Edit event properties

Use Event Properties to edit settings for events on the timeline.

Use Media Properties to view or edit the source media. The dialogs serve different purposes.

Edit the name of the active take

If you recorded multiple takes, edit their names in the Properties dialog.

1. Right-click the event and choose Event Properties from the shortcut menu.

2. On the Audio Event tab, enter or edit the take name in the Active take name box.

3. Click OK.

Change event switches

1. Right-click the event and choose Event Properties from the shortcut menu.

2. On the Audio Event or Video Event tab, select the switches you want to use.

Time-stretch or pitch-shift an audio event

NOTE The Resample and stretch quality setting on the Audio tab of the Project Properties dialog controls audio time-stretching quality. »For further information: Setting project properties

Edit from the timeline

1. Select an event.

2. Use the = and - keys on your keyboard (not the numeric keypad) to adjust pitch:

   Key	Result
   =	Raise pitch one semitone.
   Ctrl+=	Raise pitch one cent.
   Shift+=	Raise pitch one octave.
   Ctrl+Shift+=	Reset pitch.
   -	Lower pitch one semitone.
   Ctrl+-	Lower pitch one cent.
   Shift+-	Lower pitch one octave.
   Ctrl+Shift+-	Reset pitch.

If Active Take Information is selected from the View menu, the event's pitch shift is displayed in the bottom-left corner of the event. If the media has a known root note, the new root is displayed in parentheses.

Edit time-stretch settings in the Properties dialog

1. Right-click the event and choose Event Properties from the shortcut menu.

2. On the Audio Event tab, choose a setting from the Method drop-down list.

   Setting	Description
   None	Turns off time stretching and pitch shifting.
   ėlastique	The élastique method uses technology from zplane.development, and provides enhanced real-time time stretching and pitch-shifting capabilities. The élastique method also allows you to preserve and shift a clip's formants, which are the characteristic resonant frequencies of a sound. Choose a setting from the Stretch attributes drop-down list to choose the stretching method best suited to your media: Pro – Provides the highest quality stretching but requires more RAM usage and CPU power. Efficient – Uses fewer resources while still producing great time-stretching quality for polyphonic audio. Soloist (Monophonic) or Soloist (Speech) – Provide good quality for monophonic audio with little effect on system resources. Type the desired event length in the New length box. The event's original length is displayed for reference in the Original length box. Type the desired pitch shift (in semitones) in the Pitch change box. To change the event length without changing pitch, type 0 in the box. To link the pitch to the new event tempo, select the Lock to stretch box. For example, doubling an event's tempo will raise its pitch by one octave. When élastique Pro is selected in the Stretch attributes drop-down list, type a value in the Formant shift box to adjust the event's formants. This option is only available when the Preserve formants checkbox is selected. Formant shifting can be used to deepen the tone of a vocal performance without changing the pitch. The formant shift amount represents the number of semitones to Shift the timbre in addition to the offset required to compensate for any pitch shifting. For example, a setting of 0.000 applies formant correction with no additional shifting, while a setting of -7.000 will apply formant correction and deepen a sound by 7 semitones.
   Classic	Allows you to time stretch the audio by specifying a new event length. Specify a pitch shift amount or lock the pitch to the time stretching. Type the desired event length in the New length box. Type the desired pitch shift (in semitones) in the Pitch change box. To change the event length without changing pitch, type 0 in the box. To link the pitch to the time stretch, select the Lock to stretch box. For example, doubling an event's length will raise its pitch by one octave. Choose a setting from the Stretch Attributes drop-down list to specify how you want to divide and crossfade the file to prevent artifacts. Depending on your source material, you may need to experiment with different crossfade types.

Change the playback rate or undersample a video event

1. Right-click the event and choose Event Properties from the shortcut menu.

2. On the Video Event tab, adjust the Playback rate and Undersample rate controls.

   Setting	Description
   Playback rate	Enter a value in the box to set the rate of playback. For example, a setting of 1 will play at normal speed, while 0.5 will play at half speed. Each video event in your project has a specific duration that is not changed by adjusting the playback rate. If you decrease the speed of a ten-second video event by 50%, only five seconds of video will be shown. On the other hand, if the speed is increased 200%, the ten seconds of video will play in only five seconds. The remaining five seconds of the event will be filled either with a freeze of the last frame or with ten additional seconds of video content from the media file (if the source media is longer than the event).
   Use Project Resample Mode	Applies the resampling mode selected in Project Properties.
   Frame Blend	Blends adjacent frames when resampling.
   Optical Flow	Uses optical-flow processing instead of frame blending when resampling.
   Disable resample	Disables resampling for the event.
   Conform to Project Frame Rate	Click to adjust the playback rate of a high-frame-rate clip to play using the project frame rate. »For further information: Working with high-frame-rate (HFR) clips
   Undersample rate	Enter a value in the box to simulate a lower frame rate. For example, if you enter 0.5 in the box, the event will play at half its original frame rate, and each frame will be held twice as long as in the original media file, creating a strobe effect.
