The method of making micro-lesson video by PPT is as follows.

First of all, we should design the text script of the micro-course to be made.

Then prepare to use pictures, videos and audio materials to make PPT micro-lessons.

Then open the PPT production software and create a new PPT document. Install the designed process and insert the corresponding materials into the corresponding slides. Then set the necessary animation effects.

You can also insert the audio of the explanation into the corresponding position. After adjusting the order, you can save this PPT document as a video in mp4 format.

You can also explain it while putting slides, and record it as a video with screen recording software.
