I was wondering if it's possible to make a certain part of footage (including the audio) "stutter" or appear jerky by using After Effects?
Below I have an example from a music video that uses the effect I am trying to achieve. It's at the very start so you won't have to sit through too much.
You can easily keyframe stuttering motion in AE using The Wiggler ... I'm sure there's an expressions method too, but I'm not the right guy to advise you on expressions.
Figuring out how to do it via a couple keyframes and The Wiggler will be pretty simple so, if you're trying to literally reproduce the effect in the example, it may be more important to note that the entire frame isn't stuttering, which means the singer is a separate plate from the background ... either via chromakeying or rotoscoping ... neither of which are basics territory so you may want to look for tutorials on the subjects.
To duplicate the look, you wouldn't need to go into AE at all. You could just do this in your NLE by taking little snippets of footage and copying and pasting it over and over.
You could do it in AE with Time remapping, split your layer so each wiggling part is separate and set your Time Remapping keyframes on your little piece and do a loopOut expression to repeat it over and over.
