AVCaptureSessionPresetPhoto

Specifies capture settings suitable for high resolution photo quality output.

AVCaptureSessionPresetHigh

Specifies capture settings suitable for high quality video and audio output.

AVCaptureSessionPresetMedium

Specifies capture settings suitable for output video and audio bitrates suitable for sharing over WiFi.

AVCaptureSessionPresetLow

Specifies capture settings suitable for output video and audio bitrates suitable for sharing over 3G.

AVCaptureSessionPreset352x288

Specifies capture settings suitable for CIF quality (352x288 pixel) video output.

AVCaptureSessionPreset640x480

Specifies capture settings suitable for VGA quality (640x480 pixel) video output.

AVCaptureSessionPreset1280x720

Specifies capture settings suitable for 720p quality (1280x720 pixel) video output.

AVCaptureSessionPreset1920x1080

Specifies capture settings suitable for 1080p quality (1920x1080 pixel) video output.

AVCaptureSessionPresetiFrame960x540

Specifies capture settings to achieve 960x540 quality iFrame H.264 video at about 30 Mbits/sec with AAC audio.
QuickTime movies captured in iFrame format are optimal for editing applications.

AVCaptureSessionPresetiFrame1280x720

Specifies capture settings to achieve 1280x720 quality iFrame H.264 video at about 40 Mbits/sec with AAC audio.
QuickTime movies captured in iFrame format are optimal for editing applications.

AVCaptureSessionPresetInputPriority

Specifies that the capture session does not control audio and video output settings.
To enable capture settings not supported by any session presets (such as high frame rate), change the value of the activeFormat property on the appropriate capture device. When you change the device’s format, the session preset automatically changes to this value, indicating that the AVCaptureSession object has relinquished responsibility for configuring its inputs and outputs. (Instead, the capture device’s active format dictates the quality of service level provided at the outputs.) To return to automatic configuration, use the session’s sessionPreset property to choose another preset.
