Hello community, while I was giving a course applying the system that Mark showed in one of his sessions for virtual performances, I found a Spout plugin for 64-bit OBS. I made a small tutorial to use it with Isadora, I share it.
Producing virtual theater with Isadora? Now there's no more need to use the Screen Capture actor, croppers, and zoomers to get your talent from Zoom into the media server. With ZoomISO, you can get each participant individually, at full HD quality, via Syphon and NDI, and the app can be fully controlled via OSC. Here's how to get started!
@paddykelly Hi, I don't think I've had any issues, certainly not how you've described. I've not done a lot with Macros in excel either, this was my first proper project. I did sometimes find it got a bit sluggish when working with a lot of values. The show we built this for had references for every edit in Night of The Living Dead, about 1100 shots. If we made changes I'd sometimes need to re-load a sheet or quite restart to get it to populate properly.
I have had problems with Sumif before though, you need to be careful when you drag/copy/paste that you're still referencing the right areas. So for example, if in cell C12 you have the formula =SUMIF(A1:A10,"video1",B1:B10) and you copy/drag this to cell C13 it will copy as =SUMIF(A2:A11,"video1",B2:B11). If you copy it to D12 it will give you =SUMIF(B1:B10,"video1",C1:C10)
This is because by default excel treats cell references as 'relative', so when you copy/paste/drag a function it will re-refrence the ranges in the formulas based on their relative position to the new cell. This is really handy when copying a 'total' for example all down one side of a table. It's more of an issue when your references are two dimensional.
Luckily there is an easy way around it. You can make references 'absolute' rather than 'relative' by adding the $ sign to your formulas. Placing a '$' before a column or row reference makes it absolute, so when you copy/paste/drag that value wont change. So, using the same example as before, if in cell C12 you had =SUMIF($A$1:$A$10,"video1",$B$1:$B$10) and copied it to C13 you would still have =SUMIF($A$1:$A$10,"video1",$B$1:$B$10).
You can use '$' selectively to only make a column absolute but keep the rows relative for example by using $A1:$A10.
Not sure if that will fix your issue but might be worth checking. I think Time2Num and Num2Time will return a #VALUE error if they reference any cells that aren't formatted how they expect them to be.
I'm going to be away for a few weeks now so won't be responding very quickly to things. Good luck.
add the alpha mask to the original mp4 movie and then export it out, right?
I would not use mp4 for this purpose. I recommend ProRes 4444. This will give you the cleanest image and alpha. You can then convert this quickly using Shutter encoder. (this is very much my personal process)
Many thanks for those two fantastic solutions and possibilities.
The more i thought of my wish to automate the process of using syphon, the less I reckoned it was the ideal solution. From previous experience, it has worked like a charm for me.
I have tried the web URL FFplugin briefly and it seems to working pretty well. I have 2 beefy machines set aside for this task and it seems to work pretty well. The Vuo software seems fantastic. I often see plugins et al but realise how little I know goes into making them. Looking at this and some of the pretty amazing things people do here, I can see how this has been elevated to a feature request.
I am more of a lurker than a contributor but I do enjoy this forum as there are some pretty smart people with some fantastic ideas out there and some post on here.
I haven't thoroughly tested it yet, but it seems to work perfectly with OSCtransmit actor.
I have used something similar in the past, linking an old iphone to a portable projector (using a lighting to HDMI adapter) and the only software that exists so far (Mulivid), but its OSC commands were very limited
It costs about 10 €, and it can be very useful for small installations since it avoids running an HDMI cable from the projector to the computer where Isadora is running.
It's not strictly Isadora-related, but I've been looking for a tool that lets you make equipment system-flow diagrams like the one in this article, and someone from Alex Lindsay's Office Hours (professional AV online community) recently pointed me to this one which looks fantastic: https://h2rgear.com/
I always try to make these for my projects because it keeps everything clear and lets you know what you are missing and need to rent/buy/source.
Just thought I'd share in case anyone else was tired of the tedium of using Vectorworks (overcomplicated for simple things), napkin drawings (not good enough), or Google Drawings (not designed for this purpose really).
So, I wanted to try the PoseOSC to see what it could do. This required manually configuring the camera because I have several camera drivers installed and it was picking the wrong one. Here's how to fix that on macOS:
Choose "About this Mac" and click "System Report"Go to the sections labeled "Cameras". Find your camera and look for the item labeled "Unique ID". On my computer, for the internal camera, it was something like 0x8033000455aca514. Right click the PoseOSC app and go into Contents > Resources > app. There you will find the file settings.jsonAt the bottom you'll find the "cameraConfig" item. You will want to change it as shown in the code snippet below. You need to replace device_id_found_in_system_report with the ID you found in step 2 above.Reboot PoseOSC and you should now get the camera you want.
<p>Seems interesting... But after they let you create an account, tells you your browser ( Firefox) is not compatible and you need to install Chrome. So Byebye Runway! ;-) <br /></p>
Sorry to hear that, I am sure there will be, or are already other implementations of this.
It is exciting to me because sampling and remixing archive material has always been part of my work. If this would have existed 20 years ago it would have saved me thousands of hours of my life spent rotoscoping by hand, because it more or less lets you pluck out what you want from a video using machine learning.

In researching the issue of displays moving themselves into different positions on Windows, I came across what seems like a really useful piece of software called UltraMon. For example, it allows you to save profiles when using multiple displays that can be recalled to set the arrangement, mirroring, scaling, etc.
Definitely worth checking out if you're a Windows user and need to frequently wrangle multiple displays.
