Tips on VSE

Hi guys, I´ve got an editing job, I have a few videos to import and place an animation on the beggining and end of each video I´m doing as this:


The two selected strips are the motions that are going to be used for every video, the problem is at the end, since every video has a different duration I have to manually copy and insert the video in the end of every strip, that wont be a problem if I have a 5 videos, but for 120 videos I´m getting boring, also the motion stripes could be changed by the client so if they change a detail there I have to manually again update.
