1. Why Do Sound and Video Go Out of Sync?

Before exploring the solutions, it's essential to understand why sound and video sometimes become out of sync. There’s usually more than one reason this might be happening. Once you figure out what’s really going on underneath it all, it becomes a lot easier to find the approach that actually works.

• Frame rate differences

If the video was recorded at a different frame rate than it's being played back, the audio and video can slip out of sync.

• Video compression

When a video is compressed, especially if it's been downloaded from the internet, some elements may not sync properly, particularly if the audio or video files were compressed differently.

• System performance

If your computer’s running a bit slow or the gear you're working with is past its prime, it can get tricky to keep the sound and video lined up, especially when you're trying to watch something smoothly or edit without hiccups.

• Corrupt files

If a file didn’t download properly or got saved the wrong way, it might’ve gotten a little messed up. That’s when weird stuff happens; like the sound falling out of step with the video, either trailing behind or jumping ahead.

These are just a few examples of why sync issues can occur. The good news is, they can all be fixed, either automatically or manually.
