    OT datarate vs file size

    if doing VOD streaming on a metered connection: e.g. 500GB a month, etc, when talking only about streaming VOD, not progressive dl, is there a difference in the usage between

    One:

    big file size: 1GB
    same datarate: 1.5kbps

    Two:


    small file size: 500MB
    same datarate: 1.5kbps

    datarate + time

    No. A byte is a byte, no matter how you slice it or serve it.

    so i'd pay the same to stream one and two if they are both one minute

    Hi
    Yes that's correct as its the same amount of data.

    If the files are the same bitrate, the difference in usage is that the 500MB file uses half the bandwidth (cost).

    This is also true with progressive download. Note, Wowza live streaming will tend to save more bandwidth than progressive, especially if the user doesn't watch the whole video.

    If the files are the same duration, then the bitrate is proportional to the file size.

    what if the file size is the same but one is higher bitrate?

    If the file size is the same but one is a higher bitrate, the one with the higher bitrate will be of shorter duration, which sort of invalidates the comparison, don't you think?
