I keep my old SD scenes at the original 720x480 on my pay site. But I convert them to 1080P HD for PornHub and other sites like ManyVids and Clips4Sale and they do sell. It helps a lot if you letter box them rather than stretch to fit the screen. I use Vegas Pro 17 to enhance the color and sound and then render to MP4. They were all shot on Mini DV's and captured in raw AVI. Here's a sample:
