Hallo, I am researching the possibility of working with a motion capture system that uses Optitrack and a software called Motive, and to get the data captured in Isadora. I found a post from 2018 (https://community-test.troikatronix.com/topic/4920/body-mapping-how-to-do) that mentions Optitrack, but maybe there is some news since then on how to get the data into Isadora. Any chance I can avoid coding or expensive 3rd-party software to do so? Any experience or advice shared is much appreciated. Thanks Elena Tilli

@opmeyerThe solution here:BING copilot translated the JSON to HEX and pasted it in the TCP send actor. Worked straight away!{"jsonrpc": "2.0","method": "system.poweron"}7b 22 6a 73 6f 6e 72 70 63 22 3a 20 22 32 2e 30 22 2c 22 6d 65 74 68 6f 64 22 3a 20 22 73 79 73 74 65 6d 2e 70 6f 77 65 72 6f 6e 22 20 7d {"jsonrpc": "2.0","method": "system.poweroff" }7b 22 6a 73 6f 6e 72 70 63 22 3a 20 22 32 2e 30 22 2c 22 6d 65 74 68 6f 64 22 3a 20 22 73 79 73 74 65 6d 2e 70 6f 77 65 72 6f 66 66 22 20 7d

@koolsteelerThe simplest way would be to use the Capture Stage to Picture actor to get a still image "thumbnail" of what each Scene looks like, then put a Picture Player actor in each Scene showing the picture taken of the next scene, and link the output of the Picture Player actor to a Monitor Control.

@video-architect Non of the listed software tools are capable of doing a perfect mapping of this curvy front easily. Only very expensive media server, like disguise or Pixera can do the 3D calculations on the fly and add accurate edge blend. considering your very short time frame, I would go the simplest route. Just do separate layers. There are several ways to generate several layers in Isadora. For the most flexible way, use multiple projectors per scene. Every projector offers his own layer value and izzi map function. With the right blend mode set, you can send these projectors to the same stage.Projector/ Layer 1: The background with pre cut video or a masking in izzi map.Projector/ Layer 2: The pillars and general front.You could even go with a projector actor for each object you'd like to map separately. For the masking use an extra layer which goes to a virtual stage. With this you can do a very flexible (alpha-) masking within izzy map. Do this for every layer you feel to need a separate mapping. If you need to warp each layer separately, pipe them through a virtual stage as well, before finally adding them to the masking layer with the keying (a separate one, then) An edge blend is very complex here (as is the whole thing because of the curves and levels).But you can do a simple manual edge blend with a similar technique, using a virtual stage and do the edge blend actor on it. Regarding the calculations for the hardware projectors, you should use the foremost front as the projection screen. everything behind it, will be overlapping anyway. PS: I used a chroma key for the masks, as in my experience the luma doesn't work as well.

@bonemap wow !!! Looks amazingThanks for shearing. BestMaxi RIL

@eva said: if I have multiple video actors in a stage running in the background, that I have activated through the "activate scene"-actor, is there then a way to controll that scene, concretely when the videos start if I am running a show in another scene?  Yes.FILE DOWNLOAD: https://www.dropbox.com/scl/fo/hx3x0pq568up5muyekw8o/h?rlkey=rxqp3wxznkcprjveetmx07hvj&dl=0"Control" SceneBackground Scene

@fred Sure, for the encoders, but not for the faders. Motors compensate what you describe for infinite rotary faders I love that. The only problem with the Xtouch is that you have to reconfigure it completely before using it with Isadora. Faders spit out data on 2 different controller numbers as they are both on/off buttons on one channel and sliders on another channel. And this confuses the control watcher and even the different MIDI LEARN that exist out there as Isadora user actors. And there is more : the software that Behringer created to reconfigure all the controllers buttons faders and encoders on the Xtouch is pc only. I had to buy Parallel desktop too. The good news is that the Berringer software works well even if you don't buy windows inside Parallel Desktop. Anyone can use it with the non-customizable windows version that comes with Parallel.

@fred said: @skulpture Here are some shadertoy examples of optical flow:https://www.shadertoy.com/view...https://www.shadertoy.com/view... />https://www.shadertoy.com/view...The" class="redactor-linkify-object">https://www.shadertoy.com/view... issue with this is that the computation of what is moving where and when is in a shader, this means if you want to do anything with that data, you need to do it in a shader. Getting data out of shaders is not always easy, and is best done with compute shaders, and this means windows only. The Nvidia SDK will do the computation on the GPU and pass data back to the CPU so it can be used for other calculations.  That makes a lot of sense. Thanks.

@vidasonik no problem. my knowledge has tight limits, however..:-) you should be able to use the Ableton Connection kit for OSC devices to talk to the onboard ones in Izzy.  But even better for what you are trying (if i understand it...) is the free 'LiveGrabber' OSC Ableton tools from Showsync. The 'Analysis Grabber' can 'grab' audio frequency data which you can send via OSC to Izzy. I haven't tried it, but it should work. https://www.showsync.com/tools...

@woland Hello, thanks again Lucas. And thanks to everybody contributing to this interesting thread. As @ril says limitaition is wifi saturation. Do we wknow how much bandwidth NDI is using to have 3 1080p cameras on a dedicated wifi network ? As far as I know we can have at least 3 because, according to obsbot tail tech pagesQuoting :Does NDI work over WiFi? High Bandwidth NDI will work over a wireless network but at a reduced frame rate depending on the bandwidth available. As a general rule of thumb 100Mbit is recommended per 1080p video feed. The actual bandwidth used may be much less than 100Mbit (even below 20Mbit) depending on the complexity and size of the video being sent. Otherwise if only a WiFi network is available, using NDI|HX sources is recommended. Such as most NDI Cameras and NDI|HX encoders/decoders.

@dbini Oh! You are absolutely right...I don't know why I didn't see it.I'm going to explore it and maybe come back with new questions. Thank you very much for opening my eyes!Best,Maxi

@riodio You also normally have to use Z translate to move the object backwards, so its comes into view. I normally start at -50

@jandraka thank u so much for this hint. now it works like charm.  just in time! Although i had to redo the whole patch.  

@fred and @DusX Thanks for the heads up. I did get the integrated GPU working alongside the dedicated GPU just as a test. Next step will be to get all four projectors hooked up and build some test cues to see what happens...I also want to check the Star-Tech extender to see if it works as an option... 

@jfg said: other (negative) consequences  The Ungrouped layer method allows you to 'interlace' image layers during scene transitions. This can create some very interesting effects, since Projector layer settings are used.However, this method is not default since by default it mixes scenes in an additive manner, where the newer Grouped by Scene option flattens each scene individually and mixes them with a more 'cinematic' crossfade not possible with the Ungrouped option.
