There are different types of iPhone out-of-sync audio problems. Reasons for iPhone sound issues may vary, and sometimes it's hard to identify the cause. Here's the good news: VideoProc offers a straight-forward solution thanks to its Force A/V Sync feature. Read on for more detailed iPhone video audio out of sync troubleshooting methodology and make the "problem-solving process" easy and quick.
1. iPhone Video Audio Out Of Sync in iMovie, FCP, Adobe Premiere Pro, etc.
The source videos shot on iPhone play well. However, when editing in iMovie, Final Cut Pro, Adobe Premiere Pro, or other easy video editing tools, the sound is not in time with the video. The frame rate can cause the issue. Videos captured by iPhone use Variable Frame Rate. Most video editors like iMovie, Final Cut Pro, Adobe Premiere Pro only support constant frame rate or have poor handling of Variable Frame Rate. This may lead to an audio sync issue and choppy video playback. To fix the issue, you can convert your iPhone footages from Variable Frame Rate to Constant Frame Rate using VideoProc.
Note: The 12.0.1 update for Premiere Pro CC 2018 adds support for Variable Frame Rate.
Step 1: Click the Video button, and select your source iPhone clip by clicking the + Video icon.
Step 2: On the Target Format section, select a format you want to keep for the video from the list.
Step 3: Click the blue RUN button to start processing your iPhone footages. Without any further ado, your iPhone videos will be changed from Variable Frame Rate to Constant Frame Rate by default.
