Audio and video not in sync MacBook Pro

Many users reported that audio and video are not in sync on their MacBook Pro. This can be a problem if you tend to enjoy multimedia content, so today we’re going to show you how to fix this problem once and for all.

What to do if audio and video aren’t in sync on Mac?

1. Convert the media file and use 48kHz frequency

If you’re having this issue while playing a local media file, you might want to try converting it. Few users are suggesting converting your file to MP4 using a video converter. Even if your file is already in MP4 format, converting it with a tool such as a Handbrake might help.

While converting the media file, pay close attention to the audio frequency rate. Some devices might use a 44.1kHz rate while your MacBook might be using a 48kHz frequency. To fix the problem, make sure you resample the audio using a 48kHz frequency.

2. Try a different media player

In case your audio and video aren’t in sync on your MacBook while playing a local file, you might be able to fix the problem simply by switching to a different multimedia player. Few users reported that this issue appears only in iTunes but not in other players such as VLC.

If you can, try using a different media player until you manage to find the root cause of the problem.

3. Try using a different web browser

Users reported that these problems are specific to Safari and that the audio and video sync just fine in other browsers, such as Opera One.

Be sure to pick a browser alternative that has well-integrated security that protects against malicious websites and web attacks. You should also look for an option that does not use too many resources because that can also impact the quality of streaming content.

We recommend Opera One because it integrates a VPN and an adblocker and is reported to use very few PC resources. On top of that, it includes social-media integrations, keyboard shortcuts, customizable themes, AI and plenty of free add-ons.
