PPT 2010 has added lots of very good video editing tools. In working on a recent project with many videos I happily made use of the Trim feature to set custom start/stop times. But after using a calculator to figure the new section duration (for over an hour), I discovered a new function!
Here is my sample video freshly inserted. The End Time shows the duration of the whole video.
Here is the sample video with custom start and stop times setup. Note the upper right corner where PPT is smart enough to automatically calculate and display the new duration of the video (yeah!)
