Hi guys,

A client of mine wants to have a filter that resembles this:







I have the JPEG Damage filter from Genarts in AFX... but it doesnt seem to do trails like the ones you find in MPEG videos.

any suggestions ?

Thx

Ben

motion trails from footage can be achieved with time effects like echo, cc widetime and cc time blend.

if you have trapcode's particular, you can do some interesting trail-like effects using a keyed layer as an emitter that leaves behind a particle trail too.

for blocky compression artifacts, mosaic is very useful. then it's just combining mosaic'ed elements with your piece to achieve what you are after.

yeah but I feel like compression trails are very very different from normal motion trails.

Why not just compress the ever-living crap out of a copy of your footage then reimport it?

That effect is achieved by manipulating the keyframes in compressed video. Its sometimes referred to as "datamoshing" and there are plenty of how to type pages on the web - such as here:
