Importance of audio in video production

Audio can truly make or break a video. Good audio is essential for creating quality videos. You've likely heard the saying, "Oh, we'll fix it in post." In reality, audio is the toughest aspect to fix during post-production. Nailing the audio recording from the start is critical; using the right gear and proper acoustic treatments in your recording environment can save a lot of trouble later.

The role of post-processing in audio

While recording high-quality audio is key, post-processing can help to add an extra layer of polish. Despite taking great care during the recording process, I sometimes use post-processing to enhance vocals, remove background noise, and give audio a little more pop. However, extensive audio editing is unnecessary if the initial recording is high-quality.

Editing audio using Premiere's essential sound panel

When editing audio, I start by making the waveform visible, adjusting the size of tracks to get a good look at the audio. Clicking on Premiere's essential sound panel allows me to confirm that the audio track is dialogue, providing various options for audio mastering.

Techniques for audio enhancement

Noise reduction

I typically begin with a noise reduction setting of around two on a 0 to 10 scale, listening carefully to ensure the changes do not overly alter the original sound.

Dynamics and compression

I apply dynamics, which is essentially audio compression. This subtle adjustment makes soft sounds louder and loud sounds softer, ensuring consistent audio levels.

Equalization

Applying light equalization gives the audio a balanced presence. I choose a vocal presence level of two or three and make adjustments based on the specific needs of the audio. For male voices, I often use a low-tone vocal enhancer.

Adjusting clip volume

After applying these adjustments, I tweak the clip volume to ensure that audio levels remain around -6 dB, which is optimal for YouTube and similar mediums.

Saving audio presets for efficiency

Saving audio settings as presets can drastically reduce editing time in future projects. Creating presets based on specific recording environments ensures consistent quality and speeds up the post-production process. For instance, naming a preset "Aaron's Dallas studio" allows me to apply consistent settings efficiently whenever recording from that particular location.

Post-processing philosophy: less is more

In post-processing, I adhere to a philosophy of subtlety, constantly evaluating and adjusting audio to maintain its natural quality. Heavy processing can make audio sound artificial, so I prefer minimal enhancements.

Wrapping it all up

Presets and a careful approach to post-processing allow us to produce high-quality screencasts swiftly. By maintaining a focus on recording quality audio from the start and enhancing it only as needed, we ensure that our videos look and sound professional. I hope this insight into the process aids your own screencasting endeavors. Embrace the tools available, but remember: less is often more.
