Using MP4 format files is standard in education due to their high quality, small file size, and compatibility across devices (computers, tablets, phones).

Clear audio is more important than high-definition video.

Focus on a single concept, ideally under 10 minutes.

Students can pause, rewind, or skip ahead, allowing for individualized mastery.

Every student receives the same quality of instruction.

Teachers often provide instructional videos to watch at home, reserving classroom time for active learning and discussion.

Short, focused MP4 clips help teach specific skills (e.g., a "how-to" video) rather than lecturing for an hour.
