Transcoding to AIC in Final Cut Pro
on Apr 22, 2011 at 4:52:25 am

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 Log and Transfer, 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?

Apple Intermediate Codec is an OLD codec. And it is anamorphic at 1080i and 1080p...meaning not FULL raster 1920x1080, but rather 1440x1080. If they want AIC, then you need to give them it at 1440x1080.

Thanks to both of you for your responses.

What is disturbing me is that iMovie '09 allows me to transcode the AVCHD using it's "full import" option. It's disturbing because it sounds as though AIC doesn't even support 1920x1080/30p format. I've done many projects using iMovie '09 and output them at the aforementioned output thinking I was getting 1920x1080/30p format. It bugs me that iMovie '09 has probably been stretching out the 1440x1080.

If you've done many projects and never noticed the difference then what's the big deal?

@ David - I understand the point your are making with your statement.

However, I feel it is wrong on Apple's part to mislead consumers. Let me give you a comparable situation. When shopping for diamonds, one cannot normally distinguish the difference in clarity, color (cut & carat should be easy to see). We rely on the appraisal and certification to be accurate. Apple's 'full import' should live up to the same standard. Why does it matter? When I wrote contracts for some of my projects, I told my client that I record in 1920x1080 and provide the same in the final format.

And, unless you specified that you were delivering square pixels your contracts are just fine.

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.

Still if that's what he wants/needs, then that's what he'll get.
