What are nulls AE?
A null object is an invisible layer that you can create to be a super parent. For example, you may have created multiple layers, all of which are parented to child layers, but now you want to move everything off screen at once, or better yet, spin off screen while flying towards the camera.
What is the advantage of making a null value an object?
The advantage of this approach over a working default implementation is that a null object is very predictable and has no side effects: it does nothing. For example, a function may retrieve a list of files in a folder and perform some action on each.
How do you link a mask to a null in after effects?
Right click the mask and you should see a context menu with Tracking Mask. Select it and the mask can be tracked to the video it is applied to. The Adobe page about it is here. Another option is to apply the mask to a solid layer, then make the tracking null the parent of that layer.
Can a layer have two parents After Effects?
AfterEffects allows you to “parent” one layer to another. The child inherits transforms from the parent. This means that if you move, rotate, or scale the parent the child goes with it. The child can also have transforms of its own – on top of the inherited ones.
What is the basic understanding of using a null object?
A null object is an invisible layer that has all the properties of a visible layer, so that it can be a parent to any layer in the composition. You’ll use a null object to scale the layers of the 3D object down to a more manageable size.
How do you make an object null?
Firstly, you never set an object to null. That concept has no meaning. You can assign a value of null to a variable, but you need to distinguish between the concepts of “variable” and “object” very carefully.
What can you do with null objects in after effects?
You can parent other elements to a Null object to control the movement of the child layers by transforming the parent. This allows you to control groups of visual elements with a single Null object layer.

How to rotate object in after effects without affecting?
BUT if the rotation is set, it affects also the X/Y axis of the object, that’s why it completely screws up the created keyframes for position coordinates (if the object was moving upwards, I rotate it 90 degrees, it moves to the left). So my question is, how can I rotate the object without affecting the position, etc. Thanks.
How do you adjust layer properties in after effect?
Right-click (Windows) or Control-click (Mac OS) the underlined value and choose Edit Value. Drag the slider left or right. Click a point inside the angle control or drag the angle control line. After you click inside the angle control, you can drag outside it for more precision.
