When I export video files (e.g. MP4) from LR5, no meta data is written to the files when I expect at least the year and title to be written.
Files like mp4, m4v and mov all have well documented meta data fields. Why doesn't LR support this?
LR's support for video is incomplete. Please see and vote on this topic in the official feedback forum:
