If you’re streaming Netflix, watching video on a computer, the internet, an iPad or your smart phone, you’re looking at an MP4 video file.
To get a bit technical, MP4 is an abbreviation for an MPEG-4 file. This file contains video, audio and even subtitles.
The big advantage of MP4 is that you can edit your video. It’s easy too. If you have a Windows computer, you should have an editing program called Windows Movie Maker on your hard drive. If you own a Mac, you already have iMovie software on your computer.
