ProRes 422 is a standard-definition and high-definition lossy video compression format developed by Apple Inc. for use in post production. It was introduced in 2007 with Final Cut Studio 2  and is comparable to Avid’s DNxHD codec which has the same purpose and uses similar bit rates. Both are DCT based intra-frame-only codecs, and are therefore simpler to decode than distribution oriented formats like H.264.

PS: While Final Cut does not edit AVCHD natively, it is still a simple procedure to utilize the AVCHD footage. In Final Cut you would open your log and transfer window and import the footage as Pro Res 422 which, while it creates larger files, is a great codec to edit with and I do so with most everything.I suggest you purchsed  Pavtube AVCHD Convert for Mac, because compressor is very slow and Final Cut handle AVCHD files when it finds them in their original file structure (either by connecting the camcorder or using a memory card reader), not isolated .mts files.You don’t need the biggest and best Mac Pro and just either Final Cut Studio 2 or 3 will do just fine. I would suggest having a minimum of 4 gigs of ram which is the most FCP can utilize anyway at this point.
