Displaying and Using SMPTE Positions
The Bar ruler of each linear editing window can independently display a SMPTE time
ruler or bar/beat ruler. For further information, see “
Adjusting the Bar Ruler Display
Choosing View > Event Position and Length in SMPTE Units in the Event List switches
the display of all positions and lengths to SMPTE times, rather than bar/beat values.
Positioning Objects to Frames (Pickup Clock)
You can use the Pickup Clock (Move Event to Playhead Position) key command to move
selected objects (an individual event, tempo event, or a region, as examples) to the
current playhead position.
To position objects to frames:
1
Set the playhead position to the required SMPTE time, by going to a specific frame of
the film in the Video track, for example.
Note: In addition to the usual position commands, you can also use the Rewind One
Frame and Forward One Frame key commands to move one frame backwards or
forwards.
2
Select the object that you want to place at this time position.
3
Use the Pickup Clock (Move Event to Playhead Position) key command to align the start
point of the object with this time position.
The Pickup Clock & Select Next Event key command selects the next object, after the
first object is moved.
Note: When using Pickup Clock with audio regions, it is the region’s anchor (not the
region start point) that is moved to the playhead position.
Fixing Objects to Frames
In situations where you’re working with synchronized film, you often want specific
sound effects to play at a specific SMPTE time, rather than a particular bar position.
If the tempo of the piece needs to be altered at a later stage, the SMPTE time location
of events that have already been positioned will change. The Lock SMPTE Position
function prevents this from happening.
You can SMPTE-lock individual events in the Event List, or entire regions (along with all
events they contain). Objects locked to a SMPTE position display a small padlock
symbol in front of their name.
