    You are most welcome. It's what we are here for.

  • Hi again, sorry to write again about the same thing but I feel something could be done better.

    This is how I did it (image attached) but it looks a bit complicated and I'm zooming in the image at the end and I'm affraid I'm losing resolution. What do you think ?

    Would this work?

    Unless your webcam has a very high resolution I think you will always lose quality/resolution as you are upscaling the video to fit a 1920*2060 size.


  • in fact, it could be done very simpler (in a macro) but I'l still oversizing the image… is there a better way ? Am I losing definition ? f69766-multiple-projector-simple.png

    Sure you are loosing resolution, you are scaling an image to the double size of its source.

    You might also take a look at the 'chopper' actor.

    Also, assuming your using 1920*1080 your vertical size of 2060 seems wrong.
    If you want to not loose image quality, your source video should be  1920*2160, then cut into the 2 halves and run to the projectors.. 
    That would allow zero scaling, and would give you the best image quality (I suggest the chopper actor for the cutting of the image)

    As @michel says this is the main issue in terms of quality "you are scaling an image to the double size of its source"

    If you can get a higher resolution camera this would help a lot. 

  • thanks to you for the help! the 'chopper' actor that @DusX advised looks like the best way to do it without complication. I was hoping to have a edge blending possibility in case the projectors I'm going to have don't have the option, is there a way to di it in izzy ? thanks again to you 3 for the help.

    all the best from Marseille

    Yes that would be the "edge blend mask" actor.
