Apple 'None' Codec



General Information
Overview
The None codec doesn't actually compress. As such, it is lossless and produces huge files. It is often used as a storage format for files that need to be archived with perfect quality, as well as an intermediate format for files that need to have effects applied to them multiple times.
Architectures Supported
Pros, Cons & Tips
Pros
  • Lossless

Cons
  • The None codec produces huge files.
  • Movies using the None codec normally won't play smoothly given their high data rates.
  • The Animation codec is usually a better storage format given its smaller file sizes.

Tips
  • When converting full-color data to indexed colors (256 colors or less) using the None codec, the Quality setting affects how the codec does the conversion. If the Quality setting is set to Most, you'll get a dithered image. If the Quality setting is set to Least, you'll get a posterized image.
