Transparent media file not working

[PerryGamingYT]

i exported a media file from resolve with a transparent background, i tested it out after render and it is transparent but whern i upload the media file to obs there is a black box in the location of the transparent area, anyone know a fix ? here is a log if needed https://obsproject.com/logs/foAK1Nnt3Oo60qOd thanks you

OBS doesn't output transparency. It has a black background that can't be removed except to cover it with something else, so that might be what you're seeing.
