Ich versuche mit ffmpeg einen komplexen Effekt zu erzielen, aber ich versuche, die Syntax von -filtercomplex irgendwo zu versagen.The -2 is to tell the scaler to scale to a even number as some formats do not support a odd number of pixels

scale=-2:360 and scale=-2:720 scales the input to 360px and 720pxheight respectively while preserving aspect ratio and sends the output back to the same input name.

split=2: Split the stream into 2 and store them as 360pand 720p.

In a sense, this gem is really a 'string factory', as its main output is a single string you can pass as the argument to ffmpeg s -filtercomplex command-line argument.
