Baka Encoder is a self-contained x264, x265 and NeroAAC frontend dedicated for producing final encodings of video materials.

Handles AviSynth scripts, video/audio without compression and video compressed with common intermediate codecs. Presets are defined via XML config with direct control over x264, x265 and NeroAAC command line parameters.
