Encoding and compression options for moviesCompression is essential for reducing the size of movies so that they can be stored, transmitted, and played back effectively. Compression is achieved by an encoder; decompression is achieved by a decoder. Encoders and decoders are known by the common term codec.No single codec or set of settings is best for all situations. For example, the best codec for compressing cartoon animation is generally not efficient for compressing live-action video. Similarly, the best codec for playback over a slow network connection is generally not the best codec for an intermediate stage in a production workflow. For information on planning your work with final output in mind, see Planning your work. After Effects uses an embedded version of the Adobe Media Encoder to encode most movie formats through the Render Queue panel. When you manage render and export operations with the Render Queue panel, the embedded version of the Adobe Media Encoder is called automatically. The Adobe Media Encoder appears only in the form of the export settings dialog boxes with which you specify some encoding and output settings. Important: The embedded version of the Adobe Media
Encoder used to manage export settings within After Effects output
modules does not provide all of the features of the full, stand-alone
Adobe Media Encoder application. For information about the full,
stand-alone Adobe Media Encoder application, see Adobe Media Encoder
Help.
You can also use commands in the File > Export menu to encode movies into some formats (such as raw DV streams) using QuickTime components. (See Rendering and exporting movies using QuickTime components.) For most output formats, you can specify format-specific encoding and compression options. In many cases, a dialog box opens and presents these options when you choose a format to export to or click the Format Options button in the Output Module settings dialog box. (See Output modules and output module settings.)
