By default, BlankClip will produce a pitch-black 10 second clip; 24 fps, 640x480, RGB32, with 16 bit, 44100 Hz, mono, silent audio. When supplying a template, BlankClip returns a clip with properties copied from that template. If the template is audio-only, you get a blank audio-only clip, and if it's video-only you get a blank video-only clip.

Float audio is converted to 16 bit when frameserving through ACM, unless OPT_AllowFloatAudio is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.
