MP4 (MPEG-4 Part 14) is a versatile container format that stores video, audio, images, and subtitles.

: You can create MP4 recordings using tools like VEED.IO or standard software like Zoom , Google Meet , or PowerPoint 's recording feature.

: Tools like FFmpeg allow for advanced command-line editing, such as creating 30-second previews for a series of files (e.g., ATL 101.mp4 to ATL 110.mp4 ).

: Most modern operating systems open MP4s automatically. Double-click the file to use default players like Windows Media Player or QuickTime .
