I maintain my company's knowledge systems. Multimedia videos have several problems:
- They are not accessible to the hard of hearing or the vision-impaired.You may be breaking the law unless you invest the effort to caption every single video.
- They are hard to search. Unless you create transcripts/captions or extensively meta-tag the videos it's really hard to find specific content.
- They are not easy to update. Generally you have to reshoot and re-edit the entire video.
- They take a lot of time and effort. Generally you can produce a text-based delivery that covers more knowledge in better detail in the same time it takes you to make a video.
I've seen several efforts to "video all the things". All have failed. Corporate videos are good for one thing - delivering "talking head" messages from management. After six months you can quietly drop them from your intranet and nobody notices.
