How To Sync Audio to Video for Livestreams Using OBS

In this episode we show you how to sync your audio with your video while live streaming. Struggling with misaligned audio and video feeds in your stream? An offset, calculated using your stream’s frame rate, is an easy way to fix that. Let’s take a look at how it’s done!

If you’d like to learn how to make great dialogue audio for your film and video projects, please have a look at my courses including processing dialogue audio in Adobe Audition and DaVinci Resolve/Fairlight, recording sound, how to use the Zoom F4, F6, F8, and F8n, and how to get the most from the Sound Devices MixPre series of recorders. Our latest courses cover Sound for Live Streaming with the ATEM Mini and an Intro to Izotope RX.

Sync Audio to Video in Resolve 18 Using Auto Sync or Manually

In this week’s episode, we demonstrate two ways to sync your separately recorded audio to video clips in DaVinci Resolve 18 for single and multicam video footage. The first method is auto sync based on sound — in this case, Resolve uses the audio recorded by the camera as a reference to sync up the audio from your separate audio recorder. If auto sync fails, and it will for some video formats in Resolve 18, we also demonstrate how to manually sync your audio clips to your video clips.

Timecode Demo with NanoLockit from Ambient Recording

What is timecode and when does it help make things easier for finishing your video or film project? When you’re shooting a project with a LOT of clips and you’re recording your sound separate from camera to get the highest quality sound, syncing can be a lot of work. Using the timecode generators like the Ambient NanoLockit can save you a lot of time. Here’s how it works at a high level.

How to Record Sound for Video: Dual System/Sync Sound

For professionally produced films, the sound is usually recorded separate from the camera by a dedicated audio recorder. Why? Usually, this allows the crew to record higher quality sound. Recording sound this way is called Dual System or Sync Sound. In this episode, we show you how to record dual system sound so that you can increase the overall production value of your video and film projects.
