I followed this tutorial to change the length of a matinee:
which says: “After zooming, you’ll notice two red tabs in the lower part of the timeline. These represent the length of the Matinee sequence. At the moment, they are positioned at 0.00 and 5.00 so this Matinee is 5 seconds long. You can change the length by grabbing the red tab on the far right and dragging it to the length you want your Matinee to be.”
I think it worked in the past, but now when grabbing the red tab, it will just disappear, or snap to 0 seconds.
Can confirm this bug for 4.9.2. Cannot change length, it just instantly snaps to 0 (Snap setting is 0.1). After then, it doesn’t react at all anymore to clicks.
