Audio Syncing Issues

Out of sync audio and video is one of the most common hurdles in video content creation. The problem can arise from various factors, including limitations in recording equipment, technical glitches, or even human error. But regardless of the cause, the result is the same—a frustrating viewing experience for the audience.

In this article, we’ll talk about ways to avoid audio syncing issues when using a microphone with Sony A7C. By addressing the challenge of out-of-sync audio and video, content creators can deliver high-quality videos that engage, captivate, and leave a lasting impact on their viewers. 

Choose a Compatible Microphone

Different recording scenarios require different types of microphones. By choosing a compatible microphone, you not only prevent audio syncing issues but also gain access to a wider range of audio options to suit specific recording needs. 

Microphones designed for DSLR cameras come in many types, including shotgun microphones for capturing directional sound, lavalier microphones for hands-free recording, and stereo microphones for creating immersive audio experiences.

They usually feature the appropriate connector, such as a 3.5mm audio jack or a dedicated hot shoe mount, making it easier to connect and stabilize the microphone on your Sony A7C.

Test and Monitor Audio Levels

When the audio levels are inaccurately calibrated or off, it can result in disruptive audio syncing problems.

Especially when you’re working with multiple cameras and recorders, each one might have different audio levels and settings. So, it’s important to consistently test and monitor the audio levels to maintain synchronization across all sources. 

Maintaining optimal audio quality is another reason why testing and monitoring audio levels is important. When you keep those levels in the right range, you can avoid issues like audio clipping, distortion, or barely audible recordings.

Record Shorter Segments

When the recording duration is shorter, the chances of noticeable sync discrepancies are significantly reduced. This is particularly crucial in situations that require precise synchronization, such as interviews, dialogue-driven scenes, or any content where audio-visual coherence is paramount.

Recording shorter segments also offers greater flexibility during the editing phase. If you encounter audio quality or syncing issues in a specific segment, you can easily isolate and address that section without affecting the rest of the recording.

Invest in Software like Syncaila

Syncaila is a specialized tool designed to automate the process of synchronizing video and audio footage from multiple cameras and recorders. It aims to save time and energy for video editors by eliminating the need for manual synchronization and allowing them to focus on more creative editing tasks.

With Syncaila, video editors can sync footage from different sources without relying on traditional timecode references. By automatically analyzing the audio and video tracks, Syncaila can significantly streamline the editing workflow. 

Don’t Record Audio Directly Into a Computer

Recording audio directly into a computer without a video feed can cause syncing issues unless it’s for specific situations like last-minute voiceover tracks. 

To make sure everything syncs up seamlessly, capture audio and video at the same time whenever you can. That way, both elements are recorded together, and you won’t have to deal with complex syncing processes later.

FAQS about audio syncing issues

What Is the Disadvantage of Using a Camera’s Built-in Microphone?

Built-in microphones generally offer lower audio quality compared to dedicated external microphones. They are designed to capture a wide range of sounds within their limited space and are often located near the camera’s body, making them prone to catching unwanted noise such as handling, wind, or autofocus motor noise.

What Causes Audio Sync Drift?

Audio sync drift can be caused by various factors, including:
Clock speed differences – This is more likely to occur when using separate devices for audio and video playback or when using devices from different manufacturers.
Encoding and decoding processes – During the encoding and decoding processes, audio and video signals may undergo different processing delays, leading to audio sync drift. 
Variable frame rates – Variable frame rates can occur when recording gameplay, screen captures, or videos from certain devices. The inconsistency in frame rates can result in audio and video gradually going out of sync.
Hardware limitations – Some older or less powerful audio or video playback devices may struggle to maintain perfect synchronization between audio and video. 

How Do I Know If My Microphone Is Working Properly?

Access the audio settings menu on your DSLR camera and make sure the microphone is selected as the audio input source. Then, start recording a short video clip while speaking to check if the audio is clear and audible. 

How Do I Use an External Microphone With My DSLR?

Simply plug the cable of your external microphone into the microphone input jack on your DSLR camera. For a 3.5mm connection, insert it into the corresponding port. If using an XLR microphone, you may need an XLR-to-3.5mm adapter or an XLR-to-XLR cable.
