How to Load H.265 (HEVC) Videos to iTunes on Windows?

In order to enjoy the H.265/HEVC movies, some users would like to use iTunes to manage their videos in local on Mac devices, but how can they transfer H.265/HEVC videos into iTunes to watch smoothly on Windows 8.1? May be converting H.265/HEVC to MP4 could be the best solution, do you think so?
