Editing Audio Video Interleave (section)

==Metadata==
As a derivative of the [[Resource Interchange File Format]] (RIFF), AVI files are commonly tagged with [[metadata]] in the INFO chunk. In addition, AVI files can embed [[Extensible Metadata Platform]].<ref>{{cite book|url=https://books.google.com/books?id=J8h8VWUmDuYC&pg=PA190|title=Digital Forensics with Open Source Tools|last1=Altheide|first1=Cory|last2=Carley|first2=Harvan|publisher=[[Syngress]]|date=2011|access-date=2021-09-19|page=190|isbn=978-1-59749-586-8}}</ref> By design, any RIFF file can legally include additional chunks of data, each identified by a four-character code;<ref name=Gloe-2014/> software which does not understand that particular code should skip the chunk. As such, it is theoretically possible to expand any RIFF file format, including AVI, to support almost any conceivable metadata. Some of the limitations of AVI in modern use relate to a lack of standardization in this metadata (see Limitations below).
