Thank you!

Very helpful. 

I didn’t realize that I could copy and paste slices between projector actors — that will definitely simplify my workflow!

@BvG73

I always go these steps:
1. Using the internal test pattern without any picture manipulation, to have the projectors full potential fit to the screen.
2. Check if the signals picture is coming as expected. If not, check why.
3. Deciding if any adjustments are better be done in the projector or the software.

@jandraka Thank you so much! I'll give this a go today and report back. Maybe not having the return has been the culprit.

 I'm trying to import a HAP encoded wav file into my video bin

I'm confused. "HAP" is a video codec and "wav" is an audio file format. I was unware it was even possible to even create a hap.wav file, but even if you did, it wouldn't import into the video bin because .wav is an audio file format, so Isadora would try to import it as an audio file. It certainly may be possible to create a file like this, but I've never used one with Isadora and to the best of my knowledge we've never tested with this odd codec+file format combination, and therefore I'd say that hap.wav is an unsupported media format.

Follow the steps in this article about using TouchOSC with Isadora and see if you're still having issues. Sometimes it's easy to miss a step in the setup process. I just confirmed TouchOSC is working for me.

Here are some steps to try:

Make sure you're not on a network with a ton of security like university wifi. (Ideally you want a dedicated network for this so you don't have to deal with traffic from others on the same network.)On your computer, make sure you're connected to the same network as the device running TouchOSC, if you're not and you switch networks, you'll need to quit Isadora and re-launch it (not just close the Isadora file and re-open it, but actually quit the Isadora application and re-launch it). This will cause Isadora to operate using the IP it got for the new network.Open Isadora Preferences/Settings by going to Isadora > Preferences/Settings (it'll say "Settings" if you're on a newer version of macOS)In Isadora Preferences, go to the "Midi/Net" tab and make sure that under Open Sound Control (OSC) > IP Port Number it's set to 1234 (should be the default).Check what IP address Isadora is using (all the way at the bottom of Isadora Preferences, labeled "Local IP Address"). Note this IP address or keep Isadora Preferences open for the next steps so you can reference it.In TouchOSC under "Connections" make sure the first two items you can click on have the "Host" set to the same IP address that appears at the bottom of Isadora Preferences.

@Skulpture 

Nice - seeing this post I actually just added it to this semester's upcoming syllabi!

@woland Thanks

I just purchased and installed a BlackMagic Decklink Quad HDMI on my PC tower with a 4070 GPU. I can get the Quad to show HDMI input from my Panasonic AG-CX 350 via Black Magic software and the most updated OBS. Isadora shows a black screen when live capture is enabled and started. It recognizes the device, but there is a black screen/no image or audio. I double checked that my resolution out via HDMI matched what Izzy was expecting (1080p 59.97fps). I toggled between "native" and explicitly setting the exact resolution/framerate.

I remember this happening before with a completely different system/camera and I can't remember what I did to make it work, but it worked without configuration after I did that "thing".  Can anyone offer some steps to troubleshoot this issue?  So excited to have this setup and would love to make it work. :)

I made sure the OS, GPU, and software version was as updated as possible.

@demetri79 The way that a texture is mapped to a model is not decided by Isadora, it is set when the UV mapping for the model is made. This lets you specifically set which part of an image goes to which part of a models surfaces.

To do this with a cube will not be so difficult - take a look at this explanation: https://all3dp.com/2/blender-u...

There are a lot of Blender tutorials online covering this.

You can see here though that each side of the model gets its texture from a different part of the image that is being used to texture it. You can render a video that has all the smaller videos in place so they match the texture map and then play that in Isadora and feed it into the texture input of the 3d model player.

You can also dynamically create this - you can have 6 different image sources and then combine them so they have the same layout as what the model expects for its texture and UV map. You can use a virtual stage to do this. With each 6 image sources, send them to the same virtual stage and on each use the mapper to get the source content and place it on the precisely correct position and size on the virtual stage. The size of the virtual stage should be set to whatever texture aspect ratio was used in the model, ie if it was made with a 512 * 512 texture then make a square texture (you can use the texture scaling to correct things if you need).

Then when all the 6 pieces are being sent to the right locations on the virtual stage, you can get the image from the virtual stage and send that to the texture input of the model player. This will let you send any video or image to any side of the cube and be able to control the content for any side independently in real time.

@jandraka Thank you again so much for your help! We ended up trying the actor with a different projector and it worked. The projector that it worked was slightly newer and had an option to enable web control. Really grateful for your help and support! 

There are a lot of options for this. Do you want to play audio files or trigger text on the phones?

I have done some shows with audience phones and there are a few things I have found. I tried to do this from a local server (a computer on the theater) it was easier setup wise, but required the audience to be on the wifi I took with me. This has issues that can be annoying - if the wifi internet is much slower than the phones 4/5g most iPhones with switch internet to the SIM card and this can mess with access, it is also tough to to get so many phones on a portable network. 

Hosting a site remotely requires a bit more work but then you can use https (so browsers won’t complain) and it also means the audience use their own internet. If there is a large audience and you are triggering audio files then you need a fast server, if a lot of people load the site at once then all the audio needs to be downloaded from your server to all the phones. If it is text it is a lot easier.

With a very basic site design you can communicate from some control system via http post or web sockets. Either choice will let you tell the client browsers to play a specific audio file or to display a different piece of text. With an http post request you can do this directly from isadora. If this is text you can even send the text to be triggered from Isadora so it’s a system you can always alter easily. 

chagpt can write pretty much all the code for the site very easily. Make web server with nodejs that has the functionality (test locally with isadora), use GitHub for the code so you can update it easily on your server) Rent a VPS (Vultr of Hetzner are good but there is a lot of choices). Transfer your nodejs code and Client JavaScript to the server and make it run with PM2. Get a domain, setup the dns so your domain pints to the server. Setup SSL (generate a certificate and copy it to your vps) and expose the site with NGinx. Test and repair a bit! Then give out the QR code as needed and use the http post request from isadora to trigger whatever you want on time during the show. The latency should be quite low. 

There are tons of instructions online for this whole setup. If you are not keen on doing it yourself it shouldn’t be a big job. You can approach your local coder (or dm me?) and it should not cost much to do.

You can send them in a ticket using the link in my signature

@antc

Absolutely! Go for it.

Getting the crossfade between videos takes a little finessing — and sometimes there's a little ghosting/misalignment but in general I'm finding it really effective!

I've used these before. They've got quite a selection of neat sensors. If I remember correctly, the only trouble I had was with their little setup/configuration app, but once you know how to do it, you know how to do it. Once you've got it figured out, I'd suggest making a little screen recording and talking yourself through the process then uploading it to your Dropbox or Google Drive so you have it there forever, accessible from anywhere, in case it's a while between times when you use the sensor(s).

@reload2024 Isadora will take care of the edge blending very well, there is no need to do it from within a video wall processor. The only thing it needs to do is to take a 4k input and output 4x HD outputs. Isadora is ready to handle this configuration already. If the NVS810 is the only way you have output to all the projectors, then I would suggest disabling the 3060 completely, if you are just playing video and doing a blend the NVS810 should be able to handle it.

You could also take a punt on a cheap video wall controller like this (https://www.aliexpress.com/ite...) - note there are 2 models - you would likely want the more expensive 4k one and if you want 8 monitors (7 projectors and a control screen) you would need 2 (the 3060 does a max of 4 outputs - these devices count as 1). In this case remove or disable your NVS810 as well as any iGPU and use only the 3060, run these controllers at 4k60 and the outputs at 1080p60. To blend, do everything in isadora using the stage setup.

@juriaan So do you mean I would essentially be changing the color balance of the 7 horizontal "sections" of my video proper to sending them out to my actual stage with the 7 projectors?

@fred

Ok, I see now what you mean. It is very confusing as the scaling only happens sometimes. It seems to only scale in some extreme aspect deviations or the horizontal numbers exceeding the actual stage size.
When typing in the custom values, you automatically go through those extremes (19 x 1080, 192 x 1080, 1920 x 1080). But switching between the presets only sometimes changes the real scaling. When the Stage output is very wide, like your virtual stage, non of the presets seem to have an effect.
I agree with you, that this feature is, if not inconsistent, very unclear and confusing.

| I am not sure what you mean by grid settings
If you hover with the mouse over the custom size values, it say 'horizontal / vertical grid devision', which I guessed is the name of the feature and therefor called it grid settings.

@woland thanks for the detailed reply. The analogies are clear, but I do feel they are not super relevant as we are programming video not getting different height people out doors 😀

Jokes aside, again, I do understand the scaling, but I think sticking to rules for the sake of it might not be the best option. I want to suggest a few scenarios where the scaling seems to fail.

FIrst is the router and selector - the system obviously stops here with whatever mechanism is controlling it. If this scaling worked consistently I should be able to connect a counter set to a min of 0 and max of 100 and have the router or selector would switch every 25, but instead it accepts the output of the counter as an absolute value.

But this does scale with the wave generator:

But if I convert the float of the wave generator to an integer, it stops scaling as the design would suggest (the user actor just has a float in and integer out).

This is where scaling between different types seems strange.

Some actors with a variable number of inputs and outputs will update the scaling to match, the keytable actor always has its output max at 255 by default. This one would make more sense to update the scale max to the number of keys. If there are 10 keys there is no way to get to 255. This seems inconsistent with the design, the max should start off reflecting the max value that can be output from that actor. I guess if you set a different max and then change the number of keys there is a decision to make as to whether to force update the max, but if you have done made this change I guess you are ready to adjust it.

I do still feel that the use case for a boolean giving the max and min values by default is so rare that it would make more sense to have these as absolute, but again an absolute value out checkbox on each output would be cool.

@woland 

Thank you so much for all your work, I managed to create something based on what you sent, it works! Although the ideal would be to not need the keyboard - and do everything with hands control only - but it seems too complicated, since I really need to have other functions with LM in the same scene... Well, if you still have an idea, let me know. 

I did not know about this Tapwhithus software, it looks very promising! Have you made any creations with it? If so, I'd love to see it, it might be useful for my thesis :) 

Best,

Ana
