String to Ignore All Files Except Video

[JamesOrlowski]

What string would I use to filter-out (ignore) all filetypes other than videos when uploading? I've tried several strings, but either my uploads ignore everything, or ignores nothing.

This was my last attempt, but it just made Cyberduck ignore everything.

^(?!.*\.(mov|mp4|mxf|avi|mkv|wmv|flv|webm|mpeg|mpg|m4v|3gp|3g2|vob|ts|mts|m2ts)$).*
