Electric Hand Gday Thanks to all the help from everyone at my other post I was able to finish my first go at motion detection in Quartz Composer. The video is rather cheesy, but it was a good introduction. I used a video of me in this instead of the iSight because it was easier for me to record the result. Next time I think i'll have a go at writing a custom patch.
Thanks again for everyones help with my issues on creating this. Cheers

nicely done, Lango.
Did you end up using that thing I did where you move and it implements zoom blur? I would be happy if someone found that to be of any use, I know I dig it... It is cool to use motion blur as well.
I really like the way that you have this hand deal going on! Did you actually pull off hand detection? Kudos dude!
I want to add... I think that using motion detection to ramp up an "amount" on a CI patch, or to feed the index on a multiplexer setup with different images+fx that are hooked to render patches.... is one of the most criminally underused, easy, cool looking, ways to get some fun stuff going with motion detection. I really like this alot.
Very nice effect indeed
Hi gtoledo3, thanks for the reply. Sorry I didn't reply sooner I seemed to of missed these comments.
Sorry my mind has gone blank, cause i'm at work :) I'm not sure what work of yours you are referring to. I'm also on a PC so I can't look up the names of the patches I used.
For the shaky effect I used the CIFilter that does a zoom blur and a desaturate type patch. The center of the zoom blur is randomly around the center of the lightning ball which gives it a motion blur effect.
haha, I was hoping to make people think I did hand detection. But no, there is no hand recognition just movement detection. Notice that nothing else is moving besides my hands :)
I would have to agree. In this example it does not go amount of motion detection -> amount of CI patch effect. Instead it goes motion detection -> If above certain amount -> start timelines -> timelines are linked to the individual effects.
I can't remember the exact name of the timelines patch, but I could draw mutliple timelines (graph with value by time) and have the values of each timeline as a separate output on the patch.
This made it very easy for me to change the amounts of effects over time and see how they compare against the other effects.
Anyway, sorry if most of this post makes no sense. I'm at work so I can't look at the Quartz Composer File.
Thanks! I'll make sure to post my next project/work item.
Regards
Thanks jersmi and cybero!
For my next task i'm working on a custom patch to get a grasp on the Cocoa. I'll make sure to post it.
Regards
EDIT: hmm, looks like I replied to the wrong comment...
Yeah, I ask, because someone kept asking for a motion detection version of "psychotic.qtz" (I think that's what it was called)... and I mocked something up that was working really well for me, but it kept not working for them. In the midst of that I happened on similar idea with the zoom blur and posted it, and have really dug that... It's a cool and almost ultra obvious idea to have movement trigger blur. I liked seeing that in your clip, and was hoping it had been used since it seemed so fruitless to whoever had originally asked.
I have to say... try messing with the v002 zoom blur, and another fun thing is using motion to change the zoom blur or motion blur's (depending on what you are using) coordinates.
Oooohhhhh, I see what you are doing as far as timelines goes. Genius fakeout!!! Wow. You have given me an entirely new line of thought (trigger value historians via motion detection, anyone?)
hmm, double post...
