      file format is MP4

       MP4 is not a good format to use this approach, since the position input of the movie player is being set, this doesn't allow the multi frame decompression used by MP4 to work as expected by the codec. 

      Try transcoding to HAP, that is the best format for dynamic playback.

      There is no link to the App. We will need to understand how this is providing the lyrics to you?

      A trick I use is:

      Create a Control Panel with a button that takes you to the next SceneMove the cursor over that button.Put tape over the optical sensor of a wireless mouse (now the cursor cannot move off of that button).Put the mouse in your pocket, on the floor, or take it apart and make a glove that completes the left-click circuit when you put your forefinger and thumb together.Now you can slap your pocket, step on the mouse, or close your fingers (with the glove idea) to trigger things.

      Further advice:

      Use a USB instead of a Bluetooth mouseUse a USB-over-cat5/6 extender to put the usb receiver for the mouse above the center of the stage (for larger stages) or just closer to the stage (if your computer is already backstage and the stage is small enough for it not to matter).TEST TEST TEST! Always bench test your setup as much as possible, then test more once you're in the actual venue.

      @milt0n i ran it via proton on steamdeck. Wouldn’t have considered it stable or that usable but it worked. Tried launching it since and it doesn’t seem to work now. I wanted to see how capable steamdeck was for projects out of curiosity

      @dusx Thanks, that really helped. It was in fact the opposite effect (to create a kind of negative fisheye process), but I tweaked the code you sent to do this.

      Dual graphics cards is unsupported (meaning we are unable to provide tech support) since we have no way to create the same/similar setup.

      With that said you can use more than one card. 
      What is important is that you don't share/mix video from one output path to another.

      So if you:

       add a movie player, and connect its output to stage 1 (using gpu1)add a movie player, and connect its output to stage 2 (using gpu2)

      Don't try to mix the two videos together in any way.. keep them separate. Mixing will require moving the texture from one gpu to the other, and will be a spped/bottleneck.

      No Isadora allows you to move video in anyway you like, so its very flexible. If you can keep the video flow simple, and maintain individual paths, you can make it work very well.

      TEST, TEST, TEST!

      Start simple, and build up.. test constantly

      Can you send the patch either here (if you're comfortable) or in a support ticket (see the link in my signature) so we can take a look at it? In medical terms, it can be hard to diagnose a patient over the phone rather than through a physical exam.

      Setup Steps: 

      Download and install IsadoraIf you don't have an Isadora license and want to be able to save your work, purchase an Isadora LicenseNote: There are short-term and long-term options for licenses. Check the store for more details.Download and install Rokoko Studio from Rokoko's website.Note: This software is what collects the live data from the suit/glovesGet a Rokoko Plus subscription so that you can stream the data to Isadora from the Rokoko Studio Software.Get your suit/gloves connected to your WiFi and ensure they show up in Rokoko StudioNote: If you are having trouble, feel free to consult:Rokoko's Onboarding Essentials YouTube playlistRokoko's help articlesDownload the Rokoko Studio Live Watcher Add-On, unzip it, and follow the setup steps inside to connect Rokoko Studio to IsadoraNote: If you are having trouble, feel free to consult Rokoko's article on connecting Rokoko Studio to Isadora.

      Once you have these devices sending you OSC, they are very easy to use. So a demo patch doesn't make much sense until you know what you want to do with the OSC data.

      I have a step back version but it's a whole day of work.

       Because I often work on things where I'm pushing Isadora to the absolute limit, I've gotten into the habit of making incremental saves every hour or two. I rarely need them, but when I do, I'm very glad to have them.
