Hi folks,
I’m having a hardware issue that — try as I might — I can’t seem to fix.
Basically, it’s a two projector set up where one projector keeps on dropping signal. This is just my studio set up — this show can actually run with one projector, but I don’t have enough throw distance in my studio. But I need to solve this for rehearsals to happen.
it’s not an Isadora issue, but I just wonder if anybody has had a similar experience and knows something I could try.
here are the details…
Rig: Mac Studio M3 Ultra, Isadora 4.1.3. External monitor on back HDMI (main display, never drops). Two projectors, each: Mac → USB-C-to-HDMI dongle → OREI UHD-EXB400R-K HDBaseT transmitter → ~100ft Cat6 → receiver → HDMI → projector.
• ViewSonic PS600W (1280×800, lamp DLP) — this one drops
• Springtree ST-C801P (1920×1200, laser DLP) — glitches whenever the ViewSonic drops
Problem: The ViewSonic randomly loses source and recovers. The Springtree glitches at the same moment — I assume macOS re-enumerating displays. Totally irregular timing, sometimes minutes after startup, sometimes two hours in.
Tried: new Cat6, swapped chains between projectors, split the two across the Mac’s separate display port groups, ran each solo through its full chain (both clean alone — only fails with both connected), checked projector standby/signal settings.
Next: considering a HDMI EDID emulator maybe???
Has anyone had anything similar happen. I’m very used to running multiple projector set ups with mixed resolutions, but I’ve never seen this. That said the large projector and the Mac Studio are both new…
TIA!

I would transcode it again using shutter encoder or something. It sounds to me like a corrupted video codec so recreating it is probably your best choice.
Hello,
last week i wanted to play an mp4 file in a theater - it was playing smooth during a test but on the beginning of the show the load goes up to 500% and the movie on the projection was just stuttering in 11 fps. I used a very powerfull Win 11 (Version 25H2) the specs in the picture below - anyone any idea what could be the reason for that strange behavior?

Ok,makes sense. We should get together for a beer sometime but not so many as last time! Got a new studio and its the best I've ever had.

I used to be able to have a Videos and Pictures Tab at the top of the bin picker.
I don't think this was ever possible. I tried with 3.2.6 and 4.0.0 and it wasn't do-able in either of those.
It also wouldn't make sense functionality-wise because then the same Control ID would be used by Picture Players and Movie Players, but they use different kinds of media and those media have different index numbers that don't matter to the other kind of Player actor.
I'm using a work around. Adding another bin picker just takes up more screen monitor space. No Biggy.
Hi, I used to be able to have a Videos and Pictures Tab at the top of the bin picker.
Now it's all the Tabs or only one. If I try to add another Tab, the first one goes away.

is there a reason to run it in Rosetta ?
The only real reason to run Isadora in Rosetta mode is to use the 'OpenNI Tracker' actor which is EOL.
The core libraries used for the OpenNI tracker, haven't been and will not be updated for use with Apple Arm processors, so the OpenNI Tracker can't be updated either unfortunately.

is there a way to make numpy and openNI work in ARM mode?
Maybe, this configuration isn't tested. You may be able to install a python virtual environment via terminal forcing the process to run under x86_64.
That will give you an 'intel' version of Python, and if the version is exact (it is 3.12.10 currently) Isadora (running under Rosetta) may be able to use it, and when you install the required modules via PIP, you could use something like:
arch -x86_64 /path/to/python3 -m pip install --only-binary=:all: numpy==2.5.2
to force the intel version of numpy to be installed.
...As I said, this is untested, and definitely a more advanced install/config. I would avoid it to be honest.

every other tutorial that i could find.
Did you find and read through this article about Pythoner and NumPy yet? https://support.troikatronix.com/support/solutions/articles/13000118388
Here is the touch OSC file and a striped down Izzy file, it was made in 2017 hopefully it's useful to you. I took out the 3 smartphones, next to the iPad they all had individual movies, pictures and audio files pushed to their device.
