in general, resizing on the gpu isn't nearly the resource hog that cpu resizing was. This provides a lot more freedom when working gpu video actors.

Still some processes are heavier than others so it's good to keep an eye on your Load. Specifically things like Eyes, or Measure Color will still use a lot of cpu and can benifit from scaled down video as an input. Using scaler before these types of actors is my approach.

I also tend to use 'get video size' rather often so that I can easily see the size of video in different areas as I build a patch. Once it's working as I want, I generally remove them.

I will often use 'Get stage size' combined 'scaler' to force a video to the size of my output before running any processing. But in the end you really have many options and a lot of flexibility.

I have made quick and dirty visualizers using the shapes and slit scan actors. 

Just set the width and height in the shapes actor (to the window size) and change the height or ver post based on the value..  use the Slit Scan to create the effect.

@dusx great idea! Thanks for the tip. I’ll put that in!

its a fairly new realtime web data socket (any sort of data).
see: https://www.tutorialspoint.com...
Many frameworks have support for Websockets now (not just JS as the article totes). Its been a web standard for a number of years.

@mark

Wow, thanks a lot, you all!  I am going to look at the code as soon as I get time....

@mr_j

The default zoom range of the projector is already from 0 to 1000. You can change the scale max of it to 100 000 or more.

But yes, I can initiate also the close-down Isadora procedure by sending a timed key (for instance “X”) from the AppleScript app (registered by Key Table Watcher actor, which triggers the close-down procedure), and then make the AppleScript app wait for at least the length of the capture cycle, before closing the project/Isadora – not deleting files, not saving patch. (So, all the timing would actually come from the AppleScript app.)

 Excellent Idea. Let us know if it works!

thanks for the help.

I'm on mac and I usually capture alpha channel with the HAP Alpha codec, works great.

Be aware that compressing HAP is pretty heavy. If it works on your machine, great... but users with older/slower machines should be aware that they may run into bandwidth issues recording to HAP, and might be better off using AppleProRes 4444. (I mean, encoding video is always costly.. APR is going to eat up bandwidth too.)

Hi there @valerieoliveiro, 

Most Izzy users use an Enttec DMX USB Pro giving you 512 channels of data to work with, and if you have the drivers correctly installed it works quite well ;)

1) How to setup the hardware 

You will need the following hardware :

  Dimmerpacks DMX cable (Check the input of the Dimmerpacks and the output pins of your Enttec. If they are the same you are golden, if not you need an plug to convert 5 to 3 or the other way around) Enttec DMX USB Pro Izzy on a Windows / Mac computer

Set the hardware address of the dimmerpack (DMX start), some dimmers have an little menu for that, others have dipswitches. Look up the manual and sometimes a power reset is required for the settings to take effect (learned this the hard way)

Connect the computer to the Enttec using the USB cable provided. Connect the DMX cable to the OUTPUT of the Enttec and connect the other end of the cable to the INPUT of the Dimmerpack (not the output or thru)

2) Are there particular configurations in Isadora? Is there a patch or an actor that I should be aware of?

Look in the plugin library here https://troikatronix.com/plugi...

3) Will this help me control fading and looping of all these lighting channels? How? If not, what will I be able to control?

Yeah, with above actor you can output the desired data, what is required from you is that you create the patch to make the values loop. You can do this quite easily with Enveloppe Generators++ and sequential triggers.

@dritter

I found a solution to this problem, which solved my problems in Windows 10 with Isadora and CS6 After Effects. This article describes setting the Compatibility Mode for apps in Windows 10. Everything is working much better now and Adobe Media Encoder has stopped crashing when transcoding DNX files to HAP.

Thanks Fred, but I think they want to make something based on the Live Drawing actor that can be controlled realtime. Maybe we need to keep it really simple...

Hello @bill-cottman,

you are welcome to vote for the regarding feature request. ;-)

Thank you Dill

@dusx

Hi DusX,

Thanks for your reply!

I have been switching on and off some of the options in Mission Control and after relogging into my user it worked. Now I need to have a closer look and see what exactly was causing the problem.

Thanks a lot, you guys rock!  

@dusx

Excellent solution. Thank you.

@kdobbe sorry stupid question, found it "control watcher" thanks 

@administrators fred Thank you !! already install and working. 

again check that opening the safari I immediately get latency. But in reharsel situation with wifi off latency appeared. Then will be the low light condition what is bothering?

You could mimic the effect with a pulse generator and an envelope generator attached to the the intensity parameter of a projector.... You could add a HLS Actor if you need those functions...

Just a thought.

Cheers,

Hugh
