iPhone Video files have audio clipped

Has anyone noticed an issue with the audio track on video files produced by the iPhone (in my case with iPhone 13 Pro Max or 14 Pro Max) ?


Probably not noticeable until you get into detailed edit, but I've noticed that the first couple of frames of video files have no audio.

The audio only starts after the second frame. Tried High Efficiency and Most Compatible formats and also tried HD 30fps, 4K 30fps and 4K 60fps.

If you edit 2 video clips together and their sound tracks have a reasonable high volume of sound (eg background traffic noise, etc etc), then when playback passes between the clips, there is a noticeable 'blip' as you pass over the gap in the audio.

The only workaround seems to be to truncate at least the first couple of frames from each clip.


I've discovered this problem using iPhone video files imported to Corel VideoStudiio on my PC, but also using Apple's own iMovie software on the phone.


I intend to raise with Apple Support but just wondered if anyone else had come across this.

Hi Stevewelham,


It sounds like you've done well isolating the issue and testing with recording on different frame rates. You can also test with any protective case removed and any Bluetooth audio devices disconnected. If the microphones on your iPhone aren't working


Additionally, you can check the stereo recording options with the steps below found in the article here: Change the camera’s video recording settings on iPhone


"Turn stereo recording on and off


On iPhone XS, iPhone XR, and later, iPhone uses multiple microphones to achieve stereo sound. To turn off stereo recording, go to Settings > Camera, then turn off Record Stereo Sound."


Should the issue remain, reaching out to Apple Support directly would be the next step to report and have them further assist. If needed, connect with them using the link here: Get Support


Cheers.
