I have no opinion on the need being adequately covered by other attributes, but…

For some videos a simple textual description is inadequate, just like
it is a poor proxy for some still images.  Yet for some other videos,
it is completely accurate.

I have no problem imagining a short video clip which fits your "A
young dog plays with a red ball on the grass" just as accurately as a
still image could fit that description.

An argument that an attribute is inadequate to cover *all* cases
shouldn't be used as a reason to exclude something which is useful in
many case.
