I don't know those fandoms, and I'm pretty new to this myself, so I'm sure there are many people who can give you much better recs. But I had a quick look round -

Lots of Enterprise vids:

I know I saw a mention of a Sleepy Hollow vid somewhere - ah, Mudd's Video Space:

Haven't seen these, so I hope they're what you're looking for.

There are a whole lot of recent vids for movies (not counting the obvious fandoms like LOTR and Star Wars) - it seems to be an emerging trend. Permetaform has done several, including vids of Fifth Element, the Ring, and Pirates of the Caribbean.
