Small video files or sprite sheet animations?

Which do I use?

I have motion 5, which is a powerful video engine. I can make files as small as 14 x 14 pixels, which is the size i need for my game, the file can then be compressed. Alternatively I could use a sprite sheet.

Assuming this animation was a 2 second loop. which is more efficient ?

and if I don't care about the efficiency, which would look better?

thanks for reading!
