Processing time depends on the following:
Your upload speed. Check your upload speed to make sure it’s at the recommended 5mbps or more on speedtest.net.
Video length. Longer videos will take a little longer to process.
Internet connection. When recording, make sure you are connected to a stable internet connection. If possible, disconnect from any VPNs to minimize any issues. If you do experience an interruption while recording a video, this could lead to processing issues which may not let you finalize your vidcast.
