How to fix OBS Audio and Video Sync Issue with a new tool!
Written by Paul Richards on January 15, 2019
The OBS Audio and Video Sync Tool has been designed to answer the important question of how much audio delay an Open Broadcaster Software user should apply in their live streaming system. The tool is a video that combines a visual scale of time with a countdown timer looping in sync with audio blips every second. OBS users can capture a video and audio recording of this tool to accurately determine the amount of audio delay they should apply to their live streaming system to sync up their audio and video streams.
The OBS Audio Video Sync Tool includes a color-coded time scale to quickly measure the amount of time needed to sync your video and audio. The tool also includes an audio syncing bar accurate to one-thousandth of a second. To use this tool you simply need to record the video and audio from the video with the system that you wish to test. This would be your OBS or other video production software with all of the included hardware you are testing. Therefore you will need to record this video with the camera and microphone that you are attempting to sync up. Once this video has been recorded you can import this recording in a video editing software so diagnosis.
Once your recording has been made and imported into your video production software you will be examining the audio section of the recording. Because OBS allows us to delay the audio of our microphone sources, we will be examining the audio sync reading from our video and determining the amount of delay we need to add to our audio sources to sync up our video. Using the video recording you can scrub through the video looking for your audio blips. Generally, the audio will be recorded faster than the video. Therefore you can use the audio sync reading as a guide to adjusting your system. Once you have determined the amount of audio delay your system will require it’s time to apply that audio delay in OBS. You can open up the Advanced Audio Properties in OBS by clicking the settings cog next in the audio section of OBS.
One of the most common issues users have with the OBS software is simply syncing up the audio and video streams coming from multiple pieces of hardware into their live streaming computer. It is possible to sync up audio and video sources “upstream” from your video production software by using a capture device such as a Magewell USB 3.0 pro capture card. In this scenario, the audio, and video by a single device which uses the same drivers to connect to OBS. One of the main culprits with audio and video sync issues is the fact that different products use various drivers with differing latency for conversion.
