You can add a film shake effect in Premiere Pro by using the Transform effect and manipulating the position property with keyframes.
Here's a step-by-step guide:
-
Locate the Transform Effect: In the Effects panel, search for "Transform" and drag it onto the clip you want to shake.
-
Access Effects Controls: Go to the "Effects Controls" panel. This is where you'll adjust the Transform properties.
-
Set Keyframes:
- Navigate to the point in your clip where you want the shake to begin.
- In the Effects Controls panel, find the "Position" property under "Transform."
- Click the stopwatch icon next to "Position" to create a keyframe. This marks the starting point.
- Move the playhead to the point where you want the shake to end.
- Click the stopwatch icon again to create another keyframe. This marks the ending point.
-
Introduce the Shake:
- Move the playhead between the two keyframes you just created, specifically to a point where you want the shake to be at its most intense.
- Adjust the "Position" values (the X and Y coordinates) slightly. For example, you might increase the X-value by a few pixels, then decrease the Y-value by a few pixels. This creates a subtle shift in the scene. The amount of the change determines the intensity of the shake. Larger changes create a more violent shake.
- Add additional keyframes between your start and end points to create varying levels of shake throughout the effect. Randomly adjust the position slightly at each keyframe.
-
Fine-Tune (Optional):
- Motion Blur: Under the Transform effect settings, uncheck the "Use Composition's Shutter Angle" box and then increase the "Shutter Angle" setting to add motion blur to the shake effect, making it look more realistic. Be careful not to overdo it.
- Scale: For a more dynamic shake, you could also add subtle adjustments to the "Scale" property using the same keyframing technique.
Example:
Let's say you want to add a shake to a clip between 1 second and 3 seconds.
- Place the playhead at 1 second. Create a keyframe for "Position."
- Place the playhead at 3 seconds. Create another keyframe for "Position."
- Place the playhead at 2 seconds. Change the "Position" values slightly (e.g., X +5 pixels, Y -3 pixels). This creates the shake at its peak.
- Add additional keyframes between 1 and 3 seconds, adjusting the position randomly.
- In the Transform settings, increase the shutter angle.
By adjusting the frequency and magnitude of the position changes, you can customize the film shake to achieve the desired effect. Experiment with different values and keyframe placements to find the best look for your project.
