2: The video file is MP4 but in HEVC codec. My Apple TV doesn't support HEVC codec. It supports MP4 (H.264/MPEG-4). So I need to change the codec to from H.265 to H.264/MPEG-4. Your help is appreciated.

So their relationship is: x265 – H.265 (HEVC), x264 – H.264 (AVC). Talking about converting x265 to MP4, we normally mean converting HEVC/H.265 video to MP4.

Why Convert x265/HEVC/H.265 to MP4?

x265 is judged best overall HEVC encoder specialized in encoding high quality HEVC/H.265 videos. Users can utilize x265 to encode HEVC/H.265 videos which are twice compressed than H.264/x264 videos. To be more specific, to achieve same video quality, x265/HEVC encoding offers double data compression at half bit rate of x264/AVC encoding.

However, taking compatibility into account, H.265 is far less compatible than H.264.
