Part 3: Best Practices to Match Audio to Videos

The following are some tips that will help you match audio to video in less time.

      • Use a clapboard – Now, you will understand why the filmmakers use a clapboard to record a movie. This is the simplest method to synchronize sound with video. The sound of the clap becomes the reference point to match the audio with the video.
      • Record audio on an external mic and your camera— Just because you use an external mic doesn't mean you shouldn't use your camera microphone to record the audio. In fact, when you have audio from both sources, it'll save a lot of time matching the audio.
      • Be attentive to the waveforms— While editing the audio and video, pay attention to the audio waveforms and the spikes. If you are not using the clapboards, there could be some other sound in the video, such as a cough, sneeze, etc., that forms spikes in the waveform. These can be used as a reference point to sync audio and video.

Conclusion

If you have only a single audio file to match to a single video file, using a clapboard or observing the audio waveform spikes could help in video synchronization. However, if multiple audio and video files need to be edited, it is best advised to use auto-syncing software.

Thankfully, we have discussed 5 different video and audio synchronization software in this article and offer steps by steps guide for each. If you are looking to record new audio to sync videos, or directly trim the unnecessary parts to match, you can try our AI-powered Wondershare Democreator.
