Resyncing audio with iMovie in iOS.

There’s a horrible bug in the iOS that causes audio from Lightning or USB-connected microphones, such as the Blue Raspberry, Apogee MiC, Line 6 Sonic Port VX and Apogee One that makes it lag almost a second behind the video. Makes all your movies look like bad foreign language dubs. Fortunately it’s fixable on your iPhone or iPad in iMovie:

  1. Tap iMovie’s Video tab
  2. Tap the video to be resynced.
  3. Tap the Share icon below the video preview.
  4. From the bottom row choose Create Movie.
  5. Tap Create New Movie.
  6. Tap the Back icon to the left of the Play button.
  7. Pinch out until you get to maximum zoom.
  8. Tap the movie track twice.
  9. Tap Detach Audio. The audio track appears in green below the video.
  10. Drag the yellow box at the end of the audio track to first frame of video. Now for some noodling:
  11. Drag the audio track left and play. Repeat until they sync up.
  12. Tap Done.
  13. Tap the Share icon.
  14. Choose Save Video from bottom row.

Aligning the tracks will seem difficult the first time you do it, but it gets easier with experience.

iMovie zoom tip.

  • Put an index finger on either side of the Play head and drag out.
