The output files must be flattened before they can be edited in a video editing tool such as Adobe® Premiere® Pro, or before they can be played back in Adobe® Media Player. Adobe provides a command-line flattening tool for this purpose; see http://www.adobe.com/go/learn_fmle_tools. MFVI supports decoding of flattened as well as fragmented files. Adobe Connect generates Flash media files with VP6 video codec and Nellymoser audio codec.
