Texture overlapping other objects

When applying a texture to material, the texture then overlaps all the other objects in the scene. Be it video texture or simple image texture.
I am defining the mesh like this:

let planeMesh = new THREE.Mesh(
        new THREE.PlaneGeometry(50, 50),
        new THREE.MeshBasicMaterial({map: videoTexture})
    );

I don’t want this to happen. What should I do?

Sorry, but it’s not clear from your description and screenshots what the problem is. Please describe in more detail the expected and actual result.
