Probably because videos take a relatively large amount of storage space compared to photos, and they would take very long periods of time to transmit. Seeing as how there's no real added value to a video versus a picture when nothing is moving, there's not a great reason to do it other than "because we can".

"Because we can" isn't a sufficient argument when arguing for the millions of  dollars in technology required to perform such a function.
