good movie bit rate for members area?
 

What is good bit rate for movies @ mambers area?

For modem:

30s clips at 500kb/s or
60s clips or longer? smaller bit rate or higher?

For broadband:

Full lenght files maybe 1200kb/s ? or less?

THX

i use 700, 300 and 100 in my members area...plus a 1000 downloadable mpeg

Should i have full lenght files at 700, 300 and 100?
Or should there be also for example 30s clips for modem users at 500kb/s?

What´s good?

Is it bad idea to have just

30sec clips at 400ks/s for modem

and

full lenght files at 900ks/s for broadband ???

Any experiences?
