Whats New in Final Cut Pro 6: APPLE ProRes 422

Excerpted from her new DVD Tutorial ?What?s New In Final Cut Pro 6? By Diana Weynand

If youve been wanting to incorporate HD into your workflow, but didnt feel you had the storage space for it, or a fast enough computer processor, you have a new option in Final Cut Pro 6the Apple ProRes 422 codec. This new formatcreated by Appleoffers uncompressed HD quality at SD file sizes.

The purpose of this codec is simple - to create high quality images at low file sizes, which makes it ideal for post production. Both standard definition and high definition resolutions are supported at two quality levels Standard (145 megabits per second) and High (220 megabits per second). All standard frame rates are available. 

This variable bit codec provides a great way to utilize more footage without bogging down your storage resources. Right click in the Browser, and under the Item Properties window youll find all the information about your clip. 


Let's take a look at a DVCPro HD clip notice the size of this file.

Now lets take a look at a clip that was created by recompressing this DVCPro HD clip into the Apple ProRes 422 codec. Notice the file size is much smaller. 

The Apple ProRes 422 format supports full width resolution, including 1920x1080 and 1280x720; 4:2:2 chroma sampling for precise compositing, 10-bit sample depth, which preserves the subtle gradients of these sources, and I-frame-only encoding which ensures consistent quality in every frame. Because of these features, its a great format to choose when youre working with original HD footage, and you need to collaborate over an Xsan storage network, or work on a portable laptop, or when you work with non-native camera formats, and you want to preserve the quality for composites and demanding color grading work. You can also choose Apple ProRes 422 as a render option when rendering effects in HDV and XDCAM. Results yield a faster rendering time and a higher-quality 4:2:2 composite.

If you want more in-depth technical information about this new codec, you can read Apples white paper. It is available for download at this address: http://images.apple.com/finalcutstudio/resources/white_papers/L342568A_ProRes_WP.pdf
