welcome
   here's a bunch of others who have free plugins or resources available for final cut pro. Some of them are commercial sites that offer one or two freebies, others are all free. I trawl the net every now and then looking for them, but if you know of any I've missed, let me know.

 
   
your name here If you've developed a plug-in you'd like to share for free, or if you know of one that I've missed, let me know. I'm quite happy to host them on this site, too.
AE freemart A lot of Adobe After Effects and Photoshop (and Premier AFAIK) compatible plugins will work with Final Cut Pro. This is an ok site for free After Effects plugin links. Results may vary.
AMAFX How's your Japanese? Well don't fret, look for the link that says amafx.sit near the bottom of the page. Or you can try this machine translation of the page. You'll find some spiffy generators including a cute one for making raindrops, and a random line generator. N.T. who wrote the scripts sent me gridrand and gridfollow, two scripts that aren't on the macdtv site, you can download them here. They add multiple copies of the frame in either a random grid (a bit like a DV tape fast-forwarding) or steady grid with time delay (a bit like a security camera). Cracking stuff! These are open source and N.T. says you may freely use and modify these scripts.
Artmetic Artmetic make lots of FCP plugins, most of which would be good for low end, corporate work, and there's a free posterize plugin available on their site
Boris Boris make a whole range of commercial plug-ins for FCP After Effects and more. They're particularly good for text effects (Although my better text plug in is faster ;). There's a free cartooner plug in available, and some demos of other stuff.
Buena Software Buena make commercial plug ins, including a very interesting Curves editor. On their site is a free camera flash plug in, for that tiiiired camera flash effect, (Matt Sandström does one too) as well as some demos.
Bunnyworld A particle generator for FCP. Just like you'd pay lots of money to get with After Effects or Combustion. Well nearly. Don't be alarmed if it looks weird in the canvas, renders come out ok. Don't grok the name though. Bunnyworld..?
CHV They make commercial FCP plug ins, but have a silk and fog plug-in for free download
Digiconform Digiconform make systems for conforming 24fps negative from NLE timelines. On the website, although unrelated, is a Wiggle plug in that Rainer Standke wrote. It simulates aged film jumping around in the gate. Similar to the Eureka jiggler plugin
Digital Film Tools Download demos and this free fast blur filter. It's supposed to be faster than the blur in FCP, which wouldna' surprise me at all. The link on their downloads page is goatse though.The correct link is here.
Tom Henderson An impressive garbage matte filter with up to 50 bezier points. The Bezier handles let you create curves between points, as you would with a mask in After Effects or whatnot. I've always been meaning to write a plug in that does this, but Tom has saved me the trouble. Tom also has written this plugin that draws screen guides which don't appear in the final render (text file, you have to save to disk or copy paste). He says that he'll be doing more, so check back.
Kafwang.com Home to the venerable Eureka plug ins, now up to version 5.0, and fully compatible with Final cut 4+. They continue in their admirable tradition of giving stuff away for free, with a plugin bundle that includes abstract, an infra red simulator, and a trackable garbage matte. See Ken Stone's page for a review of these filters
Lyric studios A free Shadow / Highlight plugin for correcting over / under exposure. Also some interesting commercial plugins including a motion tracker.
Simon Kirby My separated at birth twin web page. A Final Cut Pro and related software resources page, has links to free plugins, as well as all sorts of other useful stuff. Lots of info for any Final Cut Professional. And he comes from Austraya too, mooooit!
Joe Maller Start here. A great source of Final Cut Pro plugins. Most filters are not free, but they're worth the money. Demos are available too. Also on Joe's site is the brilliant FXScript reference. If you want to have a go, go here first.
Graeme Nattress lotsa useful commercial filters, including film effects and tweakage, a bar graph generator, and a line generator. Some free plugins are available for download including a gradient dissolve, a cadence detect for checking 3:2 pulldown, and more. A very useful person, Graeme helped Patrick Sheffield with his Technicolor Plugin.
Perfectly Polite Pictures Nice looking site with a free film look plugin available, and a mystery one soon to come.. Wish I had her web design smarts..
River Rock Studios some commercial plugins of the make-your-video-look-like-film variety, and a coupla freebies: Jitterbug, for jittering stuff around, and Chromatic Glow, which looks like a very useful glow plugin.
Dustin Sallings A generous collection of free, open-source plugins including strobe effects and transitions, random blocks and progressive blur. Also on his projects page are some handy AppleScripts including a letterboxing and a de-anamorphising (is that a word?) droplet.
Matt Sandström The Too Much Too Soon plug ins include blackrestore for putting the black back into footage, noise reduction, RGB gamma and more. My favourite transition effect is Matt's Wind Blur Cross. Some good, useful, free and open source plug-ins from a no-nonsense website.

Patrick Sheffield

 Patrick from Pistolera Post has built a very useful looking two-strip technicolor emulation plugin and explains the algorithm behind it here.
new
spherico Some useful FCP tools including a free field swapper that works by shifting pixels (as opposed to my time shifting field swapper) and a utility for doing scheduled recordings with FCP
Adam Wilt A Horizontal Chroma Blur for cleaning up steppy edges in DV's nasty 4:1:1 colour space, and Chroma Offset for fixing chroma timing problems. You don't know what 4:1:1 and Chroma timing means? Hey newb, you need to check out the site for comprehensive technical information about video, and DV.
