Could I ask a stupid question please, which is not related to your technical comment, but about the green screen needed for manycam. What is the minimal size? for teaching online?
I don’t work for Manycam, but I have just gone through the process of sizing and purchasing a green screen for myself, so I might be able to help.
The size of green screen you will need will depend on your camera lens and how you intend to frame your shot.
If you intend to capture a basic talking head shot (like a webcam shot superimposed in front of your material), then something as simple as a web around should suffice… with one exception… if your camera has a wide-angle lens, the web around does not work because you will need to bring the camera closer (or zoom in), which will distort your features in the shot.
If you want to capture most of your body standing superimposed in front of your material), then you will probably need something like a 6’ x 4’ pullup or 7’ x 5’ foldable (like a giant web around). You will need to remember not to try to move out of the virtual green screen box you are standing in and avoid any leg, arm or hand gestures that may extend beyond the green screen box because they will probably get cropped off in the transmitted shot (small hand gestures directly in front of your body - in the direction of the camera - should be safe)
If you will be moving around the shot - to get out of the way or to point out specific areas of the material you will be superimposed in front of (tv weatherman/woman style), then you will probably need a studio-like set up with an 8’ x 10’ green screen that you can stand on (unless you intend to crop out the lower third of your body - which may look odd if you are walking around and gesturing in the shot). This kind of set up is not very portable, although some people have it set up so that they can push it against a wall in the garage after use or will dismantle the green screen stand after each use.
I hope that this helps,
