Answer by Bibhuti Bhusan Routray:
A SD video amounts to about 700 MB per 2-hours and 400 MB per a 30-minutes. Provided below are approximate file sizes for SD & HD videos on multiple platforms.
Considering the above table, a 2 hours long video on TV will end up consuming 700MB if it’s streamed in SD and 3,600MB if it is streamed in HD. All you need to now do is multiply this with the number of video views you have in a time-frame you want to calculate the bandwidth consumption for.
700MB x number of views in a time-frame
700MB x 100 views to the video in a month = 70,000 MB or 70 GB of bandwidth consumed by THIS video in a month
You can repeat this calculation for all the videos in your library multiplied by the number of views you expect in a month to reach the bandwidth consumption by your VoD Platform / Video Streaming Site in a month.
