I'd like to weigh in on this as there are severl things I might be able to add value with.
1. Jacki is correct about the process of adding a video and that there are other hosts. Every commercial video host I know, has the player inbuilt so the process is generally very similar. The differences lie in the functionality and benefits each host brings. SBI! has a list of video hosts in resources; http://sbiresources.sitesell.com/#VIDEO.
2. To Igor's question
Does it always have to be a youtube video?
The answer is a resounding no. This is not the place for me to get into a conversation but Igor you may find this article (and it's linked series) useful: http://sbitips.sitesell.com/adding-video-choices.html
. NB - this still refers to JWPlayer having a free player which they have discontinued just recently. The articles have been updated but not uploaded yet.
The bottom line is that you should choose your video host based on the kind or results you want from it and how you plan to use it. If you trawl through the video forum I have written about this a bit; viewforum.php?f=12
or if you want to ask a specific question over there, you can.
3. And finally, Carolyn
I was thinking I could have the video transcribed and then people could choose to read it and/or watch the video... and that would add words to the page. What do you think about that idea?
YES! with caveats... Again, this is a huge subject but may I point you to: http://sbitips.sitesell.com/video-trans ... tions.html
It mostly deals with YouTube and again, the article is slightly out of date (new one soon!). But you are definitely in the right ballpark. In summary - adding Captions (CC) to your video and then take advantage of the SEO advantages is a good plan.
Hope this helps
