Step by Step Tips....
When you have a trouble with inserting a video file into PPT
1. That's probably because the format of a video file doesn't fit in PPT.
2. Convert the video file format into wmv.
3. Open the window movie maker
4. Open the video file and save it as a new name. It's saved as wmv.format.
5. Open the PPT and try to insert the converted file in there again.
or we can use online conversion sites to convert a file into a different format file.
Thanks, Jeff. Like I said, you're a generous magician. ^^
