What does the preview windows shows? (Output -> Force Stage Preview)
If is shows the picture correct, there might be two reasons.
1. Most projectors offer the possibility of scaling and cropping the input. Maybe try a full reset of the projector settings.
What projector is used?
2. Some GPUs offer a scaling and manipulation of the output. Check the GPUs settings software (Nvidia or AMD)
Hi there, I hope someone can help here.
Yesterday, I made a simpel setup for a friend, to execute a number of videos from Isadora, so she could make the fades between videos live in ther performance.
Unfortunately, when we moved the file to her computer (from my Mac Studio to her Lenovo T470) something happened in the projection. The projection of the video from her computer is moved towards the right, that means, you can only see about half of the projection and also it is zoomed in, when it comes out of the projector. This doesnt show in IsadoraI don't know her computer, so I am not sure what to do, but maybe someone here knows the problem or has an idea?
Any suggestions?
Any help is very much apreciated:)
All the best
Eva
That's what I was trying to offer you with a sample patch, but it took a while as I probably ran into a bug. Some of the izzy map layer (I did one for each shutter) started to have some crazy output scaling. After a lot of trial and error, a rearrangement of the according mapping layers reset and fixed it. This moment I realized, that a rearrangement of the mapping layers, reorders the published inputs.
Both might be addressed in a bug and/or feature request.
Anyway, I am a big fan of doing masks in izzy map. Beside going the virtual stage way, Woland mentioned, you can always simply work with several projector actors, functioning as a layer each. Just set the layer value of the projector with the masks to the highest.
This way you can always update it for the whole project by putting it into a user actor (while editing) or in a separate background scene (interactive).
Also, I refuse to admit defeat. (It's still not perfect because you can't adjust the points for each side individually, but you can do the angle and crop amount for each "shutter" on its own.)

(I'm not sure whether IzzyMap + Virtual Stage is more efficient processing-power-wise, but I'd be interested to see a comparison of the Load between the two patches.)
Oh yup, IzzyMap's a valid way to do it. You could even use a Virtual Stage with IzzyMap to do your custom crop, then use Get Stage Image to pull that custom-cropped image back in, mix it with other stuff, and send it out to a physical display on a normal Stage.
Thanx so much.
Not really what I was looking for. I want to have individual control of several points.
This is how I solved it. Maybe there is a smarter way. );

In this case, the actor allows me to select up 120 fps. But it isn't clear to me if this fps is actually changing.
The help text may help clarify this:

Is there a way to evaluate if that particular actor is now working at 120 fps vs 30? [...] Is there a way to evaluate what the fps speed of a particular video stream is working at locally
A quick and dirty way is to use the 'hertz out' output of the Tap Tempo actor (since it'll get a trigger every frame), but you will see this fluctuate:
@aolis said:
Does the fact that fps goal is set to 30 just mean that regardless of what I put in that setting it will only ever work at 30fps?
A quick test says yes.
Importantly, it seems that:
- You need to press "OK" to close Isadora Preferences after changing the Target Frame Rate for it to take effect.
- On Mac, you'll probably want to set "Display Refresh" to "Off" in Isadora Preferences > General > Frame Rate / Tasks > Display Refresh.
- Even if the Target Frame Rate is '120' in Isadora Preferences and the 'fps' input property of the OpenNI Tracker BETA actor is set to '120', the frame rate for the depth video from a Kinect model 1414 doesn't seem to really want to go higher than about 30, regardless of target frame rate. (See picture below.)
- If the Target Frame Rate is '120' in Isadora Preferences and the 'fps' input property of the OpenNI Tracker BETA actor is set to '120', the frame rate for the color video from a Kinect model 1414 will hit 120 fps. (See picture below.)
Best wishes,
Woland
