So Im converting a 1920x1080 into a square of 1920x1920 and population the black space with white instead. I find that doing this is leading to an extremely large drop in quality when posting the video on instagram. Any solutions ? Im following all the so-called methods of ensuring best quality for insta like upscaling to 4k etc.
Uploading the same thing as a non-square with no white crops is definitely providing a better quality video.
