What does bitrate mean, and how do I choose one?
Part 2. – Commonly used Bitrates (with examples)
Below is a list of common uses for internet broadcasts, with the appropriate bitrate to use for each. Simply find the description that best matches your needs to see examples of bitrates that may work well for you.
Note: Windows Media Encoder has many bitrate choices, the following bitrates are meant to act as guidelines only.
Video
Static image (speaker at a podium)
128kbps - This should generally be the lowest bitrate that is used for video. It can be used in situations where there will not be significant movement, or in situations where bandwidth or budgetary issues require a low bitrate stream.
Multi-use video broadcast (conferences, special events, sporting events, concerts, etc)
282kbps - This bitrate is the current internet standard for video broadcasting. Most viewers on a DSL, cable, or other high-speed connection can effectively view these broadcasts. It is generally effective for all video broadcasts (except in cases where a higher level of detail is required), although you may still wish to use a higher bitrate.
High quality video broadcast (weddings, sporting events, racing, etc)
548kbps - This bitrate will provide a higher quality broadcast that is often preferred by people whose broadcasts contain a lot of movement or action. It is also an alternative to 282k broadcasting if you want a higher quality. Note: Some viewers may have difficulty watching your stream.
Fast action video, high detail video, very high quality broadcasting
1128kbps - This is used for delivery of very high quality video broadcasts. Your viewers should be on a cable connection or better. This level of broadcast is necessary for quality broadcasting of fast moving events (sailing, car racing), and can also be very effective for situations that require a high level of detail. Often broadcasters will offer this in addition to a lower quality broadcast. The picture and sound quality is very good.
DVD quality video
2137kbps - A very high level stream that would be most effective for a specific audience, as many viewers may not be able to view it.
