I just recorded a 20 minute video that plays perfectly on my computer, but has no sound uploaded to YouTube. https://youtu.be/-nYUQWnWaS0. I can't seem to attach the mp4 file, but I'll try to attach it in the comments.
This may have something to do with settings, as I just downloaded and set up the latest version of Bandicam because the old version started hanging in the middle of my recordings. I thought I followed instructions for the settings, but who knows.
I don't want to re-record this video. I either want to fix it on YouTube, something I suspect is impossible, or figure out how to re-load the entire thing, video + audio up to YouTube.
