Fake TAA shaking

Hello everybody. Someone can take the time and write a simple shader that will shake the screen a little, like a real TAA does (I'm zero in programming)
The idea is that the picture will be shaken and smoothed with a shader from BlueSkyDefender.
Of course, it will be impossible to play like this, but maybe you can make beautiful screenshots without flickering..

This is called jittering and cannot be done in post. It shifts the projection matrix slightly (in sub-pixel space!! the offsets are smaller than a pixel), so that the rasterized samples are slightly offset (similar to MSAA the idea is to generate more samples per pixel, except that it is done over multiple frames instead of within a single frame).
Just shifting the pixel data around in acreenspace would be useless for this and not produce the desired effect.

Hey!

Follow up question: Is it possible to write a shader that applies BlueSkyDefenders TAA to a shader instead of the entire screen? Like with a before and after effect shader with the third in the middle?

Reason i am asking is that i am using TAA to get rid of most jittering that MXAA and similar depth shaders produce, but TAA blurs the entire screen. However, if TAA would only affect the shadows drawn by MXAA the jittering on foliage etc. could finaly be fixed.
