What is an MP4 (MPEG-4) file?

MPEG-4 (MP4) is a container video format that can store multimedia data, usually audio and video. It is compatible with a wide range of devices and operating systems, using a codec to compress file size, resulting in a file that is easy to manage and store. It is also a popular video format for streaming over the Internet, such as on YouTube. Many consider MP4 to be one of the best video formats available today.

How to open an MP4 file?

MP4 files open in the operating system's default video player. Simply double-clicking the file opens it. There is no need for third-party software. On Windows, it opens in Windows Media Player. On Mac, it opens in QuickTime.

On some devices, particularly mobile, opening this file type can be problematic. MP4 is a container that contains various kinds of data, so when there is a problem opening the file, it usually means that data in the container (an audio or video codec) is not compatible with the device’s OS. To resolve this issue, try VLC media player.

What is an AIFF (Audio Interchange File Format) file?

Apple developed Audio Interchange File Format (AIFF) to store high-quality, digital-audio (waveform) data. Many professionals use it, particularly users of Apple platforms. It is lossless, which means there is no loss of quality or data from the original, but this also means that AIFF files take up more space. AIFF can locate loop point data and musical notes, which is useful for musicians.

How to open an AIFF file?

By default, AIFF opens in Windows Media Player or iTunes, depending on the operating system. Other programs that open AIFF include VLC media player, Audacity, Winamp, and Elmedia Player.

Please note that if using an Android or non-Apple device, you will need to convert the AIFF file—likely to a MP3 file—in order to open it. Mobile Apple products open AIFF files without file conversion.
