There are a great many file formats available for media, though the industry tends to use just a few regularly. This video explains exactly what a file format is, and how the concept of a file format—or file type—differs from the concept of a media format. Understanding the difference between a codec, format, and file type can help you make important choices about your media acquisition and delivery.
- [Instructor] It's easy to confuse…codecs, formats, and file types.…And I'd like to take a moment to clarify…the differences between them.…Now let's start with the codec.…This is the actual video and sound information…in your media file.…There are lots of different codecs available…and there are wonderful debates to be had…about the best codec for a particular purpose,…but whichever you choose, this is the actual media.…That media stored as a codec will be inside a file type.…This might be a Quicktime movie, AVI file, or whatever.…
These are often referred to as formats,…but it's really just a type of file.…There are several different popular media file types,…each developed by different companies,…often for different purposes.…Perhaps one is developed for camera acquisition…while another is for archiving…or media exchange between software applications.…All media files serve in particular ways.…They can contain particular codecs,…and by this I mean that not every codec…can be contained by every media file.….MOV Quicktime movie files are particularly flexible…
