I shot an interview with a canon R2i 1920x1080 24p. I converted with MPEGStreamclip to ProRes HQ. I knew the file sizes would be huge, but I wasn't expected anything this big. I want the best quality I can get, but I am thinking this is over kill. Would I be better off with just using Prores or even Prores LT?
ProRes HQ is for very high end 10-bit recording formats, like AVCIntra and Red. Or things destined for film or digital projection. For DSLRs, DVCPRO HD, HDV, XDCAM...ProRes is JUST fine. ProRes LT is what I use with my T2i, as my videos are destined for the web.
