D3 is never going to look amazing scaled upto HD. Its a composite format, so your going to get all that nasty chroma noise etc... In terms of capturing the file you are just going to need a good quality component video to SDI converter. I'd get the post house to transfer it as a SD ProRes HQ, 4:4:4 ideally, but 4:2:2 would also be fine since component has terrible colour to start with (you won't loose anything by going 4:2:2) I wouldn't get it upscaled to HD during the transfer, that would be expensive and there are better solutions then a terranex or snell and Wilcox real time converter. As you noted scaling the image in Resolve isn't going to give amazing results because the source material is poor. Ideally you are going to need to us an AI up-converter like the Topaz labs one. The results can be magical, but be prepared for some very long render times. It will never look like proper HD, but if it's really well shot it might look ok....something you'd need to test. https://www.topazlabs.com/topaz-video-ai
