;3 Sent you a message on Discord, but since my connection is shaky I will also duplicate it here.
Since you are working on some TV adjacent stuff - I very much recommend you to try out to do stuff with ShaderGlass (you can find it either here or on Steam - it’s free). It’s fork of retrofilters used with emulators’ software, but made separate for other people who might wanna use it. It’s very easy to deal with and it can save any part of your screen with applied effect on as PNGs! !
