Streaming video bandwidth

[KJStuart]

I don't really know where to put this and I realise this is a mostly hardware forum but hopefully someone can help!

I have a very odd problem. I am with Bigpond (ISP in Australia) and I get 500gb of usage every month. There are alot of computers in my household and a high internet usage is expected, but when we ran out of data last month I got concerned. I did some troubleshooting and installed Net Balancer on all the computers and came to the conclusion that streaming video was taking massive amounts of bandwidth, and I mean massive. When watching a 1080p youtube video, download rates exceeded 14mb/s and just watching a 5 minute video consumed a couple of gig! I have no idea why this is happening. Surely this doesn't happen to everyone. I used to be on only 25gb a month and be fine. 

 

 

Here is a screen capture of the programming I am using to test.

When this was captured, I was streaming a 1080p youtube video, it was 1 minute and 45 seconds in. I had reset all trafic before starting so watching 1 minute and 45 seconds of youtube downloaded 904.0MB's. Something is seriously wrong.

180p video's have big file sizes.

 

you may want to try your screen capture as you use firefox or ie.

 

if you have a cap of  500gb of usage every month. you may want to watch 720p or lower

sample

file   ( Info Updates and PF Gathering 2013.mp4 ) 7min video

1080p.......about   350MB..7min video

720p..........about 154 MB..7min video

480p..........about  60MB....7min video

360p..........about  40MB....7min video
