How do I determine streaming video file sizes?
You can determine an approximation of streaming video file sizes by looking at the streaming data rate of that file. Depending on the compression scheme and encoding software, some streaming audio/video files may actually stream at lower or higher rates, but tend to average out to the data rate specified during the encoding process. Also, there is typically file header information that will slightly increase the file size.
The following table provides examples of streaming data rates:
|Network connection||Actual rate (in Kbps)||File size in one minute (in KB)||File size in one hour (in MB)|
|28.8 Kbps modem||20||150||9|
|56 Kbps modem||42||315||18.9|
|128 Kbps ISDN||100||750||45|
|384+ Kbps cable modem/DSL||250||1,875||112.5|
|750+ Kbps cable modem/DSL||500||3,750||225|
|10 Mbps LAN||1,500||11,250||675|
