Troubleshooting Fast Video Playback on macOS

Quick Answer

If a video created with the GemHub plays too fast on YouTube after uploading from your Mac, there are two likely causes. First, check that YouTube's playback speed is set to "Normal." If that setting is correct, the issue is likely a known macOS bug that can be fixed by restarting your computer.

Before You Start

  • You will need access to the video you uploaded to YouTube.

  • You will need access to the Mac computer used to upload the video.

Steps

  1. Check YouTube Playback Speed: Open your video on YouTube. Click the settings gear icon in the video player. In the menu that appears, select "Playback speed" and ensure it is set to "Normal."

  2. Test Playback: Play the video again. If it now plays at the correct speed, your issue is resolved.

  3. Restart Your Mac: If the YouTube playback speed was already set to "Normal" and the video still plays too fast, the problem is likely a temporary bug in macOS related to its audio and video services. Save your work and restart your Mac.

  4. Test Playback After Restart: After your Mac has fully restarted, open the video on YouTube again. The issue should now be resolved.

Expected Result

After checking your YouTube settings and restarting your Mac, your video will play at its normal, recorded speed on YouTube and other platforms.
