I am here to drop the frivolous opinion that stretching 4:3 images and video to 16:9 is wrong and hurtful. Empty black borders are good and fine. If your audience complains, explain the virtues of seeing art as it was originally intended. If the point is made that we should then be watching the content on old CRT televisions if that’s the issue, tell them that’s not the issue, it’s that stretching 4:3 images to 16:9 looks bad, and should be discouraged, amen.
