dialog, and so on. The range bar for the Scene
even t represents which portion of the scene is
selected. If the range covers Video Post f rames
25 to 35, executing the queue renders scene
frames 25 to 35. Moving the range bar for the
scene is like mov ing a t ime window within the
scene.
To offs et the s cene in time:

number where playback begins. If Scene Start is
0, frame 0 of the scene is the first frame played
back; if Scene Star t is 12, f rame 12 is the first
frame to play, and so on.
The range bar length determines how many
frames of the scene to play. Dragging the end
point of the range bar changes the length of
the playback range. Although Scene End is
unavailable, its value updates to show the frame
number of the last scene frame that wil l be
played.
Dragging the range bar changes where the scene
is played within the final video. For example,
if you set Scene Start to 5 and move the range
bar to beg in at Video Post frame 20, frame 5 is
played at frame 20 of the final video, and so on.
To off set the s cene a nd change scene pl ay back r ate:
• Turn off Lock Range Bar to Scene R ange.

V ideo P ost frames as there are corresponding
scene frames, then playback is at the scene’s
playback rate. If the range bar specifies
fewer frames, the scene is sped up. If the
rangebarspecifiesmoreframes,thesceneis
slowed down. When it executes, Video Post
automatically skips frames or adds frames to
control the speed of scene playback.
Forexample,ifSceneStartisframe5andScene

frames overall. If the range bar covers only 10
Video Post frames, scene playback is sped up to

other hand, the range bar covers 120 frames,
scene playback is stretched to slow it dow n.
