106 Chapter 7: Formats Using the Flatten Only Setting To create a flattened copy of a movie, process the movie with the preconfigured Flatten Only setting in the QuickTime folder just as you would process any movie with any other setting. If you choose this option, Cleaner flattens the movie without re-encoding it and puts a flattened copy in the destination for that item. To create your own setting to only flatten a movie, check the Flatten Only option in the Tracks tab. This enables you, for example, to assign alternate movie criteria to movies that are already encoded without having to re-encode them. For more details, please see "Making Alternates from Encoded Movies" on page 116. QuickTime Codecs The QuickTime file format is an open standard with many built-in codecs. There are also additional codecs available from third parties, such as Sorenson Video codec Developer Edition. There are essentially two types of QuickTime codecs. Authoring codecs (for example M-JPEG, Photo-JPEG) - used during capturing and editing and not used for actually distributing content to viewers. Authoring codecs are used for "intermediate" production and storage. Delivery codecs (for example Sorenson, MPEG-4, AAC) - used for presenting movies to viewers. Do not reprocess files encoded with a delivery codec, because this decreases quality. Capture and Author Codecs When capturing video, use the codec specified in your capture system documentation. During editing and effects, use your specific capture system codec. For truly lossless production, such as rendering After Effects projects, use the Animation codec at 100% quality. If you do not have a dedicated capture system with its own codec, use the Photo-JPEG codec at a high-quality setting. This produces smaller files than the Animation codec and is close to lossless. You can also use M-JPEG (either A or B) for full-frame interlaced material. Web Codecs For progressive or realtime-streaming delivery over a network, use Sorenson Video 3 or MPEG-4. For Web audio, use MP3 or AAC for music and mixed audio. Note: MPEG-4 and AAC are compatible only with QuickTime 6 or higher.

Using the Flatten Only Setting
To create a flattened copy of a movie, process the movie with the preconfigured Flatten Only
setting in the QuickTime folder just as you would process any movie with any other setting. If
you choose this option, Cleaner flattens the movie without re-encoding it and puts a flattened
copy in the destination for that item.
To create your own setting to only flatten a movie, check the Flatten Only option in the Tracks
tab. This enables you, for example, to assign alternate movie criteria to movies that are already
encoded without having to re-encode them.
For more details, please see “Making Alternates from Encoded Movies” on page 116.
QuickTime Codecs
The QuickTime file format is an open standard with many built-in codecs. There are also
additional codecs available from third parties, such as Sorenson Video codec Developer
Edition. There are essentially two types of QuickTime codecs.
Authoring codecs (for example M-JPEG, Photo-JPEG) — used during capturing and editing
and not used for actually distributing content to viewers. Authoring codecs are used for
“intermediate” production and storage.
Delivery codecs (for example Sorenson, MPEG-4, AAC) — used for presenting movies to
viewers. Do not reprocess files encoded with a delivery codec, because this decreases quality.
Capture and Author Codecs
When capturing video, use the codec specified in your capture system documentation.
During editing and effects, use your specific capture system codec. For truly lossless
production, such as rendering After Effects projects, use the Animation codec at 100% quality.
If you do not have a dedicated capture system with its own codec, use the Photo-JPEG codec at
a high-quality setting. This produces smaller files than the Animation codec and is close to
lossless. You can also use M-JPEG (either A or B) for full-frame interlaced material.
Web Codecs
For progressive or realtime-streaming delivery over a network, use Sorenson Video 3 or
MPEG-4.
For Web audio, use MP3 or AAC for music and mixed audio.
Note:
MPEG-4 and AAC are compatible only with QuickTime 6 or higher.
