). The bit rate can vary across the entire video, for example, because it contains fewer colors or because the quality of the video is not the same everywhere. In general, the following applies here: the higher the bit rate, the better the quality. Because not every combination of device and internet connection can handle all bitrates equally well, it is wise to have several renditions (versions of the spot) available varying in bitrate, with a minimum size of 1500 kbps.
