Powerpoint 2010

I have searched the forum and found similarities but I need something unique.

I have a video in my slide and multiple text boxes. I need a text box to appear then video play for set time. (I have it bookmarked)



Then another text box appear and then the video continue to next bookmark.

And this repeats multiple times.

I also need this to happen automatically. One after the other without clicking.

I have been at this for quite some time with no luck. I am posting this with hopes someone can help me so I can finish tomorrow.

Thanks for the help.
