Bandwidth usage?

I've been experiencing random jumps in my bandwidth use, and I'm trying to figure out why. I suspect that ever since I started watching HD anime rather than SD, my bandwidth use has jumped considerably. Unfortunately, since I live in Canada, this has at times cost me an extra 30 dollars per month in overusage fees...

So, my ultimate question is: Is there any way that I can look up the size of the videos on CR? Or can you give me some approximation of the average size of Crunchyroll's SD videos VS. 480p VS. 720p?

Thanks very much!!!
Pamela.

This equates to data rates of about 1.56Mbps for 720p, 833Kbps for 480p, and a mere 305Kbps for SD. I seem to recall data rates higher than these being listed elsewhere in this forum. Are the actual maximum bitrates set for encoding in fact higher, but these are the typical results?

In real life testing, I found that higher download speeds were necessary for seamless playback since you also need to take into account that the videos and subtitles are DRM'd and streamed over RTMP. The amounts I listed in the following help topic show the lowest values that I confirmed work for each video quality.

http://www.crunchyroll.com/help?topic=video#4.1

For SD videos, a speed of at least 600 kbps (0.6 mbps) is needed.
For 480P videos, a speed of at least 1500 kbps (1.5 mbps) is needed.
For 720P videos, a speed of at least 2500 kbps (2.5 mbps) is needed.


I should have mentioned that before since it's probably useful info. So, pneddi, you could end up using double the amount of data that I listed.
