10 Preface About High Definition and Broadcast Formats
Here are some advantages of using the Apple ProRes 422 codec:
 Provides lower storage costs compared to the Uncompressed 8-bit and 10-bit codecs.
 Can be used to capture using a third-party video interface with SDI or HD-SDI inputs.
 Can be used to transcode formats that Final Cut Pro does not support natively.
 Can be used to render long-GOP MPEG-2 formats (such as HDV and XDCAM HD) to
avoid MPEG-2 reencoding artifacts before output.
 The Apple ProRes 422 codec used with video processing sequence settings set for
high-precision YUV rendering can be used for preview screenings (avoiding costly
film transfers) and for color grading.
 The Apple ProRes 422 (HQ) codec can be used for output to a high-end mastering
format or even for output to film on lower-budget productions.
About the Apple Intermediate Codec
The Apple Intermediate Codec is a high-quality 8-bit 4:2:0 video codec used mainly as a
less processor-intensive way of working with long-GOP MPEG-2 footage such as HDV.
The Apple ProRes 422 Codec Works with 8-Bit and 10-Bit Source Files
The Apple ProRes 422 codec always preserves the bit depth of your original source
files. This way, when you import a file using the Apple ProRes 422 codec, you don’t
have to first determine whether it is an 8-bit or 10-bit file—the Apple ProRes 422
codec can automatically handle either bit depth.
