Motion track crack on the wall in After Effects

Hello, there!


I'm making a video about risk areas in slums and I did some animated lines to reinforce what the interviewee is talking about.


I lined some pipes, garbage and street light using motion track with no problem.


However, I have a scene where the camera follows a huge crack on the wall, and I want to make a line that follows this crack.


The problem is that the start point and the ending point of the camera don't have any commom point that I can track.


I’ve already tried to do it frame to frame, but the result sucks.


Can anyone help me, please.


Here is the link of the footage:
