Streaming Format Comparisons
Current technology allows you to create streaming content of varying quality settings, sizes, and frame-rates making the best possible use of the different and sometimes inconsistent bandwidths. The examples below show how the same captured presentation can be delivered at different bandwidths and how the quality compares using standard settings. Bit rates range from 56k for a typical dial-up modem to 128k to 384k for those using broadband connections to 512k and above for those with exceptionally fast and reliable connectivity on high-speed connections such as Local Area Networks or T-1 lines. Examples of each supported format are provided below.

Real Media Helix 10 .rmvb file extension
Windows Media 9 .wmv file extension
MPEG-4 .mp4 file extension
Quicktime .mov file extension
Real Helix 10 SureStream
Real SureStream combines multiple bit rate streams in one file. Upon opening the stream, RealPlayer determines and plays the best bit rate for your connection. Your connection is constantly monitored and the viewed stream seemlessly changes between bit rates as network conditions fluctuate to present you with the best possible quality.
Flash Video
Flash Video can be served as a stream or progressive download. Here the same clip is linked both ways to demonstrate the functionality difference between the two hosting methods.
