difference between promotion video and promotional video?

[Torsten]

So what is the difference between "promotional video" and "promotion video"?

Thanks,
Torsten

First of all, I'd like to mention that I don't think it too likely that I would actually use "promotion video". However, this is how I would interpret the two:

A promotional video is a video which is used to promote a product or service.

A promotion video would be a video showing how a promotion was carried out -- a video of the promotion itself. It might even be a video of John being promoted to head clerk.

I used to work on the scripts for promotion videos and promotional videos, and they are the same thing.
