• Apple Got It Wrong: Encoding Specs for HEVC in HLS - Adding HEVC to your HLS streams is looking like a no brainer, but if you decide to do so, you may not want to take Apple's HEVC encoding recommendations verbatim. You'll deliver noticeably higher quality video if you follow the advice detailed below.

• Guide to HEVC/H.265 Encoding and Playback - HEVC's main advantage over H.264 is that it offers roughly double the compression ratio for the same quality. This means that a video file encoded with HEVC can occupy half the space of its H.264 equivalent with no noticeable change in quality, or the same amount of space with improved quality.
