Re-edit the PowerPoint video over 3 times

Hi there

Please refer to the video URL below.

I think that the video above has been re-edited about three times for the　following reasons．

1. Inscription on each slide labeled as a presentation
2. Set animation for each slide
3. Create 1 and 2 with video → 1st time
4. Create a video again so that the text matches the part you want to explain with the magnifying glass → Second time
5. Enter narration → 3rd time

What do you guys think?
