Wich video format most compatible?

[Visions of Domi]

Hi,

I'm wondering... what video formats are most compatible and which should be avoided.

I know I should give viewers a choice... And I am... but I want to narrow it down to 3, max 3.

I love the quicktime format... I love it's MPEG4 (.mp4) format, is that a compatible format? Will everyone be able to view it?

Real .rm, is that a safe format to go with? I don't see around much. It's my second choice for quality.

I don't like using WMV format because its quality stinks! I do animations, and it gives horrible, saturated, watercolors in the rain effect.

So, I'd love to use Apple's .MP4 format... can I without problems? It should play if the user has quicktime, right? In which case, all my targeted viewers will have. If they watch videos, they must have it.


I'd like some insight on this.

Thanks,
Visions

Yes the newer versions of quicktime do support mp4 however wmv is most compatable with PC's because most users have windows and windows media player is usually installed by default. However avis will not play in Firefox unless the user has quicktime installed. If your target audience will have quicktime installed then mp4 should be okay.
