Audio Lag in iMovie while syncing with GarageBand audio
I've been trying for months now to record videos (on my iPhone X) while at the SAME TIME recording audio (with a USB condenser mic onto my brand new iMac Pro into GarageBand). And then I put it all into iMovie to edit and the same thing happens time after time after time...AUDIO LAG!
I've tried converting my videos shot in 4k and 1080 at all of the available frame rates (24, 30 and 60fps) to constant frame rates in hand break. It still lags. I've tried converting the GarageBand files into .aif and .mP4 and .wav files and still by the end of a 3 minute song I'm trying to capture...it's lagging big time.
What can I do? Please help me, oh you professional editors of the world.
Much Love,
Eric
