I have a fake brick wall for that “I’m in a loft” look). Were I to start again, I might go for a more practical option such as the Elgato collapsible green screen. As much space as possible between the presenter and the green screen to avoid shadows from the presenter lights (see below).Two metres width is minimum, go for much wider if you have the space. In general, brighter lights translate directly into better video quality.But the bigger the distance, the larger the green screen has to be. I use older bright bulbs, because that’s what I have left over from my photography hobby, but modern LED lighting is much more practical and controllable (and not as hot!). I don’t point the main lights directly at myself, but at the wall so it bounces back like a big softlight). I also added a ring light around the camera-not strictly necessary, but great for closeups, and it results in less annoying shadows on the green screen. Second set of lighting: as evenly as possible across the green screen.This is harder than it seems, and can require extra lights: e.g. One just behind the presenter, facing up and back towards the green screen, to compensate the shadows of the higher front lights. Points for style: a spotlight above and slightly behind the presenter, pointing down, helps create a crisp separation.A camera that outputs a clean HDMI signal (720p is fine for live, up to 4K if you’re doing recordings).I use a Sony RX100 VII, which is expensive and overkill for this (but it’s a great travel camera for conferences, etc.) You can do it with just a webcam, but the quality is typically worse, it’s going to be harder to physically align things, and you’ll have less control over the exposure. A mini- or micro-HDMI to HDMI cable (depending on your camera).The Elgato Camlink 4k (note this is required because it’s about HDMI in, not out) External power for the camera (you don’t want to have to worry about the batteries going dead).You’re dealing with multiple video feeds. I have a 2018 15” MacBook Pro with 32Gb of memory, and the fan goes crazy. The easiest way to get the presentation slides as a video feed is to use a separate monitor.Internet: wired ethernet is typically much faster and more reliable than wifi.But a friend with a Asus Chromebook said that that actually worked a lot better for streaming than his MBP, so □□♂️. Obviously requires an HDMI cable to the computer, and potentially a converter (e.g.It is theoretically possible to do it without, but harder (you'd have to reserve part of your laptop screen for the presentation, then stream just that part).
