Regardless of aspect ratio, at some point your speed selection is limited
because the patch gets too small. That's why with Meta-Speed, for example,
you can't select most speeds between 30 and 40 fps on a MKIII. The inverted
scan with the flip allows the Gold more usable sizes and speeds, and it is
useful for Super-16. There is a feature in development for the
Quattroscan in conjunction with Meta-Speed which will give you
continuously variable speed. IE, you could dial in a speed, the
machine would just do it, and the patch would be ok. This will remedy
limitations imposed by the present method of counting vertical intervals
to determine valid speeds.
