Improper Encoding

One of the top culprits is improper encoding. Encoding involves compressing a video and audio file into a playable format, like MP4. If audio and video are encoded separately or with mismatched parameters, the timing can easily go off. Think of encoding like assembling a puzzle; if pieces don’t fit exactly, the final picture won’t be seamless.

Frame Rate Mismatch

MP4 playback relies on consistent frame rates to sync correctly. Sometimes, audio and video are recorded at different rates, causing them to drift apart over time. Imagine walking in step with a friend, then suddenly changing your pace; you’ll quickly end up out of sync. The same happens in video files.

Device Compatibility Issues

Even if an MP4 file is perfectly encoded, playback issues can arise from device incompatibility. Different players and hardware handle synchronization differently, so a file that plays fine on one device might go out of sync on another. This is common when switching between older devices and newer media players.
