Very stable with the following values:
(need_for_speed)
? ((queued_frames > valid_slot_count / 2) ? 416 : 208)
: 20
(I chose multiples of 24/1000) .0416
Pushing it much harder produces slot error when buffer is full and recording stops (5d3.123)
I would like to discuss cleanest way to implement as a menu option, (and what to call it) I like the behavior when Gray Ultrafast is used full time, but pressing halfshutter switches to realtime (5x) almost like a magic zoom) I honestly think the color half-res preview is useless.
