Hi all,

I can't find a way to accomplish something that feels doable. 

During a performance I am writing/editing a piece of text that will then be projected, scrolling over a live feed video. But I need to have some of the words stand out...ideally in a different color, like Red. But those words are not newly written. In other words they can be formatted in advance. But it's a long piece of text so I need to have it scroll. The Text Draw actor would be the easiest, except you can't format specific words. 

I tried to use the screen grab actor but the white background of the Google Doc doesn't work for this because it obscures the live feed behind and the words become illegible if you mess with it too much.

I'm kind of at a loss. 

Does anybody have any ideas for me? 

Thanks in adnvace.

If none of the information in my previous comment is of any use to you in terms of diagnosing what issue you're having, it would be very helpful if you could attach a screenshot of what you see in the video preview when you hover your cursor over each of the links in these actors like this:

This way we can see what is happening at what step and actually deduce what might be going wrong. With the current screenshots we can only tell what two different final results look like but we don't know what your content looks like originally nor at any of the steps before the final output.

@eva

I can't tell from your description whether you're saying there's something wrong in both screenshots, or just one of them, but everything in the second screenshot looks correct:

• The chain of video actors from the bottom Movie Player with media number 1 has the 'intensity' set to '0' on the Projector, so we can't see any output from this chain of actors. 
  • If 'intensity' was at '100', because this Projector is set to 'layer' = '2' and 'blend' = 'transparent', this video stream would appear in front of the result of the top chain of actors (Picture Player + Movie Player with media number 27) and anywhere there was alpha in the video content coming out of the Contrast Adjust actor, we'd see the video output of the top chain of actors.
• The top chain of actors has the Projector set to 'layer' = 1', 'blend' = 'transparent', and 'intensity' = '100' so we can see this video content.
• The Video Mixer actor connected to the Zoomer and the Movie Player has 'mix amount' set to '0', so we're seeing only the video content from its 'video 1' input (so just the Picture Player, nothing from the Movie Player with media number 27).
  • Setting 'mix amount' to '100' would show us the content from the 'video 2' input, and setting 'mix amount' to anything from '1' to '99' would show us a mixture of the two video streams.
• The Add Alpha Channel actor isn't doing anything because there's nothing connected to its 'mask' input. 
  • From the Add Alpha Channel help text: "Where the 'mask' pixels are white, the resulting pixels will be opaque. Where they are black, pixels will be completely transparent. Gray values will make pixels partially transparent depending on their brightness."

With current setup I can't tell what the content of either Movie Player looks like originally. (In topmost Movie Player, the Video Mixer has its 'mix amount' input set to '0' so we're only seeing the video stream from the Picture Player, and with the bottom Movie Player we can only see the video stream from the top chain of actors inside a mask made out of the very chroma-keyed, color-inverted, and contrast-adjusted result of the bottom chain of actors.) Without knowing what the content looks like though, it seems like what's happening in the first screenshot is correct as well, since we're seeing bits of the rope picture through alpha 'holes' in the end result of the bottom chain of actors.

@eva

What video format are you using?

Do the video thumbnails look correct when you rollover the links from the Movie Players?
We first need to confirm that the video look correct before being processed by any other actors.
If you create a test scene with only a Movie Player and a Projector, can you see each movie correctly the preview if you set the movie player to play each?

Hello there, 

I am working in Isadora3, and I am having some troubles, with a video file that keeps showing something else than I have put in there. I have tried rebuilding it, same thing happens. I use a videomixer and mix two files, one shows as the real video, another shows as something else. Can you help me? And, what should I send? I have quite a few photos and videos in there.I have added 2 screenshots, one where you see the alpha chanel on, and one where its off, its two different videos?

All the best

Eva

Hi Wholand, 

Ah thanks, I will try that:)
Have a great dayEva

There is also another problem with the IP address in Isadora preferences. If you use a VPN, you get the VPN Tunnel address ( e.g. 10.2.0.2) but not the real IP address you can see in system preferences (192.168......or something like that). For Touch OSC and co you need the 192. 168..... address. It would be fine if it was possible to see both. (By the way, it is the same problem with the Apple Shortcuts app. It shows also only the VPN and the external address but not the real address in the local network. Not really a problem; then you can find the correct address in the system preferences, but it would be nicer to have it in Isadora.

Best regards, 

Jean-François

Jumping onto the sensor's onboard wifi to input details for the router

 Aha! I knew there had to be a use case I was forgetting about. This makes perfect sense.

Hi L, I ran into issues the other day when updating my Pipo sensors. Jumping onto the sensor's onboard wifi to input details for the router, then reconnecting to the router's wifi to set up the IP for the Pipo board to speak to Isadora. Also testing with various routers. I like to grab my IP from the settings menu of Isadora - it's quick and easy and if there was an 'update IP' button, then it would be more foolproof.

@dbini said:

would be perfect if it could update dynamically

 I can see it being useful to be able to choose which network it should use (and use the IP the computer has for that network) but dynamically updating seems like it could be annoying. 

Example: If I've got a LAN with no internet access set up for NDI and Isadora's using that properly, then I switch my computer in network settings to use my WiFi instead of the internet-less LAN in order to use IzzyCast or the RTMP Streamer actor or the Screen Capture actor to scrape a website, if Isadora followed my computer's network settings automatically then Isadora would be doing the opposite of what I'd actually want. 

There's some thought that needs to be put in here as to default behavior, dialogs, warnings, and what makes sense to allow automatically vs what should be required to be done manually. Overall I don't think it's ideal to have a workflow that involves switching between networks multiple times in the first place, so I'd want to just be able to manually select which network Isadora should use and I'd never want it to change anything about that automatically. This solves the major problem of the use case where I've got multiple networks running on my computer and need to disable all but one of them before launching Isadora to ensure that Isadora starts up and uses the network I want it to use, but I'm curious what workflows and use cases would involve needing to automatically switch between networks, or to switch between networks repeatedly.
