I have a long sequence/video that consists of footage ripped from PAL DVDs (720x576 anamorphic 16:9 - 1024x576). I need this to be encoded into a DCP for projection in a cinema. The footage was ripped from DVD into ProRes 422, 720x576. What is the best way of ensuring the best image quality for a cinema in this case? I'm wondering about putting the file onto tape, then upscaling what's on tape via an Alechemist. Or, alternatively, upscaling the ProRes output file via an Alchemist or Teranex. But I'm also contemplating trying something crazy, like shooting a screen - playing the video - with something like a RED camera, and then blow up the RED footage into a DCP-compliant aspect.
Don't over-think the situation Paul... DVDs have been routinely used to screen movies in movie theaters for years, and the they look just fine. No matter how you slice it or dice it, a DVD is essentially what you're gonna be screening in your case, regardless of any steps you might take to try to improve the video you're ripping, and no extraordinary steps are going to polish it in any significant way, because it's already been compressed at approximately 25 to 1.
If you rip the DVD directiy to ProRes 422 you'll get video that's as good as you're gonna get.
