I've happily used Handbrake to encode in Apple TV format, and iFlicks 2 to encode the metadata into my iTunes content for years. With the ATV4K I have tried modifying the Handbrake preset for the ATV3 to use h.265 and setting the max video size to 3480x2160 which (eventually!) gives a file that should work on the ATV4K. The problem comes when I try to update the metadata as iFlicks 2 forces a re-encoding back to 1920x1080 which kind of defeats the purpose of this. 1) Anyone found a decent metadata editor that works with h.265 encoded 4K content correctly? 2) Anyone have recommended settings for Handbrake for the ATV4K?
