Whenever you go to a presentation it seems that most of the time they are using PowerPoint to help get their message across and adding video can certainly help. Video has certainly become easier to create even using your phone so it makes sense that you might want to add some relevant video to a PowerPoint presentation.
As long as you have the right format you can easily do this. Many video formats work such as avi, wmv or mp4, there are more but these are the popular ones.
If the video below I show you how to add the video and some of the options such as being able to trim it, change the sound, fade in and out as well as make it loop.
Just remember to take the video file with you if you are copying on to another computer and test that it works before doing your presentation.
