History of the MP4 file.

Created by the International Organization for Standardization International Electrotechnical Commission, MP4 was first introduced in 2001, based on Apple’s QuickTime format.

It contained low-data technology for the web, including audio and video files. The MP4 file as we know it evolved in 2003, becoming MP4 file format version 2.

As the chosen format for the Apple iTunes Store video files, the file type’s popularity grew even further. While Apple may have been responsible for the initial popularity of the MP4, it soon became the default file type across a range of media players.

How to use MP4 files.

MP4 files are ultimately used to store audio and visuals (video and still images) in small file sizes. If you play videos or edit them, chances are you’ve come across an MP4 before.

Storing video files.

MP4s can store video files on a wide selection of compatible devices, including smartphones, computers, and tablets. While they are smaller in size, it does not impact the quality. In fact, MP4s can preserve most of the original quality.

Video editing.

Whether for personal videos or business content, MP4 files are easy to edit, making them the ideal choice for both the video editing pro and novice.

Sharing.

Because file sizes are generally smaller on MP4s, you can easily share them with collaborators, plus they take less time to upload to selected platforms. This is particularly useful when uploading MP4 video content to streaming sites.

Pros and cons of MP4 files.

As with any file format, there are pros and cons. While MP4 files may be perfect for working across multiple platforms, they may not be suitable if you’re concerned with security issues. Find out some of the benefits and drawbacks of the MP4 file type below.

Pros.

Versatile across platforms. MP4 files are compatible with many different platforms. You can upload them to social media and internet streaming sites, then send them to your family and friends.
Store metadata. You can add metadata to an MP4 file, making it easier to search the video for important identifying information.
Compressed container file. Your MP4 files have a high amount of compression, making them a small file size still capable of holding a lot of information.

Cons.

Lossy compression. If you compress your data into an MP4 file more than once, you might experience some quality problems or lose some data due to lossy compression.
Potential security issues. Since metadata can be easily changed and deleted, MP4 files are not the most secure file choice.
Power consumption. MP4 files can use a lot of computer power because they store both audio and video. This can become a real problem if you’re working off a laptop and aren’t plugged in.

How to open an MP4 file.

Opening an MP4 file differs slightly on a Mac to a Windows PC. If you’re using a Windows operating system, you can simply head to File Explorer and right-click on your chosen MP4 file, and select the program you want to open the file in.

If you’re operating on a Mac, the process is similar. Click on your MP4 and open the file with your chosen program.

There’s a range of programs that can help you edit your MP4 files. You simply need to import your video clip into your chosen editing program, then you can use features that allow you to trim and arrange your video.

You can also edit MP4 files to apply things like text, effects, graphics, and transitions — as well as amending audio tracks and adding sound effects.
