This is a re-encode of the bloated MAYHEM release into the revolutionary HEVC codec for video and OPUS codec (128K) for audio, bringing incredible 720p video at only a ~150MB average for file and 1.4GB for the whole series. Try it for yourself: save some bandwidth and some disk space without sacrificing on quality!
