Apologies if this topic has been covered before. New user. I just purchased movie studio 17 and my first 2 multi track editing efforts (backing track & Vocal) imported from OBS went swimmingly. Every recording since has had issues when I import the remux mp4 file from OBS. My vocal sounds like it's dropped (slowed down) by a tone, but the backing track is fine. I'm sure I read it's to do with the sample rate? but I'm not sure at all what I've done!. I have it set currently at 44,100kHz on both OBS and Movie Studio. I'm running Windows 10. I'm a bit of a novice at this, but if anyone can help, it would be greatly received.
