"A quick question. I got myself some video files at 1080p in .ts and .mkv format, and want to add them to my new iPhone 8. I have VLC, however, it's dropping frames and suggesting the 'puter is too slow. This is possible, but I've had no issue playing other 1080p material ONLY mkv files, Can I convert the MKV to something else? If so, with what?"

iPhone 8 supports 1080p HD video recording and 1080p video playback. After our test with the HD video play back on iPhone 8 we found that there are various ways to play HD videos on iPhone 8. Typically, MP4 1080p video plays fine in Apple Quicktime on iPhone 8. But how about the odd formats such as MKV videos up to 1080p?

About 1080P/720P MKV

MKV (Matroska Video) is a file format for online video distribution. It is an open and free container format which can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. Matroska file types are .MKV for video (with subtitles and audio), .MKA for audio-only files and .MKS for subtitles only. The most common use of .MKV files is to store HD video files.

iPhone 8 supported video formats are:

H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
