From the Adobe Audition CS6 manual:
Video import formats
The Waveform Editor lets you open the audio portion of video files in the formats below. The Multitrack Editor lets you insert the same file types and provides a preview in the Video panel.
To access these video formats, QuickTime must be installed. To import additional formats, extend QuickTime support. For more information, see this article on the Apple website. http://www.adobe.com/go/learn_audition_qtformats_en
AVI
DV
MOV (including files with up to 32 audio channels)
MPEG-1
MPEG-4
3GPP and 3GPP2
First of all, that link is long broken. The above is a mixture of containers and compression formats. AVI is a container, but there is no list of what codecs that can be in that container. The same with MOV. What formats can the MOV container have?
