file size:
movies can get big fast when rendering. a 30 second movie fly-through could be as big as 300 Mb. this giant file size is way too big to e:mail. what you have to do is reduce the file size by scaling down the size of the viewing window or by creating the fly-through in segments and e:mailing each segment seperately.

a good e:mail size is 2.3 Mb to 3.0 Mb

and a good size for websites is 4.0 to 4.9 Mb.

the e:mail size corresponds with the size of the viewing window, 160 pixels wide and 87 pixels high. this rescales the original image to 16% of its original size and records the fly-through movie at 10 frames-a-second, instead of the suggested 30 frames-a-second.

the web size fly-through movie window size should be 243 by 130, which is 24% of its orignial size and records the fly-through at 12 frames-a-second.
