Best Settings

Narrative Filmmaking

Use the [MOV] file format for maximum editing flexibility. Set the picture profile to [V-Log] to maximize dynamic range for color grading. Use [Manual Exposure Mode] to maintain consistent lighting throughout your scene.

Documentary / Run-and-Gun

Set the recording mode to [P] or [A] for quick adjustments. Enable [Continuous AF] with [Full Area AF] to ensure your subject stays sharp while moving. Use [Auto ISO] with a set upper limit to maintain exposure in changing light.

Interview & Talking Head

Use [Manual Exposure Mode] to lock in your lighting. Set the [Photo Style] to [Standard] or [Natural] for a clean, ready-to-use look. Ensure [Sound Rec Level Disp.] is enabled to monitor your audio levels in real-time.

Slow Motion

Switch to [S&Q] mode. Select a high frame rate (e.g., 60fps or 120fps) and set the recording quality to a high-bitrate [MOV] setting. Note that audio is not recorded in S&Q mode.

Common Issues

Recording Stops Unexpectedly

What's happening: The camera stops recording video before you intend it to. Why: This is often due to the card's writing speed being insufficient for the selected recording quality or the camera reaching a thermal limit. Fix: Ensure you are using a V90-rated SD card for high-bitrate modes. If the camera is overheating, allow it to cool down. Prevention: Use a high-speed card and monitor the thermal management settings.

Autofocus Hunting

What's happening: The camera struggles to lock focus on the subject. Why: This can occur in low-light conditions or when the subject lacks contrast. Fix: Use the [AF Assist Light] in low light or switch to [Manual Focus] with [Focus Peaking] enabled. Prevention: Ensure your subject has sufficient contrast and lighting.

Audio Distortion

What's happening: The recorded audio sounds distorted or crackling. Why: The input levels are set too high, causing clipping. Fix: Adjust the [Sound Rec Level Adj.] to a lower value and enable the [Sound Rec Level Limiter]. Prevention: Always monitor audio levels using headphones before and during recording.
