I set the device format and colorspace to Apple Log and turn off the HDR, why the movie output is still in HDR format rather than ProRes Log? Full runnable demo here: https://github.com/SpaceGrey/ColorSpaceDemo session.sessionPreset = .inputPriority // get the back camera let deviceDiscoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInWideAngleCamera], mediaType: .video, position: .back) backCamera = deviceDiscoverySession.devices.first! try! backCamera.lockForConfiguration() backCamera.automaticallyAdjustsVideoHDREnabled = false backCamera.isVideoHDREnabled = false let formats = backCamera.formats let appleLogFormat = formats.first { format in format.supportedColorSpaces.contains(.appleLog) } print(appleLogFormat!.supportedColorSpaces.contains(.appleLog)) backCamera.activeFormat = appleLogFormat! backCamera.activeColorSpace = .appleLog print("colorspace is Apple Log \(backCamera.activeColorSpace == .appleLog)") backCamera.unlockForConfiguration() do { let input = try AVCaptureDeviceInput(device: backCamera) session.addInput(input) } catch { print(error.localizedDescription) } // add output output = AVCaptureMovieFileOutput() session.addOutput(output) let connection = output.connection(with: .video)! print( output.outputSettings(for: connection) ) /* ["AVVideoWidthKey": 1920, "AVVideoHeightKey": 1080, "AVVideoCodecKey": apch,<----- prores has enabled. "AVVideoCompressionPropertiesKey": { AverageBitRate = 220029696; ExpectedFrameRate = 30; PrepareEncodedSampleBuffersForPaddedWrites = 1; PrioritizeEncodingSpeedOverQuality = 0; RealTime = 1; }] */ previewSource = DefaultPreviewSource(session: session) queue.async { self.session.startRunning() } }
