Been seeing a video playback problem
in both the last release and in the current beta

The material that I am playing is mostly cars going side to side and as such it is very easy to see drop frames

The video will run fine for about 3 to 4 minutes and then will drop a few frames and then usually recover…  and then start dropping again a few minutes later

It seems to be similar to this report

Re: [playback movie stutters on slo-mo from fcp](/topic/8511/playback-movie-stutters-on-slo-mo-from-fcp)

I am running three screens that are being chopped out of a single threewide HD file

For running the three screens and sync — super simple and very basic set up. —  Everything is set up properly. The output projectors are all set at 60 FPS and the video is 29.97 —   The playback load is usually about 4% and isadora says that the playback FPS is rock solid

I have gotten the same results using both H264 files and ProRes files

At the moment, the only way to avoid the dropped-frames is to switch out of isadora and into another program every few minutes
(or going into the settings, while the show program is playing and changing the general service setting)

I started the project on a M1 max silicon, mini Mac using the latest release of isadora

Then tried using the current beta
Then I tried moving to an M2 Max PowerBook pro
I tried changing a couple of projectors, different audio interfaces, etc. 

(i did not have an intel machine to test on)

On these machines with all versions of isadora, the end result was always the same

This does not seem to be actually a problem in isadora, but rather in the silicon Mac’s?

the dropout frames, don’t all happen on all three screens at the same time, but rather screen number one will sometimes get dropped out frames, sometimes screen two, or screen three — The dropped frames never occur synchronously on the output.. it always randomly on one or two of the screens.

My general feeling is that the system itself is trying to move, perhaps from performance cores to efficiency cores? Or perhaps the ProRes engines in the silicon Macs are causing the CPU to do so little that the system tries to move into a low-power mode?

As I said, before, switching from isadora to another active program, in my case, I was running resolve in the background
 I did this hoping to force more cpu cycles to get used— helped but I have to actively switch from back and forth from one program to the other 
Just having Resolve running and keeping Isadora in the front was not enough

Any thoughts?

Anyway to make sure the movie player is getting full use/priority of the system?

Ok, i have not  found a solution. I  have an Izzifile created in  3.2.7b28. The latest download version is 3.2.6. I of course get constant errors about the "created in  a newer version" i can't cross paste  the scene to an older version. what  am i to  do?!

Hi helpers:)

I have for two days now had trouble tracking skeletons with my Kinect. I can see the depth map, but it is really hard to get some proper tracking. I am working with 2 dancers and have tried to go through the trouble shooting. I have the Kinect model 1414, but yesterday I added the file from the readme - and I am wondering if this can cause the trouble. Yesterday though I also had troubles. 
I can see there is bodies in the space but they have no color. I am working with a setup I used before, so I dont really know what this is. Maybe someone can help? I am on a Mac Studio running Rosetta mode. What would btw be useful to share in this situation? test-med-vertical-dance.izz 
All the best

hi All

Have been running v2 projectors with ( 4 chan audio)video/audio file for some years when I bring same file into v3 it will show projector and audio files but wont play them 

Brought video/audio  file in to v3 have no control over audio. 
do I have to bring in files separately to an audio player to play so I have to split audio/ video 

It’s a project musical theatre show I’ve been running for some years now. 

I take my audio from USB of mac to midas m32 audio desk 

Help

New to all this....

I want to project a 360 image on a sculpture using 4 portable projectors. What portable projectors are best? I think the deciding factor is if wifi is enabled. Can anyone direct me to some specs and information on this? (hardware-wise)

These are some of the products I am looking at 

XGIMI Elfin Mini Projector, NEBULA by Anker Capsule 3 Laser, Epson, EpiqVision, mini 

I am needing to create an array of objects within my Javascript Actor and am having difficulties in creating the necessary class definition

When I do the following:

class Test{}

function main()
{return 0;}

I get a compiler error saying that "Test has already been declared". However, if I do the following:

function main() {

class Test{}

return 0;}

(putting the class definition within the body of the main function) then it works just fine.

I have not found any documentation that specifies that class definitions have to be within a function.  Eventually I will need to develop different class structures and would want to put these definitions in an external .JS file

Any thoughts/suggestions?

Hello, and happy new year. I watched the guru session 9 OSC - I installed GyrOSC onto my iPhone and set the target IP and port as Mark suggested. However, I am unable to detect the stream in Isadora. When it did not work with the Ventura operating system I tried a machine with Mojave. Does it have to be an Ipad? Are there other ports or something I need to set - that I am missing from the turorial?

I am a bit dejected as I spent a while trying to connect an Arduino with a serial watcher (I could see the data in the monitor) but not in the watcher and then I tried with the firmata....I will try FaceOSC next...

Thanks

Hello everyone,

I'm moving an Isadora patch, made on my mac, to a PC for a public installation, however, I've just come across a problem. My patch has a number of core audio actors (AUmixer, AUAudioDeviceOutput etc.), of course, I now realise these aren't available on the PC (Windows 10). Are there any alternative actors with similar functionality that I can install to allow me to recreate the mac version on my PC?

thanks,

Nic

I'd love to be able to reverse the direction of a wave generator as described in this thread I made earlier (https://community.troikatronix...). I've been pointed in the direction of some workarounds by this awesome community but this function would be useful to have built right into the Wave generator actor, and would certainly make this task more efficient. I was thinking that it could be handled with a trigger input, or maybe even by allowing the freq input to take negative values, like the speed input of the movie player.

Cheers

JP

Is there any way to reverse the direction of a wave generator? I have a patch where I'm reversing the playback of some videos on demand, and it would be helpful to also be able to reverse some of the modulation I'm doing at the same time. This might be more of a feature request, but I wanted to pick the community's brain and see if it was possible through some combination of actors first. Thanks in advance!
