I’m with you Jon.
Almost every day on this forum I see a post from someone asking “how do I get my HD footage to look good on an SD-DVD.” and there is usually a response from someone saying “this question gets asked all the time, but here’s a link with instructions.”
I gotta tell you that I think have tried everything that has been posted on these forums but STILL cannot get my HD footage to look decent on an SD-DVD. It ALWAYS has weird “interlacing” or “field order” artifacts. My associates tell me I am being too picky and that nobody but me will ever notice it, but it drives me crazy.
I bought Innobits Bitvice software and it dramatically reduces the amount of artifacts – but it is STILL present. I also own Video Purifier but have not yet tested it for scaling HD to SD.
