Two conditions are required. The keyframe to which time is added
• Must exist within the slide time,
• Is the last keyframe on all layers before the start of the transition out.
Further, that keyframe must have at least 0.001 seconds of space between it and the start of the transition out region. That’s because, as given above, time is added to the right of the keyframe AND is added to the region in which the keyframe exists.
Now, add the desired amount of time.
The assumption here is that the excess/unnecessary time exists at the end of a slide. Therefore, removed time must come from the right side of last keyframe (on any layer) (NOTE: see the Important Note above).
Remove the slide’s extra time as given above.
If necessary, add a keyframe at the point that will become the end of the slide and delete the desired amount of time. Then, delete that keyframe (if it’s no longer needed).
