AAF file format
AAF is a file format created by the Advanced Media Workflow Association (AMWA) as a standard for storing the resultant product of post-production activities peculiar to film and video editing. AAF is an offline equivalent of the EDL multimedia format, which implies a form that saves the video file's edit history before the final encoding is effected. Being a format that can be used across different video editing software platforms, many creators of video production technology have designed their software to support the AAF file format. The average .aff file contains data representing source file elements, metadata, program content, and edit history, copies of remote online content, relevant media effects, and HTML/XML.
The AAF was created as a solution to the incompatibility being experienced across different video creation technology platforms. As declared to be the perfect video analogy of word processing, AAF has come to be accepted across various multimedia production platforms. Due to the complexity of multimedia files and shear variations in their content properties, constituent data like audio, video, image, graphics, and animation are often rendered in different formats. But AAF eliminates this bottleneck by allowing all the media data. The code that specifies how they are to be superimposed to make comprehensive multimedia will be encoded into a singular document.
