I think this thread may have answers for you: https://community.troikatronix.com/topic/8946/answered-light-flicker-between-scenes-artnet-dmx

@mark_m

I'm curious, as I did not know about these XML/XMP Headers in videofiles. As well I couldn't find to much of information about this topic. Could you elaborate, which file types does this support? And does this need specific export/render settings (e.g. in Adobe Premiere).

Maybe you can offer a link to more explanations.

Thank you

@Eva I understand but you talked about "transition from one stage to the next". Stage in Isadora is JUST video. That is why, to try to help, I asked if by saying "transition from one stage to the other" you meant "transition from one scene to the other.

@eva

It’s not that it is easy but the tools to do this kind of work are mature and advanced. You will likely, with any approach need to evaluate the workflow in two stages. The first, how well the initial background removal works and second how difficult it is to refine the separation- you will likely have to do some manual removal of the wires and general cleaning of the matte. 

Personally I would suggest using Davinci resolve as its newest magic mask iteration is very advanced and uses Resolves own AI engine to do the extraction. This is only available in the paid studio version not the free version of the software. 

Here is a tutorial that can get you started:

here is another video that shows a few more advanced features including using fusion (which is inside Resolve), as well as removing things from being tracked (which you may have to do with the wires). Overall though this works very well and is simple to use with lots of options to refine the mask.

Definitely make things as easy as possible for the system so use steady camera shots, great lighting (and try to get good contrast between the foreground and background. Use a good quality camera, something that has a global shutter and at least 422 colour encoding. 

Getting good quality video with high contrast foreground and background will make any of the workflows you use much easier. 

With good quality video this should not be too difficult. There is also a lot you can do to edit and refine your video once you have a basic mask prepared even if it is not perfect, using other tracking tools inside resolve. You can also export the separated footage with an alpha channel that can be used inside isadora or any other editing software if you want to work with the content further in another application. 

Note that this requires some good compute resources, so a high end GPU on windows or a late model mac with Apple Silicon (m1, m2, m3) and good amount of memory.

@Armando It is the color of the lamps that is flickering not the video:)

@Eva Do you mean from one scene to the other ? Stages, being video normally have nothing to do with the DMX 

Hi,

I have a setup with dmx + 8 Astera lamps. I have used the patch with the dmx universe enntec compatible and the lights are working fine. But when I transition from 1 stage to the next, there is a little flicker or blink in the light before it changes color. Is there a way to make it smooth? I imagine something with a virtual stage - I remember seeing it somewhere, but Im not sure what to put in there  and how to make it smooth:) 
I would appreciate any help:)

All the best 
Eva

@jtsteph

with all respect, exporting an EDL should be an unnecessary extra step, as all the marker info is contained in the XML header file of the video file itself.

@dusx

that’s great you have my Premiere file working! Fantastic!!

I will send you a Resolve version in the next couple days, unless @jsteph can send you one sooner?

cheers

rotoscoping

 Hi fred, it sounds actually very easy. So, it can also work if you have wires that are hanging in front of the dancers? They are connected on each side of the hip so that they can spin.Thanks for helping:)

Now, when I try to open Syphon (to then re-install the OBS Virtual Cam), the icon appears on the dock, but the actual window doesn't appear. If I go to help>install OBS Virtual Camera Plugin it waits and then closes the Syphon app. I can't get any further. Any ideas? 

 FWIW I have the same problem and I'm on Ventura 13.6.7.

I installed Syphon Virtual Webcam after already having the latest OBS installed and when I launch it the icon shows up in the doc, but no main window. Interacting with the Virtual Webcam in any way (like the help -> install OBS Virtual Camera Plugin) causes the program to close..

Just a bit more info for debugging in case it's helpful
