Add automatic wipe to a clip make it's not possible to add another one.
now, the automatic wipe effect is again available (but the flag on CLIP MENU is obscured yet), and it's possible to add a wipe to a clip for the entirely lenght... but if i reduce the wipe lenght is not possible to add a 2nd wipe effect from the opposite corner (this feature works on 19.04 and 19.08)
maybe the automatic wipe effect is bugged and use the entire size of the clip (and not only 2/3 seconds)
BTW .. here a video about this: rnSjNQbQZ1
