Aspect is combined aspect ratio, frame size and avi bitrate calculator. It can:- calculate frame size according given aspect ratio- evaluate aspect errors- check frame size for compliance with codec (i.e. ensures that frame height/width is multiple of 4, 16, etc.)- calculate aspect ratio according given frame size- calculate avi video bitrate/size and bits/pixel value- automatically calculate frame size- evaluate interleave overhead for legacy and opendml AVIs- adjust aspect ratio for cropped movies- access unencrypted vob, mpeg2, d2v, png and bmp files-retrieve video resolution, aspect ratio, fps and duration from supported video files- show frame preview- generate avisynth scripts out of d2v files
