An easy-to-use utility for merging photos to into a video, written in Swift.

  • Support iOS 8, Swift 1.2, xCode6.3.
  • Singleton pattern, just few lines of code for using.
  • Can compose Photos into a video file with a background music.
  • Customized CALayer Animation can been exported into a video file.


Create your own CAAnimation, and pass it to WSDynamicAlbumMaker.

let videoURL = NSURL.fileURLWithPath(NSBundle.mainBundle().pathForResource("BaseVideo", ofType: "m4v")!)    //  1
let audioURL = NSURL.fileURLWithPath(NSBundle.mainBundle().pathForResource("music", ofType: "mp3")!)        // *2 

let renderLayerSize = WSDynamicAlbumMaker.sharedInstance.querySizeWithAssetURL(videoURL: videoURL!)         // *3
let albumLayer = createSequenceAlbumCALayer(renderLayerSize)                                                //  4
let duration = 10                                                                                           //  5

WSDynamicAlbumMaker.sharedInstance.createDynamicAlbum(videoURL: videoURL!, renderLayer: albumLayer, duration: duration, completionBlock: { (url, error) -> Void in
    if let err = error {
        // error accured during exporting
    } else {
        // export DONE!
        // you can do more with the *url*

In the Code :

  1. Prepare a 1s-length-video, just used as a canvas to draw CAAnimations on, so really don’t care about the video’s content.
  2. Choose the background music. (also you can ignore it, to create a silent video)
  3. Ask WSDynamicAlbumMaker for the size of the rendering video which you create in setp 1, and you can make your animation based on the Size.
  4. Create a CALayer instance, with all animation setted up, this CALayer instance will be persistented into a video file.
  5. Point out the Animation’s duration.
  6. Go create the Dynamic Album, WSDynamicAlbumMaker will generate a video with the content of the animations in the CALayer instance .
