We have a problem with the watermark upon ffmpeg conversion to .mp4. If input video is in smaller resolution then watermark appearing in the output is too big, so video won't properly resize (upscale). We need a proper command that will upscale video resolution if this is smaller than 720px (width). Resizing bigger videos work fine, but not smaller. So, we would always like 720px-1(dynamic height), no matter what is the input video resolution. I need somebody experience to edit the following ffmpeg execution code for us. Thank you!
