I recently switched from Windows to a MacBook Air M1 2020 model and have been using OBS Studio to record screen lectures. However, when I uploaded the videos to Udemy, I noticed that they were getting vertically shrunk. I researched the issue and discovered that Mac has a resolution of 16:10, but Udemy converts it to 16:9. Although I tried to rescale the video in OBS, the bottom section of the video is not visible as it goes out of the screen canvas. When I tried using a 16:10 aspect ratio for my videos, they did not look good when uploaded to Udemy.
I have been struggling with this issue for a long time, and I would appreciate any advice or recommended recording settings to solve this problem.
