I used Audio Director to reduce fan noise (it did a great job), but when it went back to Power Director, I could no longer set key frames to move the video to create some movement in an interview. Also, the clips come back into Power Director as 2 separate files, video and audio and the option to connect them is grayed out, as well as the ability to edit alias. I guess you should get your clips trimmed and do whatever else you want and THEN fix the audio?
