To speed up or slow down a video in Premiere Pro:

1. Speed/Duration: Right-click the clip > “Speed/Duration” > Adjust percentage (e.g., 200% for faster, 50% for slower).

2. Rate Stretch Tool: Press R, drag the clip’s edge to adjust speed.

3. Time Remapping: Right-click FX badge > “Time Remapping > Speed” > Add keyframes and adjust the line for custom speed changes.

Use Optical Flow for smoother slow motion and keyframes for speed ramps.

• Use the Rate Stretch Tool (R) to drag the clip shorter (speed up) or longer (slow down).
• Right-click the clip, choose Speed/Duration, and adjust the percentage.
• Use Time Remapping for smooth speed changes with keyframes.
• Enable Frame Blending to avoid choppy playback.

In the timeline, right-click on the video clip you want to modify.

2. Open Speed/Duration Settings:

3. Adjust Speed:

Enter a value:

Above 100% to speed up (e.g., 200% for double speed).

Below 100% to slow down (e.g., 50% for half speed).
