Apple ProRes File Format

What is Apple ProRes?
Apple ProRes is a lossy video compression format for use in post production that supports up to 4k. It is the successor of the Apple Intermediate Codec and was introduced with Final Cut Studio 2 by Apple Inc. It is a kind codec, visually lossless across many generations.

Review of Apple ProRes
Apple ProRes 422:
This codec offers nearly all the benefits of Apple ProRes 422 (HQ), but at 66 percent of the data rate for even better multistream, real-time editing performance. Apple ProRes 422(.mov)" is the best format, if you prefer smaller file size, choose "Apple ProRes 422(LT) (.mov)" instead.

Apple ProRes 422 (HQ):
The Apple ProRes 422 (HQ) codec offers the utmost possible quality for 4:2:2 or 4:2:0 sources (without an alpha channel). It has higher quality than Apple ProRes 422 and target data rate of approximately 220 Mbps (1920 x 1080 at 60i).

Apple ProRes 422 (LT):
With a target data rate that is roughly 70 percent of the data rate of Apple ProRes 422 and 30 percent smaller file sizes than Apple ProRes 422, this codec is perfect for environments where storage capacity and bandwidth are at a premium.

Apple ProRes 422 (Proxy):
This codec is intended for use in offline workflows that require low data rates but full-resolution video. The target data rate is roughly 30 percent of the data rate of Apple ProRes 422.

Apple ProRes 4444:
This codec offers the best quality for 4:4:4:4 sources and for workflows involving alpha channels.
1: Direct encoding of, and decoding to, both RGB and Y′CbCr pixel formats
2: Mathematically lossless alpha channel (up to 16 bits) with real-time playback
3: High-quality solution for storing and exchanging motion graphics and composites
4: Support for any resolution, including SD, HD, 2K, 4K, and other resolutions
5: A remarkably low data rate compared to uncompressed 4:4:4 HD (the target data rate is approximately 330 Mbps for 4:4:4 sources at 1920 x 1080 and 29.97 fps)
6: Full-resolution, mastering-quality 4:4:4:4 RGBA color, perceptually indistinguishable from the original material with excellent multigeneration performance
7: A Gamma Correction setting in the codec’s advanced compression settings pane, which is also available with the Apple ProRes 422 codec.

Compare with Other Codec
Recording to Apple ProRes preserves the quality of the video much better than recording to one of the consumer "delivery" codecs like AVCHD, MJPEG or Long-GOP MPEG-2. These codecs, which are the ones that DSLRs and Pro Video Cameras normally record to, are designed to package video so that it occupies very little space. Their priority is low bit-rate rather than quality.
