I want to apply filter to the video like tiktok app. for example If my video is 1 min long then I want to apply one filter till 30 second and another filter till 30 sec so I need two filter effects for 1min long video.

Using following Code I have applied one static filter effect to whole video via GPUImage

import UIKit

import GPUImage



class ViewController: UIViewController {



    @IBOutlet weak var renderView: RenderView!



    var movie:MovieInput!

    var filter:SketchFilter!



    override func viewDidLayoutSubviews() {

        super.viewDidLayoutSubviews()



        let bundleURL = Bundle.main.resourceURL!

        let movieURL = URL(string:"Jelly.3gp", relativeTo:bundleURL)!



        do {

            movie = try MovieInput(url:movieURL, playAtActualSpeed:true)

            filter = SketchFilter()

            movie --> filter --> renderView

            movie.runBenchmark = true

            movie.start()

        } catch {

            print("Couldn't process movie with error: (error)")

        }



     }

 }

How can I get video Range or anything which help me to achieve this?

Thank you!
