SMPTE code is encoded in an audio track, it can be easily sent and converted over distance. You can also use midi timecode for sync this works well. Many motu cards have the ability to convert to and from MTC <> LTC but their drivers for USB are awful so this only works on firewire.
It can be done in a variety of ways from Isadora but search sync in the forums, avoid jamming the position of one system into the position of another, a better way is to compare position and adjust speed of a slave accordingly, less overhead, I have worked like this a lot and been able to get pretty tight sync.
It would be much better to play the video and audio from the same system (or as much as you can)
I've read through the feed and notice @symac mentioned to make the audience wear hats. Then he could maybe solve the IR problem by mounting little IR LED with battery on the hats. You can have very fine tracking after and no more echo problem with your projection.
That seems also easier than preparing the proper IR lighting of the area
Thanks for sharing your experience with these tools. I am only just starting to work with expressions in After effects mostly through using the DUIK character animation plugin. I have seen that After Effects has realtime output (including Syphon). I know it also has the Adobe face tracking functionality. I imagine it will be far more extensible than Character Animator but the area of realtime output and expressions functionality in After Effects is still a bit opaque to me. If you come across any useful tutorials I would appreciate the link.
Also, follow this link to @DusX 's post on a handy way to reduce clutter in your patches. I've been meaning to try it out myself. Maybe not the solution you were looking for, but could help reduce the clutter and therefore make things a bit clearer.
@jandraka et al thank you for your swift responses the advise has been so valuable.
I purchased an Arduino and touch sensor to try out in our rehearsal this afternoon and I was able to trigger Isadora successfully with this little system. During the workshop we actually decided that this approach was not ideal for the performers to interact with so the Artistic Director has opted for a small i cube x system. Should be with us on Monday to test. I'm sure I'll be back on the forum with new questions very soon 😄
A great day of new learning, thanks Izzy community!
I worked it out!
I had two Common Files folders, One in the x86 folder, and one in the regular one, i had simply made the FreeFrame folder with the reciever/sender files in the wrong one.
Just a stupid little mistake, thank you for the help anyway!
Ah great news! So glad!
