SFM/Manipulating shots

Each shot is an individual entity, almost like a separate file. It has a head (its in point) and a tail (its out point). An edit point is the transition between two shots—where the tail of shot A meets the head of shot B. You can copy, paste, and delete shots.

You can think of shots as containers that don't necessarily display all their contents. For example, when you blade a shot, the container you see on the timeline is shorter than the original shot was, but it still contains all the media of the original shot: its motion data, sounds, effects, particle systems, and so on. You can change what part of the media a shot displays without changing its duration.

Retiming shots

After you've created shots, you can affect their timing in a number of ways:

• Location—You can adjust a shot's location on the timeline, either by changing the order of your shots, or by moving a shot earlier or later relative to its adjacent shots.
• Duration—You can adjust the duration of a shot, and you can control whether that change affects the frames at its head or at its tail.
• Time window—You can adjust a shot's time window: which part of its contents it displays. For example, if the original shot was 30 seconds long, you can modify a shot bladed from it to display 12 seconds at the beginning, 18 seconds in the middle, 40 seconds that include only 15 seconds of the original shot, and so on.
• Scale—You can adjust a shot's time scale to stretch it (make it slow-motion) or compress it (make it fast-motion), with or without affecting its duration.

You can also control how retiming one shot affects the locations, durations, time windows, and scales of other shots.

The kind of modification you make depends on whether you're dragging a shot's head, tail, or center, or the edit point between two shots. The lower-left corner of the SFM displays tooltips as you hover over shots, their heads and tails, and their edit points, and the tooltips change when you hold down the hotkey(s) Ctrl, Alt, and ⇧ Shift:

• Stick—Preserve the head or tail that you're dragging. Any changes are applied to the other edge of the shot. The opposite of roll.
• Roll—Modify the head or tail that you're dragging. The other edge of the shot is preserved. The opposite of stick.
• Ripple—Modify a shot's duration, and adjust the rest of the shots in the sequence to compensate.

Modifying shots

Move the playhead between shots	Press Up or Down
Set the head of a shot to the playhead's location	Press I
Set the tail of a shot to the playhead's location	Press O
Restore a shot's original time scale	Right-click the shot, click Edit Clip, click Set Time Scale, set the Scale to 1.0
Add a fade-in and a fade-out to a shot	Right-click the shot, click Edit Clip, click Set Fade Times, and set the fade time in seconds

Dragging the center of a shot

Reorder—Drag the center of a shot to another location in the timeline to change the order of your shots.
Clip Roll—Hold down Ctrl+⇧ Shift and drag the center of a shot to change the time window it displays without changing the shot's location or duration.
Clip Roll Stick Roll—Hold down Alt+⇧ Shift and drag the center of a shot to modify its location on the timeline. This modifies the durations of the shots before and after, without changing the selected shot's duration or time window, or the shot order.
Clip Scale—Hold down Ctrl+Alt+⇧ Shift and drag the center of a shot to create slow motion or fast motion; this stretches or compresses time by scaling the shot, without changing the shot's duration on the timeline. The playhead's position determines the center point of the stretching or compression.

Dragging a shot's head or tail

Roll, Ripple—Drag a shot's head or tail to roll it, changing the shot's duration. The rest of the shots ripple (adjust in time) to compensate.
Stick, Ripple—Hold down Alt and drag a shot's head or tail to stick it and modify the other edge.
Roll—Hold down Shift and drag a shot's head or tail away from the shot beside it to shorten its duration and create a gap between shots. This doesn't affect the other shots on the timeline.
Create Gap, Ripple—Hold down Ctrl and drag a shot's head or tail away from the shot beside it to create a gap without changing its duration. This changes the timing of other shots on the timeline.
Scale—Hold down Ctrl+Alt+⇧ Shift and drag a shot's head or tail to stretch a shot (create slow motion) or compress a shot (create fast motion). This is similar to holding down Ctrl+Alt+⇧ Shift and dragging the center of a shot, but when you drag a shot's head or tail instead, you change the shot's duration while preserving the time window.

Dragging the edit point between two shots (shot A and shot B)

Roll Roll, Ripple—Drag an edit point to roll shot A and roll shot B. This is called a rolling edit.
Stick Roll, Ripple—Hold down Ctrl and drag an edit point to stick shot A and roll shot B.
Roll Stick, Ripple—Hold down Alt and drag an edit point to roll shot A and stick shot B.
Stick Stick, Ripple—Hold down Ctrl+Alt and drag an edit point to stick shot A and stick shot B.
Scale Scale—Hold down Ctrl+Alt+⇧ Shift and drag an edit point to stretch one shot (creating slow motion) while compressing the other (creating fast motion).

Note:When you move a shot around on the timeline, any sound clip that starts inside that shot will be moved along with it. This keeps sound clips synchronized with their shots.
