I’m new to Processing. I was trying to get the code working based on the following link:
> **[transitland/transitland-processing-animation](https://github.com/transitland/transitland-processing-animation)**
>
> Animating scheduled transit trips using the Transitland API and Processing - transitland/transitland-processing-animation
I’m using Linux Ubuntu. The following are the steps to install Processing based on the above link.
```auto
1: Download Processing 3.
2: Download Unfolding Maps version 0.9.9 for Processing 3.
3: Navigate to ~/Documents/Processing/libraries on your machine.
4: Drag and drop the unzipped Unfolding Maps folder into ~/Documents/Processing/libraries.
5: Open Processing, navigate to Sketch > Import Library > Add Libary. Search for "Video Export" and click Install.
6: Quit and re-open Processing.
```
I’m not exactly sure about the step 3 and step 4. More explicitly, how to find the ~/Documents/Processing/libraries folder? I have Processing 3 installed in my home folder. So, I can find ~/Processing folder, and inside of this folder, I have
```auto
devel@hpz4:~/processing$ ls
core install.sh java lib modes processing processing-java revisions.txt tools uninstall.sh
devel@hpz4:~/processing$
```
So, what shall I do then?
I finally choose to use the lib folder. I mean, I drag and drop the unzipped Unfolding Maps into
~/Processing/lib.
Eventually, when I tried the first example following the read me file, the output is as the following.
```auto
devel@hpz4:~/Desktop/python_begin_again/transitland/transitflow$ python2 transitflow.py --name=bart --operator=o-9q9-bart

about above step 2.3.4.

-a- after you installed processing pls
start processing / you are in [JAVA] mode,
run any processing example for test
-b- when you write your own code pls use
file / save as /
> myfirstproject
and it will be saved to a user code area actually you can also change first
after this ( using the path from the picture ) there will be your code at
/home/pi/projects/sketchbook/myfirstproject/myfirstproject.pde
using any filemanager ( here linux mc (midnight commander ) )
you can check on 2 locations:
-a- the user code storage
-b- the processing install path
and there you see that at
/home/pi/projects/sketchbook/
is also that
/home/pi/projects/sketchbook/libraries ( not at the processing install path )
there will be all installed libraries ( actually separated also if you use other MODEs like p5js … )
and that is the path where the unzipped downloaded map tool goes.
after that download unzip to “libraries”
must restart processing IDE
and search examples of that new library and test if it works: like
file / examples / contributed libraries / Unfolding Maps / SimpleMapApp

good, does this work with the examples from “Unfolding Maps”?
now step “5”
i have a problem with this:
> Search for “Video Export” and click Install
there is a library “Video” ( should install anyhow ),
but no specific library “Video Export”
i not know to get from where?

your reply is really really helpful indeed! Yes. You’re right. I think it might be some documentation mistake or processing version updates. I’m working on testing the transitland-processing-aninmation code to see is it works.

Hi, I run it again, and the following is the output.

I finally found the sketch.pde file in the python code directory. And after running it using Processing, I got the following error message:
```auto

ok, thats it

so it was a library video\_export needed.
documentation not wrong, he just not give a link for it.

Yes. That’s right. I finally manually downloaded and installed this library like what we did with the Unfolding Maps library. It worked out charmingly. Thank you again, Kll.

I’m reading the code. I found the template.pde not easy to follow. I’m mainly interested in the animation part. Could you kindly point me to some related tutorial if you happen to know any? Thank you so much for your time and attention!
