Fixed version for ffmpeg (aspect ratio auto calculation works now with non ususal aspect ratios, overall flexibility improved, new: anti-aliasing* added - optional, improved audio syntax, still issues with color space - ffmpeg ignore (partially?) syntax and seem that issue is raised on ffmpeg bug-list - solution for today: piping - perhaps in next version)

@rem echo --audio--
@rem possible samplerates are for example: 28604, 23646, 22168, 15977, 11260
@set samplerate=15977

@rem possible ngain are for example: -3.0103, -6.0206, -9.0309
@set ngain=-6.0206

@rem possible audither are: 0,1,2,3
@set audither=1

@rem possible volume value are for example: 3.0103dB, 6.0206dB, 9.0309dB, 12.0412dB, 18.0618dB or 1.5 2 etc
@set avol=1

@rem echo --video--
@rem possible vidither are: 0,1,2,3,4,5,6 or "bayer","ed","a_dither", "x_dither"
@set vidither=bayer
@rem possible video color space are: rgb555le (15 bit), rgb444le (12 bit - native Amiga) ;CLUT format not suitable for AVI conatiner but fine GIF (or similar format) bgr4_byte (4 bit CLUT), rgb8 (8 bit CLUT) 
@set cspc=rgb555le

*AA implemented as hqx - slower, not universal, but improvements visible - to turn ON - un-rem second ffmpeg.

Automatic Audio can't be implemented currently without at least 2 pass or pipe - perhaps in future sufficient filter for ffmpeg can be used to do this.
