Stephanie,
Yeah, tough to address the keyword issue without having access to the actual video file to upload. If the creators are willing to, they can share the file with you via a service like Dropbox (for free) and allow you to download your own copy.
Once you have your own copy of the video files, you can upload to your company YouTube Channel and optimize with rich keywords. Make sure you do this for your titles, descriptions, and tags.
Tip: Before uploading your video, rename the file to include keywords for SEO.

Hope this helps!
