Long delay to play a .mp4 movie from the Mac

I have a .mp4 movie created from a .mkv file on my Mac. When I try to view it on the Apple TV 4K (from the computer app on the Apple TV) there is a very long delay before it starts playing. Any solution for this?

  • Modify/remux/optimize your MP4 files for Fast Start, so that the meta data is at the beginning of the file instead of at the end. Subler can help with this (and also with the MKV to MP4 part).
  • Make sure your disk with the media files doesn’t sleep when accessed. Waking a hard disk (non-SSD) can take a bit of time.
