Apple Final Cut Pro 7 - Manual (Page 1475)

• Your computer has enough processing power to handle the real-time playback of both
the clip and sequence formats. For example, if you are using a portable computer, you
won’t be able to play back uncompressed video.
Formats That Support Real-Time Playback
For a list of formats supported by Final Cut Pro real-time processing, see the Effect Handling
tab in the System Settings window or check the list of Easy Setups included with
Final Cut Pro. For more information, see
“Supported Real-Time Playback Codecs” and
“Audio/Video Settings and Easy Setups.”
Media with codecs, frame rates, or image dimensions not supported by real-time
processing in Final Cut Pro, such as MPEG-4 or H.264 media, must be rendered before it
will play back.
Viewing Clip Properties and Sequence Settings
You can quickly check clip properties and sequence settings to see if the format of a clip
and a sequence match.
To view the current format properties of clip
Do one of the following:
µ
Select a clip, then choose Edit > Item Properties > Format (or press Command-9).
µ
Look at the appropriate Browser columns. For more information on working with Browser
columns, see
“Browser Basics.”

The following clip properties and sequence settings are relevant when working with
mixed formats. If any of the clip properties don’t match the corresponding sequence
settings, your sequence is a mixed-format sequence.
