    I have a dozen of 4K movies while lots of my movie connection is HD. Maybe I need a professional 4K video to convert my 4K videos. But in most cases, I probably need it to convert my 1080p, 720p videos to play them on my iPad. Does this 4K video converter can convert MP4 1080P videos to AVI 1080p videos?
