Rip-Roar Training

It's 2021, I just had the same issue. Within Video Pad, everything seemed to synch; however, when I exported it, it was not. Did it several times. One thing I noticed originally but did not take thought of was the FPS, it was higher than on other videos. I had not changed it, it was automatic. Somewhere I read, that the max FPS, for me, should be around 24, this was max at 30. So, I changed it to a max of 24 and it now is synched. I uploaded it to YouTube and it remained in synch. So, check your FPS if it is out of synch, it's an easy fix.
