I spent a lot of time on this 3.5 minute video on VideoPad, and I even bought the license, however, when I export the video, no matter the format, it keeps missing the same 2 parts of the video, but the audio remains. I’ve tried saving it on hard disk drive, Google Drive, but nothing happened. I even tried to re-install the program and re-enter the register code but still the same happens. Please help. Thanks
