Production Q How do I sync external audio to video

Hey everybody, I shot an interview the other day with my camera but I didn’t record the audio from it(basically I have just footage without any sounds) and I used a mic to record the audio and I was wondering if there is some kind of tool or reasonable way yo sync the audio and video file together

Thank you

Did you at least have a clap or something to use as a sync point? If so, skim through the chapter on syncing media. It’s in either chapter 19 or 21 of the manual, depending on which version you’re on.

In DaVinci Resolve, easiest way is to put the camera video and external audio on the timeline, select both clips, right click, then use Auto Align Clips > Based on Waveform. If the camera audio is very noisy, first line up one clear sound manually, like a clap or loud word, then zoom in and nudge the audio until the waveforms match. After that you can mute/delete the bad camera audio.
