Determining Whether Clips in a Sequence Will Play Back in Real Time

When a sequence contains a clip whose media file format doesn’t match the sequence format, the clip plays back in real time only if:

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:
  • Select a clip, then choose Edit > Item Properties > Format (or press Command-9).

  • Look at the appropriate Browser columns. For more information on working with Browser columns, see Browser Basics.

To view the current sequence settings
  • 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.
