Video background noise

Hi,

I am merging 2 3 videos, final merged video contains some background noise in it,
Please update, is there a way to remove noise?
I was thinking that there might be some issue with UIIMagePickerController.
But it's the final video that contains noise.

@Shahriyar98 Your videos have sound or not? If possible, could you upload your videos here?

@khoavd-dev Noise was resolved it was video player issue. But now there is another issue, download the videos available at below link. Place these videos in your demo project and then pass the array off URLs to your code. Video merging is not smooth, there is a black screen before start of next clip in the merged video. Please have a look at this.
