My Movie Studio Platinum 13 used to work fine. I had to reinstall Windows 10 and start my machine again. I reinstalled Movie Studio and everything seems right. However, when I put a music track on the music track, I notice that the sound waves look awful! There is no longer one long music wave moving up and down, but rather there are suddenly two waves one on top of the other. When it plays, the Db shoots to the highest level breaking through it completely and the music sounds like the noise made when one used to play a tape cassette and press the fast-forward button at the same time. It's just like a whistle sound moving through the entire track - going up and down - as if the music is playing at about ten times the actual speed (but really it's not, because the track is still as long as it should be.)
My ordinary video file works fine and a video with me talking works fine with the sound working as it should. It is just when I add the music track that this music track does this. If I play the file as an ordinary mp3 using mp3 software, the file plays just fine.
Can anyone help me to solve this problem? Theoretically, I'm no longer able to use the Movie Platinum software if I can't get this right - even though at one stage (before I reinstalled Windows) it worked fine.
You can see a screenshot of the music track spanning just 5 seconds and how the music is clearly distorted. I cannot get it to play correctly. https://screenshot.net/jded1to
I'm using Movie Studio Platinum 13 Build 987 64 bit.
Any help would be appreciated - thank you.
