Since you asked your last question. I researched the actual bitrates that YouTube encodes/streams it’s videos at and found this great resource.
I may have been slightly off in my previous calculation of 360p bandwidth usage. I did not calculate for upstream traffic. (Also note: they are using the MAXIMUM values below. Actual usage will vary from video to video.)
240p
Bits Per Second (down): 400-500Kb
Bits Per Second (up): 5-9Kb
Data used per 5 minute video: 8.333MB
360p
Bits Per Second (down): 900Kbps - 1.1Mbps
Bits Per Second (up): 15-20 Kbps
Data used per 5 minute video: 13.333MB
480p
Bits Per Second (down): 1.5-1.6-1.7Mbps
Bits Per Second (up): 20-26Kbps
Data used per 5 minute video: 20MB
720p
Bits Per Second (down): 20+ Mbps
Bits Per Second (up): 320Kbps
Data used per 5 minute video: 37.5MB
1080p
Bits Per Second (down): 20+ Mbps
Bits Per Second (up): 320 Kbps
Data used per 5 minute video: 62MB
Oh, my goodness. I’ve watched just about every WW1 movie they have. I’ve used enough to bankrupt myself under the pay for play scheme. Somebody suggested I log into Comcast and see if they say. I’ll try that. Thanks.
