Let's get some closure on this a year later.  I went back to test adding layers and since Windows has updated, graphics drivers have updated and of course Isadora has updated I wasn't getting the same numbers.  But relatively, using the RTX was still quite a bit higher than using the Intel GPU when looking at Isadora's load stat.  Although DusX was right, adding more layers and effects added less load on the RTX above its base.  On the other hand, the mystery was about Isadora's ability to run a show and keep up FPS in a given config so I'm still concentrating on that load meter.

So still unexpected swingy numbers.  That is, until I found one setting I'd somehow missed this whole time.  In the NVIDIA Control Panel there's a setting for power management, which I set it to prefer maximum performance and rebooted.

Suddenly the test show wouldn't break the 8% barrier on RTX, within a percentage point or two of what Intel is showing now.  The setting had different options on some other computers I looked at, but its equivalent was present and did give me lower and stable load.  So problem solved, missing one setting can make things weird.

Also, the show I was given to test is sort of a mess.  Different file formats, codecs, sizes and frame rates getting mixed sure didn't help things.

@video-architect here's a quick Izzy file with the appropriate actors. You just need to change the I.P. address of the ArtNet Send actor.

Hope this helps!

Hi Izzy community! 

I make use of the Screen Capture actor quite a bit, but recently I've noticed the actor crashes Isadora as soon as it is added to a Scene, or alternatively when a Scene containing the actor is entered. Is anybody else experiencing this issue? Any ideas?

Thank you Simon

isadora 3

Isadora 3 has not been updated.
All updates since the release of Isadora 4 are in subsequent Isadora 4 releases.

I would love it for there to be a custom shapes actor that could behave a little like the Composite Mapper in Izzy Map. It would be great to have an actor that could make a custom shape by double clicking on it (like how we get to Izzy Map) to allow you to use the methods of the Composite map to create unique shapes for masks and the like. It would be amazing to have the ability to soften the edges of the shape inside this custom mapper as well.

I often do this via a virtual stage mapping a Background Colour with the Composite Mapper in a projector going to a virtual stage then Getting the Stage Image and sending this custom shape often to the Alpha Mask Actor or using it as a piece of content. It would be lovely to have an actor that does this alone, without having to use a virtual stage.

I hope that is clear. Thanks so much.

Cheers,

Cam.

@woland is this still broken in isadora 3 or just happening for me?

@gpeddino

It depends on what your text file looks like and whether you can easily reformat it. If your text looks like this:

You can use the Data array actor. By changing the Recall value, you can call up the corresponding line from your text file. 

For the same text file you can also use the "Read Text from File" actor. Set auto read to on and read mode to line. You recall the line with the start input (take care 0 is the first line)

If your text has characters before and/or after the timecode ( - 00:00:01:08,)
 you can use the Text chopper actor. 

It is IMPORTANT that the text file is in the same folder as the Izzy file.

Best regards,

@citizenjoe nope. Playback still stops after a few hundred frames backwards..

I have a text file with several markers in timecode format, and I'm trying to input these values into Isadora (with something like Read Text From File). Is there any way I could have Isadora read this file and somehow convert them into into actual timecode?

ENTTEC ODE Mk3

 I have never used this device, but it appears to support art-net.
So the example I gave will not work, as it is for usb/serial.
You can grab the Art-net tutorial file from the art-net addons page or direct at: https://troikatronix.com/files...

That should provide a starting point for getting going. If you still have issue, don't hesitate to ask.
