UIImage to movie using metal

Question

I know how to export UIImage array as a movie using swift. But it takes a lot of time. I am following this thread How do I export UIImage array as a movie?

Is there any way to reduce export time? I am trying to export UIImage array as movie using metal to check if it can reduce export time. But I am not getting any resource to do that. Any kind of help is appreciated.
