How to move/remove/join adjacent Blade Speed points in FCPX So, the Blade Speed retiming tool in FCPX is half-awesome.

But once I have put a blade marker in I can't work out how to:


remove it (apart from immediate undo, i.e. later on)
move its position in relation to the src clip, i.e. I put the blade point in the wrong place, I want to move it without adjusting the retiming either side of the point
join adjacent retimed segments... related to above, if I put in a new blade point in the correct position I can't remove the wrong one (1) or see a way to join/merge the adjacent retiming segments
Partial answer...

I still don't know how to remove a single blade speed point.  It is possible to remove all speed points for a clip by selecting the clip and choosing a new speed (eg Normal 100%) from the Retiming menu.

I still don't know how to join adjacent segments (kind of same thing as above).

Found out how to move the blade speed point relative to the clip itself without retiming:


double-click the blade speed centre handle and click the 'Edit' button





You get this icon you can drag in the timeline:




(classic bit of Apple "hidden UI" gotcha)

If you are zoomed in and you have a big speed differential either side of the centre point then it may not be at all obvious that you really are moving the src frame (fooled me before) because the preview changes are complex. But with Normal speed both sides it is clear this does what I wanted.
