In case of video delivery, especially where it isn't streamed its important to keep an eye on the bit rate which governs the file size and hence the download time before which the user would be able to see the video.
For a video length of say 3 mins following would be the size for different fixed bit rates - 1.25 and 5 Mbps -
1.25 Mbps * 3 * 60 = 225/8 = 28 MB
5 Mbps * 3 * 60 = 900/8 = 112.5 MB
File size = bitrate x duration
