How is video bandwidth use calculated?
Bandwidth is a term we use to refer to the total monthly amount of data transmitted each time your video is played. The units we use are GB (Gigabytes). The Video bandwidth is calculated by multiplying the amount of plays, by the size of the videos. Note this is not the original size of the video you upload but the size of the video after we encode it, which is generally always smaller.
Encoded Video File Size x Number of Plays Per Month = Video Bandwidth Usage
As an example if you upload a 10MB file, and when we encode it let us say it is 5MB, then this is the data streamed each time that video is played. In this example lets say you had a 300 plays then your bandwidth consumption would be approximately 1,500MB or 1.5GB (5MB x 300 plays).
Note this is a very rough, ballpark figure. The figure will differ in reality for a few reasons: we have to deliver a player and poster frame for every video; initial propagation of your videos through the CDN that we use to deliver your videos will use some bandwidth; some modern browsers pre-load video data (even though we ask them not to) which can result in some bandwidth use from just loading the player (i.e. an impression).
