you posted to the ideas and suggestions (for OBS Studio development)
This appears to be a support request, in which case you should post to the Operating System forum matching your OS, and follow the pinned post regarding posting an OBS Studio session log
Also, you want to provide more detail, as your post above doesn't tell me what you were doing, or what problem you are asking about? are you using facebook's live/producer page, and seeing a preview of the video you are sending? if not, fix that first
