Before attempting to play the video file, first make sure you have unzipped the zip file. Generally you can unzip any file by right-clicking on it, and extract all (or something similar, depending on your operating system.)

After unzipping, make sure you navigate into the unzipped location, NOT into the zip file (after unzipping, you may wish to delete the zip file to avoid confusion). Then...

To view a video, double-click on the MP4 file (or WMV file).

It should open up in your default media player, such as Windows Media Player, Quicktime, or Itunes.

Depending on your media player settings, you will most likely need to click the play button to start watching the video.

It may take a minute for the video to start playing.

MP4 files and WMV files can both be played on Windows computers and Macs.

If you have trouble with your computer's existing media player, or if you need a media player, you can download the VLC Media Player for free at:

The VLC player can be downloaded for Mac or PC, and can play most video files in any format.

If you are attempting to view a WMV on a Mac, here is another free player (Flip4Mac) that will work:

To edit the videos, add music, crop the videos, and more we recommend you use the
free Windows Movie Maker Software. You can download it here:

If you are using a Mac you will need to have a copy of Parallels installed so you
can run Windows on your Mac. You can buy that software here:

In the video training we will also demonstrate other software tools you can use 
to edit the videos.
