Really appreciate the feedback. One question though so I understand correctly.
It was suggested to use a cropped overlay. Does FFMpeg auto scale up then? I need overlay content on all four corners of the video. What I did was create on png that is the same size as the video source resolution. If I crop everything out but the text I need, then FFMpeg, by default, will stretch that to the corners of the video? I had not read that anywhere so I was just wanting to make sure that I understood correctly. Again, thank you for your help here.
