Recorder Configuration

VideoKit Recorder allows to adjust the recording quality of your video clips.

Video and Audio Configuration

Using VKRecorderViewController

In order to change the recorder configuration of VKRecorderViewController, go ahead and extend your custom Recorder with VKRecorderViewController and set up the view controller delegate.

Then, in your view controller, you are able to change the video configuration in the delegate method configure(video: VKRecorderVideoConfiguration, audio: VKRecorderAudioConfiguration)

RecorderViewController.swift

import VideoKitRecorder
import AVFoundation

extension RecorderViewController: VKRecorderViewControllerDelegate {
    
    func configure(video: VKRecorderVideoConfiguration, audio: VKRecorderAudioConfiguration) {
        vkRecorder.frameRate = 30
        
        video.bitRate = 6000000
        video.maxKeyFrameInterval = 30
        video.aspectRatio = .tiktok
        video.dimensions = CGSize(width: 1080, height: 1920)
        video.scalingMode = AVVideoScalingModeResizeAspect
        video.codec = AVVideoCodecType.hevc
        video.preset = .high
        
        audio.bitRate = 44000
        audio.channelsCount = 2
    }
    
}

Using VKRecorder

If you are using VKRecorder and implement your own ViewController, you can directly access the public properties videoConfiguration as well as audioConfiguration:

MyCustomRecorderViewController.swift

import VideoKitRecorder

extension MyCustomRecorderViewController: UIViewController {
    
    func viewDidLoad() {
        VKRecorder.shared.frameRate = 30
        
        VKRecorder.shared.videoConfiguration.bitRate = 6000000
        VKRecorder.shared.videoConfiguration.maxKeyFrameInterval = 30
        VKRecorder.shared.videoConfiguration.aspectRatio = .tiktok
        VKRecorder.shared.videoConfiguration.dimensions = CGSize(width: 1080, height: 1920)
        VKRecorder.shared.videoConfiguration.scalingMode = AVVideoScalingModeResizeAspect
        VKRecorder.shared.videoConfiguration.codec = AVVideoCodecType.hevc
        VKRecorder.shared.videoConfiguration.preset = .high
        
        VKRecorder.shared.audioConfiguration.bitRate = 44000
        VKRecorder.shared.audioConfiguration.channelsCount = 2
    }
    
}
