using industry tools on a lossless master will produce a much better image than a TV scaler working with a compressed file. I've upscaled
a number of SD projects to HD for broadcast using InstantHD, and it can work pretty well. Obviously it doesn't create data, but it's pretty
clever. For fun, here's a different upscaled version. I degrained it, uprezzed it (with too much sharpening), put the grain back in, and then,
unfortunately, re-compressed it to a jpg.
Because of prior compression artifacts, there is still some grunge on the dish as well as some stepping. I wish the X0 guys would post
some native rez PNGs for us to play with.
