Recording Separate Audio for Church Production

-

It is often said that half of great video is great audio. It is certainly true that bad audio can kill good video. But it’s not always easy to get great audio into your camera every single time. While it can be tricky, the dividends will pay off when the audio is high quality and is synced perfectly to the video. Whether you’re producing a delayed livestream, captured video church service for YouTube, or some other video church production, spending time on the quality of the audio is important.

Why Separate Audio?

Why would you need separate audio? If your camera doesn’t have a high quality audio input (XLR inputs), you may want to consider recording audio separately. But what if you want to record more than two separate tracks of audio, like if you have four people on camera? Even higher end cameras only have two microphone inputs. You can mix their signals into one (or two), but then you lose the ability to adjust individual levels in post. In this case, it would be great to record audio separate from the camera and add it into your video when you edit.

Additionally, you may need to roam around a room but you want to get audio from the band on stage. In this scenario, you may want to record the output from the sound board to get a nice mix of the band and add it to the video in post. There are plenty of scenarios you may encounter that require separate audio recording. So, how do you accomplish separate audio recording without sacrificing quality?

 

Where To Start?

Fortunately, recording and syncing separate audio for video is easier than it has ever been. To get great results, you must prepare before you shoot. First, you will need a good quality audio recorder. It could be a computer, a multi-track recorder in your sound booth or a recorder designed for video production (see some recommendations at the end).

Second, make sure you can record a scratch track on the camera. Ideally, you will keep your camera microphone on or send a mixdown feed to your camera in addition to recording your tracks on a separate recorder. You’ll see why this is important in a moment.

Finally, make sure you have a reference in order to sync the sound. Some recorders allow you to sync timecode on both the camera and recorder, but this is often only available on high end equipment. The best way is to use a clapper or something similar. You’ve probably seen these, they are the sticks clapped together before a scene in a movie. The reason for this is to create a distinct visual and audio cue that will tell you where to line up the clap sound on the audio track with the visual of the sticks coming together on the video track. If you get this right, the rest of your track will sync perfectly. But you don’t need a fancy clap board, you can just use your hands. Have someone on camera clap into the microphone while you are filming them…done. In the event that you are not able to sync at the beginning, try syncing at the end of your recording. If you can’t sync at all, there is still hope. Read on.

 

Fix It In Post

Once you get your video and audio in your editing software, its time to sync. Remember I told you its a good idea to record a scratch track on your camera even if you are doing a separate recording? Now is where that will help you immensely. By listening to the recorded track and the scratch track together, you can sync your audio by ear. You can adjust your audio track to the left or right on your editing timeline to get it to match the scratch track. Once you are close, mute your scratch track and do the rest by eye, making sure the mouths, drum hits and other percussive visuals sync up perfectly.

But you don’t have to do everything manually. PluralEyes is an app that lets you input your video and audio. It will analyze the audio information on your scratch track and the separate recording and sync them. Adobe Premiere has syncing ability built into the application.

By taking time to give attention to the quality of the audio and syncing it with your church video production, you can be sure people will notice the attention to detail (or rather will not notice the lack of attention to detail). They will be free to engage with your church through video as one of the many ways your church is able to reach people for Christ.
