What isAIC

Apple Intermediate Codec (AIC) is a video codec developed by Apple Inc. primarily used for HD workflows. It is an 8-bit 4:2:0 video codec, ideal for working with long-GOP MPEG-2 material such as HDV, as it is less processor-intensive. It is recommended for use with all HD workflows in Final Cut Express, iMovie, and up to Final Cut Pro version 5.

AIC provides high performance and quality, and its decoding process is faster than other editing formats. The codec does not use temporal compression, so each frame can be decoded immediately without needing to decode other frames. However, as a result, AIC requires three to four times more storage space than HDV.

The codec is only available on the Mac OS X platform and is not currently readable on other platforms such as Windows or Linux. However, all Mac OS X software that uses the QuickTime codec libraries can use AIC. This includes Final Cut Studio, Final Cut Express, iMovie, and freeware like MPEG Streamclip.

Although AIC was commonly used in the iLife package, especially in iMovie, it is now rarely used in Final Cut Pro version 6. The ProRes codecs are now preferred over the Apple Intermediate codec. However, some versions of Final Cut Pro (HD 4.5 to 5) and Final Cut Express still make use of AIC regularly.
