I create videos with Camtasia and use hotspots and quizzes. These interactions only work with the smartplayer. The interactions will not work on youtube, wistia or vimeo. I was thinking of using Amazon S3 to host my videos since I plan on making many videos and upload them to my website. Hosting on screencast can get pricey once viewers start viewing the videos and bandwidth usage increases. Hosting the videos on the site itself will weigh it down. Does anyone have any ideas on the best route to go here?
