To Data

VideoEditor SDK supports saving videos to a Data object.

For the sake of this example, we create a video from a URL and present the video editor in a modal. Note, that we have to make the current class the delegate of the VideoEditViewController in order to handle export and cancellation there.

Implementing the Video Export Delegate Method#

When a video export is successful the method videoEditViewControllerDidFinish is invoked on the delegate class and a VideoEditorResult object is passed as an argument.

If no modifications have been made to the original video, we will not process the original video at all and also not reencode it. In this case, result.output.url will point to the original video that was passed to the editor, if available.

If you want to ensure that the original video is always reencoded, even if no modifications have been made to it, you can set VideoEditViewControllerOptions.forceExport to true, in which case result.output.url will always point to a newly generated video.

Load Video into Memory#

We create a Data object from this url passing it as contentsOf argument to the constructor. Note that video file sizes can be large and loading them into memory might not be possible.

Once you are done processing this data, we recommend that you delete the temporary file. Here, we first check whether the video file was passed without changes. This check is only necessary when working with the Simulator, since in production the app bundle is read-only.
