Rendering a video with transparency

I’ve created a stinger transition for my streams but I’m having trouble rendering the transparency of the video so it works on OBS. I’ve used a chroma key on the stinger (To remove the greenscreen) with a transparent colour source in a track underneath, as shown here: [image] I’ve then exported the project using the “WebM VP9 with alpha channel” preset, then loaded it into OBS, however there is still a black background rather than transparency. Is there any way to fix this?
