but i cant follow 100% what he is doing.
Guide that i did try to follow is at this link: How To Create A Website Background Video In Adobe Edge Animate Using Edgehero - YouTube
Steps i do in Adobe Edge Animate CC
1.) Create New
2.) i click + sign under section Library >> Scripts >> Add JS File from URL...
URL that i am adding is: http://www.edgehero.com/edgehero.js/1.2/edgehero_1.2_min.js  (URL is taken from site: Edgehero.js )
I add this link: http://www.edgehero.com/edgehero.js/1.2/edgehero_1.2_min.js to box that occures after i click on Add JS File from URL
3.) I go to Edgehero.js and from there i scrol down to section named as Media - Html5 video / Html5 audio
and i select from there this:
there is a code:
  // this will set the video as background of the div/rectangle
backgroundvideo_1 ='movie.mp4';
  // put new edgehero.js variables here
4.) I go to Adobe Edge Animate CC 2014 and right click on project and select Open Actions for "Stage"
and then i click on + sign and select creationComplete
This will open Stage window
there i will copy this code:
  // this will set the video as background of the div/rectangle
backgroundvideo_1 ='movie.mp4';
  // put new edgehero.js variables here
5.) Then i click on ++ sign under library >> Video
and i add video from my computer SSD drive.
Video is named as video3.mp4
Now i eddit the code in Stage window (See above)
code will look after editing like this:
Then i change under left side px to %
6.) Then i copy backgroundvideo_1 from Stage Code:
Then i select Rectangle Tool and mark the area  (white box) and i click on small C icon
And the box that occures i type there backgroundvideo_1_mp4 autoplay
now when i use ctrl and enter i only get gray box that does not play video.
What am i doing wrong?
