How to Configure Interview Audio in Blackmagic Camera on iPhone

Before you begin: Blackmagic Camera for iOS. Screenshots: version 3.5.20 on iPhone 14 Pro Max. Start from your preferred baseline; changing these settings affects subsequent recordings.

Open Blackmagic Camera on your iPhone. Start in the Camera view. This walkthrough uses version 3.5.20 on an iPhone 14 Pro Max; available formats may differ on other devices.

Tap Settings at the bottom. The recording, camera, audio and monitoring settings appear in this scrollable list.

In Settings, tap Audio Source.

Select the iPhone microphone for this example. An external microphone requires its own source selection and connection check.

In Settings, tap Audio Format.

Choose Linear PCM for this audio workflow. Check compatibility with your editing software.

In Settings, tap Sample Rate.

Choose 48 kHz. Before an interview, make a short test and listen for noise, distortion and the speaker’s distance from the microphone.

Return to Camera and check your framing, lighting and sound before recording. The screenshots demonstrate settings; they do not include a recorded clip.
