Say that in your motion project (for an FCPX title) you have:
- a build in section of 60 frames (with build in marker)
- an intermediate section of 60 frames
- a build out section of 60 frames (with build out marker)
Back in FCPX, thanks to the markers, the build in & build out sections have their duration kept constant whatever the length of the title ... EXCEPT when the title length is under 120 frames (sum on the two build in/out sections). What happens then is the build in works as expected and takes 60 frames. Then the build out starts BUT is time stretched in whatever the amount of frames left.
Is there a way to prevent this behavior or at least make it symmetrical between build in & build out ?
Note: using sliders such as "End Offset" that you can sometimes have at your disposal does not work because even though they affect the duration of the build in/out animation, the build in section's length still is of 60 frames (set by the build in maker's position) ... so nothing else ca happen until those 60 frames went by.
It's nearly as what would be needed is a slider to change the build in/out marker's position in FCPX
Moreover, I have another issue with the End Offset parameter of the Sequence Text behavior.
When you change it, the build out duration is shortened, BUT still starts from the build out marker, therefore ending before the end of the project's timeline.
This is not what is usually expected, which is the duration should be shorter but always end at the last frame (i.e. meaning anchoring the right and shortening from the left). The Ramp behavior does that as expected. Not Sequence Text .... unless I am missing something.
Ive just used a horrible workaround: make the title clip longer than required, then keyframe the opacity so that it disappears at the desired end-point (earlier than the duration). This does not answer your original question, and it does not solve all the problems.
