After working well for many videos l have made, the audio on my videos suddenly became distorted using my Movie Edit Pro Premium. I am uploading a copy of a distorted file.
Try going to the program settings under File/ Settings/ Program/ and in the Playback tab increase the multi-track and preview sizes but leave the buffer amounts alone to begin with. if you are not running that many audio tracks 32768 samples should do it. Just keep pressing the + button for each one until you get there.
