Update visualisation example to use ffmpeg instead of moviepy

[bhosale2]

Currently, the continuum snake example in examples/Visualisation uses moveipy for generating videos, unlike other example cases where we use ffmpeg throughout. To maintain consistency, we need to update the example mentioned above to use ffmpeg instead of moviepy.

Hi @armantekinalp, Firstly thank you for responding and assigning me this issue. But I ran into a problem and would like your help.

Before I could implement the solution to the issue, I went ahead and set up my working environment as per Contributing guidelines; and resolved all the dependencies for examples too.

However, when I ran the examples/visualization bash code, the below exception was thrown on the second step

Tracing back I noticed "tid" was not being recognized by Pylance in VS Code:

I tried installing tid manually too, but it returns :

I would really appreciate if you could help me with this. I am using python-3.8.0

Thanks in Advance!
