Chris,
Nice job.
For your work, stills would document the project completely. I'm not so sure video for documenting purposes would fill much of a role. I think if video was brought in, it would be on a much more artistic level. This is really the only case I have seen for video in architecture.
Someone mentioned 3D. I'm not sure it's any better than virtual tours. Some of us know how much of a pain those are creatively and financially.
I've been thinking about creating short films for specific projects, but I'm sure it would take years to craft such a skill to my extremely critical satisfaction.
