Adobe Premiere CS2 has the capabilities to open and edit all types of media files, including MPEG, AVI, WMV and MOV files. At the time of CS2’s release, the MP4 format wasn’t as popular or widely used, so the software may not properly import the file. Updating your computer’s codecs, file types used to process video formats, will make the files compatible with Adobe Premiere Pro CS2. You can find codecs for all types of video and audio formats.
