Definitely consult with your lab as Todd suggests – unfortunately going to hard drives does not always equal savings – if the lab would spend 1 hour with your footage on the telecine, laying off to an HD/SD tape in real-time, going to a drive might take the same hour on the same telecine, plus putting your media on their storage, plus encoding it to your requested format, plus transferring it to your drive… only they will be able to tell you for sure, as some labs have worked out better ways than that…
If you don’t have regular access to a deck (of the format you want) it can definitely help there. ProRes 422HQ or ProRes4444 are codecs that are of a pretty high quality, and at 1080 24p can usually be played back in real-time on a desktop or good laptop. They strike a good balance between quality and lightweight-ness, especially if the project won’t be traditionally on-lined… I like to keep a ProRes422HQ file of my finished products for reels and the like.
DPX files are larger, and since most people using them are using them as the basis for a digital intermediate at 2K/4K resolution, I think labs are more used to passing along a “flat” pass of some kind – so you would get a file that is too large to edit with, and doesn’t resemble the intended look. But if you are comfortable doing a rough color correct and creating offline media with identical timecode to the DPX files, and will be at some point going back to the DPX in a traditional on-line… they’re definitely high-quality. Keep in mind that at 12MB or so per frame, having drive space and a backup can be expensive…
