   Long-shot, but: Does anyone (possibly at Apple) know if there is an internal setting to turn off shadows on system windows? (macOS Sequoia)

   Use case: I am green-screening my camera feed onto the screen (so the screen has a green background) and using that to overlay windows on my camera feed. The shadows are picking up the green and making the green screen picture quality not as good as it could be as I have to constrain the parameters more than I would otherwise have to.

     Update: problem solved without having to remove the shadows.

     Instead of a chroma key, I set the background of my screen to pure black (#000000) and I’m using Luma key. Works beautifully with everything I’ve thrown at it so far in both light and dark mode.

     Looking forward to documenting my setup after I finally record that video about Kitten’s new introspection API for the Kitten Shell (REPL).

     Yak’s shaved along the way:

     • Completely took apart my setup down to every wire and reconfigured it.
     • Spring cleaned the whole office.
     • Updated my recording/streaming process.

     :awesome:👍

     PS. Also stumbled onto JankyBorders for putting a border around the active window to make it easier to differentiate. Not sure if I’ll use it but you might find it interesting: https://github.com/FelixKratz/JankyBorders?tab=readme-ov-file#jankyborders

     So a picture is worth a thousand words and all that; this is the composition I was trying to explain :)

     @aral Very cool! What app are you using for streaming?

     @danyork I’m quite spoilt for choice these days…

     Currently, I’m doing the keying in OBS so I’m going to record/stream from there. For the latter, I have to dust off our self-hosted @owncast instance :)

     Previously, I was doing the keying in my Atem Mini Pro – that’s where the camera feed is coming from currently and where I’m feeding the screen I use for the keying (so I can go from my four-monitor regular work setup to the five-monitor recording/streaming setup just by turning on the Atem and launching OBS).

     (I also tried Meld Studio but decided to go with OBS thanks to the flexible preview window feature. It’s a deal breaking with Meld as I want to look at the exact output feed as I present. It looks like I’m looking at the overlaid screen.)

     Sorry, way more detail than you asked for :)
