Hello. How can I add a voice comment to a video file? Some video editing program should be able do it, or is it being done after the final video clip is rendered and than imported in to a third party program that is able to bring done the videos sound volume for comments to be heard? Perhaps the voice must be recorded apart and added to the video? How can I do that? I am using video editing program but a task for me is to be able to slow own videos volume exactly in the moments when comments are starting. I am just guessing, as I am new in comments adding technique, please, any suggestion and advices are welcomed. Thanks a lot!
