Hey There... And is it possible to capture stage to picture in differents bins ? Can different bins be differents media folder ?Idea is to make > Video In watcher  > a green treatment in > virtual stage 1> capture stage picture in picture bin "green"> Same Video In watcher > a red treatment in > virtual stage 2 stage > capture stage picture in bin "red"

 This is not currently possible but I already put in a feature request for this when I was looking at your original post. As far as Isadora being able to "group" red and green pictures for you, I was able to make an example for you. It involves:

Naming the pictures as you take them with the Capture Stage to Picture actorParsing the name of every new picture file to determine if it's 'red' or 'green'Saving the name and media index of the new picture file into one of two Data Array actors (one for red and one for green)Using a Counter actor to recall the entries in the Data Array actor (so you can sequentially recall the pictures that are part of each group and their media index numbers.)

The third Scene ("Sorting Red/Green Pictures") in this updated example file has the programming for this.

i cant' figure out how to crossfade 2 picture when recalling via Get Media Count > Get media index > picture player ? Any idea ?

Check out the second Scene in the new example file above.

Unless I'm misremembering (I don't use my Blackmagic device very often), that's not what the iPad is outputting, it's what the Blackmagic device is currently set to in Blackmagic's hardware configuration software, Desktop Video Setup. Isadora has no control over what the Blackmagic hardware is configured to do, you have to check Blackmagic's Desktop Video Setup software to see how you've configured your device, then make the Input Format in Isadora's Live Capture Settings match that.

This file of mine has some comments that explain how I used the limit-scale value actors inside it: https://troikatronix.com/add-ons/live-drawing-example/

This video tutorial on the TroikaTronix Youtube channel on value scaling might also be helpful: https://youtu.be/MG3pbjPHOGc

matching the movie tint colors with the side lights in a dynamic way

 that sounds like a great idea.

@woland

Perfet Woland I need to try matte++ I gonna see the link below and the manual page 394...

Thx a lot. 

Hi Gertjan,

I don't know if you have the chance to choose whatever projector you want. I own a Fuji FP-Z5000 (discontinued now), and I've used the Z8000 as well, and there is a Z6000 (I think it is the newest).

The fixed lens is a 0.35-0.37:1, it has a very good lens shift, and a surprisingly even light for being that short-throw. I typically use it to fill a 8 x 5.5 m, screen. There are no focus issues. On the Z5000 it is important to be orthogonal to the screen in order to keep uniform focus. The newer ones have an iterative 2 step focus that accounts for that.

This would allow you to go for rear projection, and the flexibility provided by the strong lens shift can ease your placement.

The projector is not easy to find. So in case of interest I would contact directly with Fuji-Europe in Germany (that's what I did) and they referred me to their Spanish headquarters.

Good luck

I do not speak Javascript, but I suspect these links probably contain examples of some of the code you'll need:

Defining variables (storing team scores as variables): https://www.w3schools.com/js/js_variables.asp

Javascript arrays (storing team names and scores together): https://www.w3schools.com/js/js_arrays.asp

Sorting Arrays (to sort the teams by score): https://www.w3schools.com/js/js_array_sort.asp 

This Youtube video might also help

There is some weirdness. When I add user input actors for intensity and active, they sometimes default to "0" or "1" no matter what I do. Also, the order that the user input boxes appear in the scene editor seems to be pretty arbitrary.

 You may want to watch our tutorial video on User Actors

@dbini

It could be that you connected them to something which has a range that can't include a negative number (like the intensity input of a Projector actor which goes from 0-100) which caused the actor to mutate and adopt the range of the input to which it was connected.

@notdoc Thanks, It's easy to do. As there as many seasoned users available, and the forum is very active, that a Tip's & Trick's area is established as tutorials usually miss this 'way to work' option. Just a thought.

@mr_j Thank you!

@steinster

These are the 2 parameter types supported for input at this time. Isadora does not have a matching list type available. If you need multiple values you will need to create multiple inputs.
That article is the most complete documentation for the actor currently.

you can use the OSC projection mapping from the add-on page:

What exactly do you mean by "moving background"? Are there elements in the background that are moving around, or are there multiple backgrounds that you're trying to switch between? If you're trying to scroll through the same or different backgrounds, you may want to google how to construct one or more crankies (which are often used in puppetry performances). Here's a simple example and more complex example.

I'm also not sure what you mean by:

Is there a way to track hands moving objects objects and cut them out from a surface to add them to an image? I dont know if this can be done in eyes ++, but if it is possible, then I can spare a videoscreen in the background and a camera pointing on to that - because it seems like a bit of a clumsy setup - but this is so far my imagination.

I understand that you are trying to remove the person's hands from the image, but are you trying to move a puppet around in front of a physical background, or a projected background? One possible solution could be to put the puppet on a stick shadow-puppet style, or attach fishing line in two places to the puppet and then hold both tightly outside the camera's view so that you can move the puppet around that way. If you did either of those you wouldn't have a hand in the shot at all. Another possible solution is to have two cameras, one that is aimed at your scenic background, and another that's aimed at a small, well-lit greenscreen with your performer wearing a glove of the same color (you could also try another color like blue, red, or yellow though since there's green in your character). Then you pull both video feeds together and use two different Projector actors with 'blend' set to 'transparent' and the 'layer' input for the character's Projector actor set to a higher number than the 'layer' input on the background's Projector actor.

Here's an example file for that: >>>Greenscreen Example File<<<

There's also a second Scene in that file that should show you how to do the same two-video feed combination workflow, but with a black background behind the character and your performer wearing a black glove.

Obviously, you'll need to tweak values and things to get either Scene to work with live video feeds but I included some Shapes and Text Draw actors to act as stand-ins that demonstrate how the background and character video feeds are combined in both Scenes.

If I misunderstood what you're trying to do, feel free to explain in greater detail.

Best wishes,

Woland

Hey guys, i'm triying to do a "Muybridge-Marey inspiration" material with some black and white pictures ( jpg 1mb ) that i put in a picture player and send to a 3D  projector to  move them in a 3d stage space.

I have 2 questions 

a)  my computer is very slow I guess the patch is not well done ( Mac RetinaPro, 2018, i9,  6hearts, 32g ram, 2400 mmhz,radeaon pro vega 4  gigas). He is using 35%  when Im runing it. I move picture with a Pulse generator, cause I want to be able to change the speed.I didnt make a preview in mp4  so you gonna say "but you can move the speed of the film also", maybe this is an issue?

b) do anyone know how to change a color picture to a black & white in an easy way in Isadora ?

Thanks a lot 

@laobra ( Ad Kaplan )

@dusx Thank you! Not a bad idea! I'll give that a shot, but it's going to be a bit before I can get back to it... will update when I know.

@woland

thanks you guys! - will let you know if we go for the Betaversion and Python....

 I hope I am reading between the lines and that there might be a way to do that in future, as I requested in my feature request seven years ago

I wasn't trying to imply that we're currently working on it, just that it's on our radar as a feature that is often requested and would be very useful to add. I'd really like this feature to already exist or be in active development as well, but at the moment we've got our hands full with IzzyCast. (Though as a result of requiring a few new features for IzzyCast, we've added a number of handy updates to the Control Panel.)

the animator was putting files for me in a shared Dropbox folder, and as he revised these he was simply overwriting the old version in Dropbox. Meanwhile the composer is sending me files via GoogleDrive, also overwriting old versions with new, and the script from which we were generating the captions was shared via iCloud. I can't copy and paste these from their various locations into the same folder as the Isadora file, else I won't get the updated assets. 

You can ask your collaborators to not use three different platforms to provide you with files, e.g. create a shared Dropbox or Google Drive folder before the production and tell your collaborators that that's where the content needs to go. Additionally, putting everything in the same shared Dropbox or Google Drive folder means it's easier to port the show to a different computer since you could just download it. I've done just this for a number of productions and when I finish I desync the folder from my computer and the online folder becomes my archive for the show.

@jjhp3 there is this https://genkiinstruments.com/p... and https://www.bonnersmusic.co.uk...

If you can do the Freeze method with the IR feed from a depth camera like a Kinect then you don't need to worry about what the lighting state is.
