Handbrake Preset for 480p Handheld Consoles

This is a Handbrake preset designed with cheap emulation handhelds (640x480p screen, mono speaker) in mind, including but not limited to the Anbernic RG-35XX family and the Miyoo Mini/A30, as these usually feature built-in media player apps.

We are using H.264 video (for best compatibility and CPU load) encoded with a CRF value of 19 for good compression to quality ratio, however this can be changed by the user as they wish. (higher RF = higher compression, lower RF = higher quality) Opus audio is being used as it is the most efficient codec at the bitrate set (64kbps per channel is near-transparent) without having to compile Handbrake with support for Fraunhofer's AAC encoder for HE-AAC

Some additional settings are enabled that can be changed by the user:

• Tune: defaults to None, however I recommend Film for live-action and realistic CGI content (i.e. Transformers), or Animation for 2D animation and less realistic CGI content (i.e. Toy Story and other earlier majority-CGI films)
• Deinterlace filter: only use this for interlaced content, you may disable it if you wish to spare encoding time on progressive scan content
