prores was never that common on consumer cameras other than blackmagic. even on sony cameras, you have to pay for that option. it's an expensive codec because of apple. so i don't understand all of the sudden this requests for prores raw. it only works with final cut at the moment and if you don't have prores, most likely you're not going to get prores raw. that's why you see proprietary codecs, xavc, avc, canon xf avc, etc
