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.<br><br>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.

AC3 Audio Format

AC3 Converter

The AC3 (Audio Codec 3) file format was developed by Dolby Laboratories, and is an audio format designed to support surround sound. The format can include up to six separate channels of audio output - one for each of the five speakers in a surround sound setup, plus one for a subwoofer. AC3 files use Dolby Digital lossy compression technology, which maintains sound quality even with a reduced file size.<br><br>Although this file format was originally developed for audio in cinemas, it now has many other uses, such as in digital video streaming and TV broadcasting, for DVD and Blu-ray discs, and for video game consoles. The format’s reduced file size makes it ideal for storing and distributing - e.g. on a DVD or Blu-ray disc. An AC3 file can be opened by many different media players, including Apple QuickTime, Windows Media Player, and VLC.
