Formats That Don’t Support Real-Time Playback
Media with codecs, frame rates, or image dimensions not supported by the real-time
processing engine 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:
m Select a clip, then choose Edit > Item Properties > Format (or press Command-9).
m Look at the appropriate Browser columns. For more information on working with
Browser columns, see Volume I, Chapter 5, “Browser Basics.”
To view the current sequence settings:
m Select a sequence, then choose Sequence > Settings (or press Command-0).
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.
