Well, I do get myself in a pickle . . .
I needed to have some work done on the audio, and I didn't know that this person who changed my voice on my slideshow would send it back to me in another format. It is now a movie in .mp4. Problem is, I hadn't completed working on it in PhotoStage. In fact, the man told me to take out all background music, etc. so it would not interfere with the voice audio. At his suggestion I downloaded another piece of complicated software, but I don't want to learn another software when I am completely satisfied with PhotoStage.
Any suggestions?
