Playing HD videos on the iPad (with the retina display) is an amazing experience in itself. All the iPads including iPad Pro, iPad Mini 4, iPad Air 2, etc. are picky at file types such that you can’t import every video to your iPad directly. If you have a lot of .mkv format files (HD video, 720p/1080p), you’ll find that the iPad doesn’t play those. Video content that has AC-3 video (99% of mkv files) aren’t supported directly and you’ll need to use other methods.
Although there have been licensing issues of late, the App Store has quite a lot of apps that let you watch MKV video files without any issues. Note that these apps won’t let you watch DRM-protected content (downloaded from iTunes) but you can watch content that you’ve got synced into your iPad or have on your PC.
