I have clips of some DSLR video I shot. I opened them in MPEG stream and exported them as Apple AIC in a MOV container. The clips were 1280x720 and 1920x1080 and ultimately the quality I could care less about...AIC 1080p seams to be 1440x1080p @ 16:9 (using non square pixels)...I stated I did NOT care about quality but will this hamper the quality? MPEG stream clip transcoded FAST and when I imported the clumped together clips in the giant MOV container in AIC format FCP X seams to accept it MUCH faster than if I transcoded in FCP X using ProRes, Uncompressed 8bit, etc. When I went to click transcode media it only gave me the option of using proxy media not optimized...does this mean I really don't have to transcode, and that FCP X only needs to make the thumbnails for the timeline? Thanks in advance. tldr; Is Apple Intermediate Codec a decent choice over ProRes when editing with FCP X if AIC is faster to transcode than others?
