@Kathmandale 

Thanks for the pointers, insight and knowledge. All very helpful and good information to digest.

I downloaded the videos off a list from youtube ( copyright is in place) and the exhibition is part of public facing element on vaccines. The content was existing videos given with consent for the project. I am playing about 12 videos on a loop and all was fine till I realised the designer had put a rounded rectangle in place.....

I take you points re warping. I will follow your guides ref re-using the mask directly and see how I get on. All the scene are set up with a user actor so I can trial it quickly enough.

Again, many thanks for all the advice.

By the way, you don't need the video to image actor anymore. The video  input  and vider output are mutable so you can connect a ci actor to your video player:

@mark Ah that makes sense, and gets it all in one place so easier to layout.  

Thanks, 

Mark

Thanks Mark, it works great!

@armando No of course !! 

That question came up when Dusx explained about the stage layout and that made me doubt.
Returning to the original theme therefore the masking tool is still the Edge Blend Mask, right?
Many thanks
Best,

Hi, I need to work with some bitmap images with a high grade of detail. And I want to use the black information for make a mask where I will project other information.

There I leave an image that can explain better my objectives. I want to leave the white white, and in the dark zones change the color, project a video, etc...
