This page is useful for deciding which is the most appropriate data rate for your web video.

Factor involved in deciding include:

  • Desired and minimum acceptable picture and audio quality.
  • Picture and audio types - a talking head on a plain background can look good on a lower data rate than a fast-cutting music video.
  • Time your audience will wait for downloading or buffering until playback starts.
  • Will your audience put up with annoying stopping of playback while more of the clip downloads or are they happy to leave the clip downloading while they do something else using another web browser tab?
