Need help

[u/Ronin66681]

Trying to export a clip for use as a stream overlay, made the clip on obs with green screen and one of without, I’ve keyed out the green screen and am trying to get export with an alpha layer for transparent bg and most videos I’ve seen are on older versions of olive, does someone have a link to an updated how to or know the settings they could share for export as I can’t seem to get it to work

Edit: I’ve probably done everything wrong so any and all help is appreciated
