you will have to do like following to resolve this issue.

        if let limitFPS = config.limitFPS {
            videoComposition.frameDuration = CMTime(value: 1, timescale: limitFPS)
        } else {
            let rate = try await videoTrack.load(.nominalFrameRate)
            videoComposition.frameDuration = CMTimeMake(value: 1, timescale: Int32(rate))
        }
