OK to be more specific:
when you are in the motion tab…
On the left, are attributes stacked on top of each other.
On the right, are the keyframes for each atrribute.
The keyframes appear in a light grey region, indicating the length of the clip. The dark area on either side of the light grey region indicates whats in front abd behind the clip in the timeline.
Lets say I am editing keyframes for “Scale” attribute. Alot of the time (not always) when I am editing keyframes and moving them around, the light grey region will slip around left and right, so that it has shifted out of line with all the light grey regions below it, which are for the other attributes i.e. crop, opacity etc.
I was just wondering what the reason for this is?
