Important: If you are using retiming controls on a setting using the QuickTime Movie

output format and choose “Pass-through” for the audio setting, the audio does not have

its speed changed and will not maintain sync with the video. See About the QuickTime

Movie Encoder Pane for more information.

Converting Video to a New Speed

The retiming controls give you three options for determining the playback speed.

You can determine the playback speed of the output media file by:

• Entering a percentage

• Entering a duration

• Forcing the frames to play at the Encoder pane’s Frame Rate setting

Entering a Percentage

You have two options when using the percentage method to determine the clip’s duration:

• Entering a percentage value

• Choosing a preset value

The presets that you choose from are intended to be used for specific situations.

• 24 @ 25: Use this setting when you have 24 fps video that you want to convert to 25 fps

for PAL distribution.

• 23.98 @ 24: Use this setting when you have 23.98 fps video and want to convert it to

24 fps.

• 23.98 @ 25: Use this setting when you have 23.98 fps video and want to convert it to

25 fps for PAL distribution.

• 30 @ 29.97: Use this setting when you have 30 fps video and want to convert it to

29.97 fps.

• 29.97 @ 30: Use this setting when you have 29.97 fps video and want to convert it to

30 fps.
