* Fix the URLs in the code:
** Reaplce the abolute "http://yourdomain.com/..." URL by "js.player" and css.player. '''Look at the code and think !'''.
** Change the name of the video files if needed.
** Change the name of the poster files, i.e. substitute "http://leanbackplayer.com/videos/poster/elephants_dream_640x360.jpg" by "myposter.jpg".
 
* Test: If the video does ''not'' show then you likely:
** must have put the JS  and CSS libraries in some other place (not the same directory). Fix the URLs, '''look''' at your directory !
** must have deleted some important line of code
** must have have syntax errors: validate your code
** Tip: Open the error console in your browser: In Firefox: Tools->Web Developer->Error console

* Get the HTML file done on Monday and add captions files, look at [http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html this example]
* You can start from this VTT file: [http://tecfa.unige.ch/guides/html/html5-video/subtitles_en.vtt subtitles_en.vtt] (rename it if necessary)


Create a Flash video with captions
If you missed class:
* Download and dezip [http://leanbackplayer.com/player_download.html?type=player LeanBack Player]
* Save the following file and start from there: [http://tecfa.unige.ch/guides/html/html5-video/html5-video-track-leanbackplayer.html html5-video-track-leanbackplayer.html]


* Encode a video with the Flash or the Adobe Media encoder (remove unwanted start/end of the film and select an appropriate output format)
'''(3) Creating screencasts:'''
* Prepare a flash "movie clip" that includes playback with the video component plus captions.
* http://www.screencast-o-matic.com
* You can choose any film you like, but preferably one that you made yourself (originality bonus)


Bonus points: Extra elements in the Flash page, interesting captions, good timing, etc. I.e. the result should look professional and be useful.
'''(4) Video and audio editing (part II)'''


I suggest that those who already turned in 3-4 homeworks skip this exercice. I will not test Flash in the final exam. I only require that you have some very basic understanding of timed text (i.e. use the "p" tag to define start and duration of captions ....)
* [http://windows.microsoft.com/en-us/windows7/products/features/movie-maker Windows Movie Maker]


When you upload the result, make sure to include all files needed to see the Flash clip, i,e, html, swf, component swf, flv, js. To get this right, I suggest to use a new folder for this project.
