Any of you can feel free to hire me if you like though

Yes! I think we can start a conversation around that idea

cheers

Send me a DM anytime my friend. It would be a privilege and a honor to work with or for you.

Also that photo booth production sounds very interesting. I’ve been itching to do more installation-type work literally since I started using Isadora.

Please let me know if this works out for you or if you'd like some help refining it further. It's always nice to know whether or not what I've given to folks is a viable solution for their specific usage case.

Best wishes,

Wow thanks man!! Gonna try it today and see if it works, have been sick all week with a nasty flu. I'll send you an update later today!

Wow this is amazing! Thanks a lot for helping me!! It works great in your video, but i can't seem to make it work on my macbook. It keeps giving me a 2048 error. It also seems that the recording isn't continues but starts and stops the moment i move to a certain point, even if i'm still in frame. This is probably done through the crop node? But i don't really get how i controle this :D I've tried getting a clearer image with less discolouration, but once i do that it won't start the recording either.

Is it possible to send the file without all the non-necessary effects on it? Sorry if i'm abusing the fact that you are doing this but i can't save my files and it keeps crashing on me...

I’m off to an opera at the Met this morning, but I’ll get right on that once I get back to my house, so I’ll get you something by this afternoon.

I'm not sure what the 2048 error you mentioned means. Perhaps make a support ticket to get that sorted out.

I removed the Motion Blur, but the Threshold actor and the two Effect Mixer actors were pretty much what was making my Patch work. They're necessary in order to remove the background (and the Gaussian Blur actor just makes it look *so* much smoother).

Patch: Axanias Looping Live Capture Installation 03.izz

If you want to use the cropping to limit the tracking area to a specific bit of what the camera is actually seeing,make the Control Panel visible. That's where the controls for the cropping I build in are.
Cmd+Shift+C shows you either the Control Panel or the Workspace
Cmd+Shift+S shows you a Control Panel/Workspace split.

The reason that recording is starting and stopping on you is because the Threshold actor was calibrated to work for me, in a darkish room with my laptop as the only light source, at whatever time of day it was when I recorded that video. I used the Threshold actor to have Isadora ignore everything that wasn't brighter than "x", thereby removing the background and only seeing/tracking my hand when it got close enough to my computer, and therefore bright enough to be seen. I'd advise playing with the threshold value, or trying a different tracking method all together. That was just the easiest way to show you the proof of concept with a setup in which it was easy for me to "enter" and "exit" the tracking area while not actually having to leave my laptop camera's field of view. It also had the added bonus of solving the problem of the background becoming too bright after multiple recordings.

Ultimately, the method of tracking is up to you. You could use the Freeze actor + Effects Mixer actor set to "difference" method (thanks to @Skuplture for the tutorial), or a Kinect and infrared tracking setup, both of which should make it easy for you to remove the background. Another tracking method would be Chromakey and color tracking (again, thanks to @Skulpture for this tutorial), but then you'd have to have folks using the installation wear or hold something a specific color in order to get tracking to register, which might turn out to be rather impractical. Each presents its individual challenges, but what you have in the Patch I sent you is the skeleton of what you'll need for your installation; starting live capture and recording when tracking starts, and automatically compositing the live video with the previously recorded video once tracking is finished.

I found the 2048 error it has something to do with not being able to read the .mov file. I played around with the threshold settings and it seems i can make it work now. The program has a tendency to crash but i think the link you gave me should help with that!

Thanks a lot for helping me! I don't think i would have ever found this solution by myself!!

@Axanias

Again, my pleasure. Don't forget, as a result of doing this for you, I have a working skeleton to make an installation like this myself now too. Moreover, now anyone who searches the forum can do an installation like this as well. Thanks for letting me build an interesting idea.

Not sure why it's crashing on you though. Hasn't been doing that for me.

How goes it? Would love it if you'd keep all of us on the forum up to date on your thesis project as it develops.
