Chroma key for a video

[P4nd[A]]

Hi guys
First of all,I wanna thanks all Support team and OBS for making this perfect steaming software
I'm a caster
And just had an idea which came up to my mine last night with OBS and it's video plugin

Here is my idea:
I have a self-made in game HUD of Dota2 with moving and flashing object,and of course it's a video and it goes along with green screen.But I couldn't find anyway to erase the green screen or replace the green section of that video when I active it along with my steamming
It would be more fascinated and great if possible
Can anyone make a button or a plug-in to erase that green screen xD

Thanks

It would be better to use AfterEffects to do something like that, and then add the video with alpha transparency.

You can also use https://obsproject.com/forum/resources/clr-browser-source-plugin.22/
Then you have to make webgl scene with alpha support.
For exemple with three.js :

var renderer = new THREE.WebGLRenderer({ antialias : true, alpha: true });
renderer.setClearColor(0x00FF00, 0);

Thanks for your suggestion,but I'm very new at this :)
Could you make intruction with image or video instead :P
Do I have to install the JavaScript 3D library??
