hi everyone,

I'm working on a show in south of france. 
We have live video, we control differents sources tanks to an Atem. 
I have a computer with Millumin, sending recorded video, link on the atem as a source. 

What i would like to do, is to send recorded video on the live video, so we can see both source, one on the other. 
I have an export project from After effect set for transparence. But when import it in millumin, the background is black. I can control thanks to the atem, to have 50/50 of recorded and live video. 
But i can't remove the black background
Do you if there any effect in Millumin for that ? 


  • Hello @clement,

    What is your codec used for your video ? ProRes-4444 ?
    What is your version of Millumin ? 2.18.w ?

  • Hello @clement,

    Sorry, I'm not sure to understand : does it work now ?
    If not, please provide a short MOV file with the problem. Thank you.
