the initial mkv file can be burned as a Blu-ray image to a single or double-layer DVD-R. The mkv file accompanying this kind of release is 200–300MB smaller than a similar release following the other ruleset due to the overhead of the Blu-ray image that will be created. Around May 2012, the stream of BD9 releases came to a halt. 2011 only had around thirty BD5 releases. x264 for anime On August 13, 2009, the first version of the standard was released. This standard is only a recommendation for anime from Blu-ray and its purpose is to improve quality over the then current HDX standard.
