I'm using this code (thanks damikdk) to render lottie animation to video: https://github.com/damikdk/LottieExportDemo/blob/master/LottieExportDemo/ViewController.swift

I'm using the oldExport() in the previous file and these two methods (append and fill) to fill the pixelbuffer with the image: https://github.com/damikdk/LottieExportDemo/blob/master/LottieExportDemo/Helpers.swift

It works great on a iphone 5s and exports 30sec video in approximately 1min. But on a iPhone X it takes up to 10 min to export the same video with the same resolution settings. Is there a way to optimize this to work better on newer devices?

This repository was created as demonstration of bugs, you should not use it even as start point. Sorry if it's not obvious from description.

I am not sure what was wrong in your case, but I will check, if you share your code in issues.

  • Are there any working method to render Lottie as video? – orkenstein Apr 07 '21 at 20:43

    @orkenstein nothing changed since this comment. You can export video frame by frame, but if you want to make it super fast or you are using heavy animations, lottie-ios is not an option – Damik Minnegalimov Apr 08 '21 at 10:31
  • Thanks! What's the key to the frame by frame approach? – orkenstein Apr 08 '21 at 12:46

    @orkenstein try [this](https://github.com/damikdk/LottieExportDemo/blob/c3390aaba0e9b234d70402bf9cde75bdfe679fb8/LottieExportDemo/ViewController.swift#L169) method. 1. set correct progress for AnimationView 2. capture the view 3. write it with assetwriter 4. repeat – Damik Minnegalimov Apr 08 '21 at 14:35
