    I usually transcode my footage from Sony NX5U to ProRes in Final Cut Pro. I shoot 1080/30p and transcode to the same ProRes equivalent.

    I have a friend I shot footage for and he asked me to give it to him in Apple Intermediate Codec (AIC). When I went to select the 'output' in Final Cut Pro, the only choices for AIC were:

    720p 1280 x 720 29.97 fps Progressive
    1080i 1440 x 1080 25 and 29.97 fps Interlaced
    1080p 1440 x 1080 23.98, 25, and 29.97 fps Progressive

    What's the deal? Where is 1920 x 1080, 29.97 fps w/ Progressive at?

    AIC is very limited. It was originally created to deal with HDV, for which high definition is 1440 x 1080 and it is flagged in the NLE to be anamorphic (i.e. non-square pixels) to it is "stretched" to 1920 x 1080.

    Apple's info.

    As a codec it holds up OK for simple editing workflows, but, being 8-bit 4:2:0 colour, the professionals turn up their nose at it.

    Find out what platform your friend is editing on. The only reason he should ask for AIC is if he's using iMovie or FCE to edit, or a version of FCP older than 6.0. Otherwise, there's no reason not to use ProRes.

    Another thing you can try (although I can't attest to the results) is duplicating one of the AIC presets in FCP and customizing it for your video's parameters. I would imagine that you should be able to force a 1920x1080 frame with square pixels and a 30p frame rate. I'm just not sure what the field dominance setting (if any) would be for your camera. You'll want to investigate that.
