[X3D-Public] videos of proper animation for example X3D scenes

The simplest solution is to provide the videos in the formats that are most
used by each platform. The most usable format for Windows. The most usable
format for UNIX/LINUX and the most usable format for Macintosh.

Definition of most usable: Operating system X will view Video Y ten seconds
after the computer OS is turned on and the video is downloaded from the
web3d consortium websites. No error screens, no other software needed. The
same no other software needed applies to the compression scheme.

I suppose that there can be some cutoff points. Example: only use formats
that are viewable on Windows XP and later or OSX Leopard or later. I don't
know what legacy cut offs apply to UNIX/LINUX versions.

mov is a quicktime/apple specific container. mkv or mp4 are more widely
Are there any suggestions for paper material submissions? Those must be
open. Maybe ACM has something up.
