Earthquake Equivilant on AE???
I’ve seen a few videos that have an effect called “earthquake” that makes the screen shake; i believe its available on FCP. Is there a similar effect on After Effects?

The AE equivalent would be wiggling the position of your footage using an expression or The Wiggler (I find the latter easier for motion that doesn’t last the entire duration of the comp). Make sure you have room outside of the frame as you do this so that the edges of your footage don’t show. If you’re working in a 3D comp you can wiggle the position of the camera.

where is this “wiggler” located? I didn’t see it under the effects menu.

Use the wiggle expression.
Here’s an example applied to position: wiggle (100,15) means wiggle 100 pixels 15 times per second.
Search the COW if you need more info.

For Earthquakes or camer shakes, Quaker (an Animation Preset free from Scott Frizzle), is your one-stop shopping place (no shopping really, it’s Free!).
https://scottfrizzle.com/free.html
Note: The View Quicktime for Quaker is linked to the wrong movie, but don’t let that slight lapse fool you, the preset is a gem.
Applying Preset the first time:
Select the layer you wish to affect, and go to Animation > Apply Aniamtion Preset.
Find Quaker on your harddrive and select it (quaker.ffx).
(If you put it in your Abode After Effects>Support Files > Presets folder,
that way it will always appear in your Preset menu.)Quaker incorporates motion tile to fill in the edges of the shaking layer.
It is also very adjustable, sliders to control Quake Magnitude and Quake Frequency, keyframeable to zero and beyond.A pdf comes with the zip that explains all.

[Steve Roberts] “Use the wiggle expression.

I love the wiggle expression, but under certain circumstances The Wiggler is easier. For example, if you need your properties to start and end at the same value (which I often do for DVD Menus), or if you don’t want your ‘earthquake’ to last the entire duration of the composition. These can be accomplished with expressions, but it’s easier to use The Wiggler.
Here’s a brief rundown of the Wiggler for zygotesoup:
The Wiggler is accessible under Window > The Wiggler.
In order to use The Wiggler you will need at least 2 keyframes on your property. One will be the starting point of the wiggle and the other will be the ending.
Select these 2 keyframes when you’re working on setting up your Wiggle.
You usually won’t have to deal with most of the settings for the Wiggler, the important ones are Frequency (how often) and Magnitude (how much). One important difference with The Wiggler as opposed to the wiggle() expression is that The Wiggler only increases the value of the property. wiggle(5, 1) will wiggle between positive and negative one five times a second, The Wiggler will only wiggle between 0 and positive 1 five times a second (this is by far the biggest headache with The Wiggler).
When you’re done setting up your wiggle, hit Apply and it should create intermediary keyframes between the 2 you had selected at your desired frequency and magnitude.
If you’d like more info about it you can check the AE help.

Thanks again for all the help! I got both of these techniques to work for me. I think the quake effect works best for what im looking for. When I was reading the .pdf that came with the download i was a little confused with how to adjust the shutter angle setting. He said he reccommended a setting of 360 but I’m not sure exactly where to adjust that from. Other than that it turned out great!

Comp>Comp Setting (or Ctrl K) brings up the Comp Setting Dialog Box. Then click the “Advanced” Tab, and there you can control the Shutter Angle which affects the motion blur. You can go up to 720 for motion blur to really kick it in .I’m not talking about Quaker here, but motion blur for moving objects. I’d try 360 as suggested.
