Parametric filter won't apply to video

I saw this tutorial on Reddit and wanted to try and replicate it. I designed a patch and animated it in After Effects, then exported as .mov (Quicktime, animation codec). In Photoshop, I convert the export to a smart object, but I can't get the embroidery parametric filter to apply. It just duplicates the layer (in the layers and in the timeline) but doesn't apply any effect at all. Not sure if this is a bug or whether I'm doing something wrong. Any ideas?
