Troubleshoot audio or video issues

If you're having problems with the audio or video of your upload, try these troubleshooting steps to solve the issue.

Verify your video settings to fix common issues

Making changes to your video's settings can solve common audio and video issues. Follow these steps to review and change your video's settings.

Open the video in a video editing program

You can open your raw video in a desktop or online video editing program on your computer. If you recorded your video on a mobile device, you can open the video using a mobile editing app.

Verify video settings

In your video editor, double check that your video settings match our recommended upload settings.

Video settings:
  • Compression Type: H.264
  • Frame Rate: 24, 25, 30, 48, 50, 60 FPS rates are preferred. Other less-common frame rates like 23.98, 29.97, and 59.94 are also acceptable.
  • Data Rate: Automatic
  • Key Frames: Automatic
  • Frame Reordering: Unchecked
Audio/Sound settings:
  • Format: AAC
  • Click Show advanced settings and choose Constant Bit Rate as encoding strategy
Other settings:
  • Size: Choose the original size of the video
  • “Prepare for Internet Streaming”: Fast Start

Save and export

Once the video has the recommended settings, re-upload the video on YouTube.

Audio and video are out of sync

Make sure the durations of your audio and video tracks are the same. For example, if your audio plays for 50 seconds but your video only plays for 40 seconds, it could cause sync problems.

To make changes to your audio and video tracks, use a third party video editor before uploading your content to YouTube.

Audio plays on a computer but not on a mobile device

If your video's sound is playing correctly on a computer but not on a mobile device, this could be a result of the audio in your uploaded video having poor mono compatibility. When listening to stereo audio (left/right channels) on a device with a single loudspeaker, the device will convert the stereo audio to mono (single channel) before your video plays. If the stereo audio has poor mono compatibility, then the mono conversion process will degrade the video's audio quality or even silence audio altogether. This happens mostly when different audio recordings are combined into one video, for example if you're making a compilation video.
One easy way to ensure that your audio is mono compatible is to listen to the audio on a device with a single loudspeaker, such as a mobile phone. If you are hearing problems through the speaker, try listening through stereo headphones. If you hear the problem through the single loudspeaker but not through the headphones, then the problem is very likely a mono compatibility problem. Make sure your audio is "in phase."
