hi friends and helpful people:) :)

I have been asked to make a mapping for a tower with 3 projectors making 1 long projection on a church tower on a light festival. Someone else than me is taking care of the positioning of the projectors, and I am now seeking advice for how to run the project? Any good experiences? E.g. 1. Run it with Isadora from a computer?

2. Export it for 3 media players? Or can you do it with one? I only tried to run more projectors directly from isadora but sine this is an instalation, what is more safe and easy and a good solution?

Thank you for helping.

All the best

Eva

@michel

you can collect all media first, and when the project is finished you can maybe delete all unused media items.

@kirschkematthias

The main reason is that you cannot cover all circumstances. If your goal is to collect only the media that is actually used — and not everything stored in the media bin — Isadora can be used differently compared to other software. See this post:

Hi there,

I would prefere a solution like Reaper: when you save the first time Isadora should create a folder, and inside a media folder (Or two for folms and picture), the Isadora show, an undo file or folder and a backup folder. In the prefs you could allow to move, or copy the files.

All this should be easy to put into Isadora, and I wonder why it is not yet implemented?!?

many greetings Matth

I did note that the pathnames to the assets did not change in the newly saved version

 No, The project file and Isadora need to be re-opened, facilitating the Media Search. After this search (it should find the local files) it will save the new paths when saved. I was just suggesting, making a backup of the file before re-opening the project with Isadora, since it would be easy to save and lose the remote filepaths.  I'm working on another process right now for filepaths embedded in the project file. It won't be possible to get everything, especially for advanced Pythoner projects (shouldn't need to, if they follow best practices). Right now I can find, DataArray files, Top Level Python linked files, Files linked in Javascript via read() and include(), and I am able to expand this still. I will add .oni next and try to get a complete scan.  I think I will have this script output a report, that is human readable, and can be edited by hand. Specifically, per found file, an 'Include' setting, so that specific files can be excluded from the next step of collecting, which will be handled by another script.

I would set the 'size px' to 6, 'repetitions' to 6, and 'spacing px' to 1?

 Sure, that will work. You may want to crop/chop your video to narrow down on the region/s you want to select color from. I generally select the section of video I want to analyze, then scale it down (as low as 6px by 6px for your case) and then feed that into the Matrix Color Send actor. By scaling down you are basically averaging all the colors in a zone down to the one pixel. 
So for example, if you selected a 60 px by 120px area as the control area from your video feed, you could scale that down to 6x6 and get a fair representation of the colors on those 36 zones/blocks. Depending on your goal, you may need to experiment a bit to find the right balance of color blending vs accuracy.

One question about the Matrix color send actor in regards to the video to light in a matrix of non LED Pars....I want to reformat my video to a 6x6 Matrix. I currently have it set to rows. Does this mean I would set the 'size px' to 6, 'repetitions' to 6, and 'spacing px' to 1? I'm not yet familiar with how the scaling works here. Here's some example screenshots of the PD side of things.

 @DusX @bonemap I feel like one of you is better equipped to answer this question.

@woland

Its working! thanks.

sadora also allows several files to be associated with a scene through various actors, like Data Array etc. and even .oni skeleton files so these get left out of the 'collect all process' or do yiu think there is another way to scrape a project for associated files?

 I might have a solution to this.. I am working on something.

Thanks I’ll take a look.
