You can insert the YouTube movies into your
PowerPoint slides to express
your
idea
or
better way to communicate
something. You can convey
these ideas in more effective ways, if you are using movie files with
your simple slides.
Follow the given steps to add YouTube movies into PowerPoint
slides:
First of all download the YouTube.com movies and then save on your
computer hard drive. Mostly movies are available in flash video file
format on YouTube site. You can convert also the downloaded movies from
YouTube into any common format, for example, windows media video file (wmv),
windows video file (avi) and movie file (mpeg).
First of all open the presentation in which you want to insert movie
file.
Now
click on
"Movies and Sounds"
option from the
Insert"
menu and choose the option "Movie
from File".

Now
select your movie that you want to insert into slide and click on Ok
button.

Here
now you are asked "Do you want your movie to play automatically in the
slide show? If not, it will play when you click it."

Recommend choosing Ok button to play automatically even if you want the
movie to play when clicked.
Finally save your PowerPoint presentation and run it for test.
