M4B Audio Format

M4B Converter

An M4B file is also known as an MPEG-4 Audiobook file and was developed by Apple. Given its name it’s perhaps not surprising that an M4B file is commonly used for audio books. They’re used by Apple Books – specifically the audio part – and the file itself is designed to be efficient as it has been compressed using AAC encoding which means that they don’t consume much in the way of storage meaning they’re ideal for devices such as iPhones and iPads. They’re similar to an M4R file in that M4B can only be played on authorised computers to prevent piracy so often when trying to play the file users can run into problems trying to get them to play if they’ve been forwarded the file on. M4B files can be opened by Apple devices and on iTunes on either MacOS or Windows.

MP4 Video Format

MP4 Converter

MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.

MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
