Video Streaming Bit Rate vs File Size pmgreen
Newbee here, so please have patience. I'm involved on a capacity planning project for streaming video. One of our providers is delivering videos at 700k for a 20 minute video. What file size should I expect to see? Are there standard bit rate / file size?
Appreciate your help
The file size can be determined by:
(length of video in seconds * kbps) / 8
So if you have a 700kbps video that is 20 minutes long (1200 seconds):
(1200 * 700) / 8 = 105,000 Kilobytes
Note the exact number can vary depending on overhead like meta data, variable bitrate video varies too as will the method used for variable bitrate like 2 pass encoding.
