Lesson 2: Pacing and Time Manipulation

Who can describe what a slow motion video looks like?

Slow Motion
Speed
Freeze Frames
Optical Flow
Frame Sampling

DVP.04 Production: Identify and describe the elements of production to effectively deliver a message.

Slow Motion & Fast Motion (Speed/Duration)
The most direct way to change a clip’s speed is the Speed/Duration command.
The Workflow: Right-click a clip on the timeline and select Speed/Duration (Shortcut: Cmd+R / Ctrl+R).
Slow Motion: Setting the speed to 50% doubles the clip's duration.
Math Check: If you filmed at 60fps and put it on a 24fps timeline, you can slow it down to 40% for perfectly smooth "cinematic" motion.
Fast Motion: Setting the speed to 200% creates a "time-lapse" effect, useful for showing long processes (like a student drawing or a crowd moving) quickly.
Ripple Edit: Check the Ripple Edit, Shifting Trailing Clips box to ensure that when your clip gets longer or shorter, the rest of your timeline moves to accommodate it, preventing gaps.
2. Fixing "Choppy" Video: Optical Flow
If you slow down a standard clip (filmed at 24fps or 30fps) to 50%, it often looks "stuttery" because there aren't enough frames. Premiere Pro can "hallucinate" new frames to fix this.
Frame Sampling (Default): Simply repeats existing frames.
Frame Blending: Overlaps frames to create a "motion blur" look.
Optical Flow: The pro choice. Premiere analyzes pixel movement and creates brand-new frames to bridge the gap.
Note: You must Render the clip (Press the Enter key) to see the smooth Optical Flow result.
3. Freeze Frames (Frame Hold)
Use these to "stop time," often used for character introductions or to give the audience time to read text.
Add Frame Hold: Right-click a clip and select Add Frame Hold. This turns the entire clip into a still image.
Insert Frame Hold Segment: The more versatile option. This slices your clip and inserts a 2-second "freeze" in the middle, then continues playing the video.
Frame Hold Options: Right-click > Frame Hold Options to choose which specific frame (In point, Out point, or Playhead) the freeze should use.

Students choose their own clips to edit.

1. The Setup: Import a clip of someone performing an action (a skateboard trick, a dance move, or even someone dropping a pencil).
2. The Slow-Mo: Identify the "climax" of the action and slow that specific section to 50%.
3. The Fix: Apply Optical Flow to the slow-mo section and render the timeline.
4. The Freeze: At the very peak of the action, use Insert Frame Hold Segment to pause the video for exactly 1 second.
5. The Fast-Forward: Speed up the "recovery" (the part after the action) to 250% to finish the clip with high energy.
