silverlight: creating video with timed overlays

just yesterday tim sneath posted a video on creating video with overlays.  as i saw that come in my reader, i was just finishing testing my code for a screencast i was recording on creating video with timed overlays.  i figured, what the heck, you can never have enough tutorials, and mine was demonstrating a different method for accomplishing the same thing.

the scenario i was thinking of came to mind when i was lazy and watching television.  i saw a commercial where the person in the commercial said "if you call the number that is at the bottom of your screen" and then the number popped up.  i thought this concept would make a good tutorial on using markers in media files.  for advertisers, this would allow media to be re-used, but leverage different messaging in the form of language, promotional offers maybe,  especially in the web space, you'd probably want to provide specific marketing depending on the placement of the media advertisement.  or at least that was my thinking...

anyhow, so i put the screencast up and added it to my TimCast feed.  it demonstrates first using expression media encoder (preview) to import a quicktime movie file recorded with my isight camera and placing media markers within the media, then encoding the file to a consumable format by silverlight.  the next step is leveraging expression blend 2 (preview) to render the media and add event handling looking for the media markers and responding to them with different animations and functions.

it's about 19 minutes, and might be some good peripheral learning.  i'm hoping to do more of these, so any suggestions of topics is appreciated...feel free to leave a comment about a suggested topic.
