How to Sync Audio and Video in DaVinci Resolve

By May 09,2017 19:15 pm

Gone are the times when one had to manually sync the audio or resort to different plugin and software. This can be done in the Media Pool with a few easy steps. In this article, we will introduce how to sync audio and video in different situations, such as the video footage and audio file has the same timecode metadata, and video footage shot with a DSLR having onboard sound. No matter if you are using the timecode or the waveform method, you can easily auto sync your footage with the help of the DaVinci Resolve.

Syncing Audio and Video in DaVinci Resolve

Typically, there are 3 ways of synchronizing the video and audio in DaVinci Resolve.

Method 1: Using Timecodes to Sync Audio and Video

  1. To start a new project in DaVinci Resolve, you need to go to Project Settings and turn off the ‘Use local version for new clips in timeline’ from the Color page.
  2.  sync video audio 1

  3. Now add the video and audio files to the Media Pool and get them organized. The video and audio file needs to be present in the same bin.
  4. Now you need to right click the bin and select ‘Auto Sync Audio based on Timecode’ (in which case the in-cam audio tracks will be replaced with the external audio) or ‘Auto Sync Audio Based on Timecode and append tracks’(in this case the in-cam audio is preserved while the external audio tracks are added).

In case the audio is not synced properly, then you need to follow the steps mentioned below:

  1. Open the video in the Viewer and the exact frame which the slate hits needs to be traced. The frame timecode should be noted.
  2. Now open the audio file and stop it on the exact frame where the clap of the slate is heard.
  3. Right click on the audio file in the Media Pool and then you need to select ‘Clip Attributes’ and enter the video timecode on the timecode pane.
  4.  sync video audio 2

  5. Now repeat the last step, right click the video and audio files and then select ‘Auto Sync audio based on timecode’ once again.

Method 2: Using Waveform to Sync Video and Audio

  1. Before creating the project you need to transfer all the audio and video files to the same bin in the Media Pool
  2. Now right click the bin containing the selected videos and audios and then choose ‘Auto-sync Audio based on Waveform’ or ‘Auto-sync audio based on waveform and append tracks’. Both the audio and video clip will be analyzed by DaVinci Resolve and matched according to its algorithms just like any other NLE with similar functions.

It needs to be noted here that this method might not work seamlessly on every clip. There is an easy way of checking if the clips are synced or not- just toggle the List mode in DaVinci Resolve and find out the numbers of audio channels present in the video files. You might have to go back and choose the separate clips and audio files and get them synced once again. In case it doesn’t work you need to sync them manually.

Method 3: Manually syncing audio and video

DRV 12.5 comes with an innovative way of navigating clips by making use of audio waveforms. The source viewer comes with a new audio waveform overlay that lets the editor watch the audio waveform and video clip simultaneously. This is surely the quickest way to navigate to any part of the clip.

These are the steps you need to follow for manually syncing audio and video in DaVinci Resolve

  1. Create the project and a bin and import the video and audio files separately.
  2. Now you need to open the audio panel and then scroll downwards till you can find the starting point of the sound.
  3. The audio panel has to be switched from meters to waveform
  4. Now open the Audio Bin and open the audio file which had been captured simultaneously with the video
  5. On the top of the Waveform, the spike in audio representing the starting sound has to be checked. You need to look for the two set in points – 1 for video and 1 for audio and finally click the link icon. Your video will now be synced.
