[Update on Incorrect Pitch]: An investigation found that the frame rate was exported too low, causing the lower pitch. The video editing software has limitations on the frame rates we are allowed to be exported. We managed some sort of a fix for future videos for now, but perhaps when we manage to afford to acquire an Adobe Premiere Pro license that would a long-term solution. Thank you for your patience!
