Video Settings

• Resolution: 4K 50/30fps, 2.5K 50fps, 2.5K 48/30(4:3)fps, 1080p 50fps, 1080p 30fps. Higher frame rates provide smoother TV output; 50fps is recommended for FPV. Note: 4K 50FPS cannot log gyro data.
• Loop Recording: Off, 1, 3 minutes. When the SD card is full, the oldest file will be deleted first for continuous recording.
• WDR (Wide Dynamic Range): Off, On. Enables the camera to capture clearer images in bright light conditions, even when facing the sun. It may sometimes reduce image clarity. Recommended to be ON for FPV cameras.
• Exposure: Adjusts image brightness. Higher values result in a brighter image; lower values reduce overexposure. Options range from -2.0 to +2.0.
• Record Audio: Off, On.
• Date Stamp: Off, On. Adds date and time stamps to videos.
• Time-lapse Record: Off, 0.05, 0.1, 0.5, 1, 3, 5, 10, 30, 60 sec. Records video at a low frame rate (1-2 fps) for time-lapse effect. Higher values result in shorter videos. No audio is recorded in this mode.
• Slow Motion: Off, 720P 120. Enables slow-motion video playback.
• Metering: Average, Center-weighted, Spot. Determines how the camera measures light for exposure.
• Sharpness: Strong, Normal, Soft. Adjusts image sharpness.
• Contrast: High, Medium, Low. Adjusts image contrast.
• Auto Recording: Off, On. The camera automatically turns on and records. If power is cut unexpectedly or recording is not stopped properly, the file may be damaged and repaired automatically upon playback using the keyboard.
• Gyro Log: Off, On. Saves gyro data for image stabilization on a PC.
• Gyro Calibration: Place the camera horizontally, keep it still, and press the OK button to start calibration.
• Snapshot in Recording: Off, 5, 10, 30 sec. Allows taking photos while recording video.
