This parameter works very much like the valueAtTime() method you can use to retrieve a property's value at any given time. We are able to access these negative time values of wiggle() by using the seldom-used fifth parameter of wiggle() - time. The blue dot is tracing out the portion that occurs between zero and positive three seconds. The red dot is tracing out the portion of the path that occurs between minus three seconds and zero. The trick is that the red dot is tracing out the three-second portion of the path that occurs before time zero. It turns out that the red and blue dots are actually tracing out the same random wiggle path. That seems like quite a coincidence, right? Well, there's a little trickery going on here that is key to making this all work.

Notice that it starts near the right edge but ends up in the lower left corner - exactly where the blue dot starts. Now examine the path traced out by the red dot. It starts in the lower left corner and ends up near the middle of the right edge after three seconds. If you examine the lower movie to the right you'll see such a path traced out by the blue dot.

Visualize a graph showing the path that our layer traces out as it moves randomly from time zero through three seconds. We’ll be using this script in nearly every video we create and know you’ll find it as useful as we do.Let's say we want to create a three-second loop of wiggle motion. The Pro Content continues to grow rapidly, sign up today! Jolts are perfect for explosions, impactful footsteps, or something rushing past the camera.Ĭrate’s Camera Shake After Effects Script is exclusive for our Pro Users. These can be applied directly into the shake animation wherever you need, and give an impact to your footage. You can generate a null with the shake or apply directly to your layer. The Jolt will be applied wherever your timeline scrubber is on your timeline. We’ve also implemented a Jolt for you to choreograph your perfect set of shakes. Motion Blur – Have the script automatically set up motion blur to the shake.Īuto Scale – The script will calculate the perfect size for your footage so that the shake does not have it drift out of frame. Random Seed – Add more unique randomness to your shake.

Skip Keys – Reduce the density of keyframes (a value of 2 will place a keyframe every 3 frames instead of 1). If you’re seeking more control, we’ve also included a variety of customisable options to perfect your shake. Once you browse the built-in library of shake presets, you can then apply it directly to your footage. Earthquakes, running, handheld and more are all part of the bundle to choose from. We’ve tracked and analyzed several different pieces of footage, all recorded in different scenarios. It’s fast, fully customisable, and is packed with features. The toolkit can create a fully-realistic camera shake with only the click of a button.
