After uploading the video, you should get a message saying that the video will be published after processing, and then the server starts converting the video to SD or HD quality. If the conversion doesn’t start, it means your Cron job is not set up correctly.

Go to Dashboard - Server Audit and find Cron Jobs, and check if you have something like this: Last cron jobs execution - 12 Nov 2024 1:21:01 pm.
