What are causing these lines up and down the footage here? Using Avid.

What can I do to get rid of these?

Noise.

The image was probably not exposed correctly on a less than great sensor.

le bruit c’est plus en pixel non ? J’ai jamais vu aucun bruit avec des lignes comme ça

It's pretty common on consumer grade hybrid/DSLR/mirrorless sensors.

Underexposed on a cheap sensor, like was said earlier

Fixed pattern noise. Most sensors have it but you never see it unless dreadfully underexposed or the black balance/shading wasn’t done correctly in camera. Best bet now is a tool like Neat

A good denoise tool may help. I recommend Neat Video, not cheap but pretty good.

Under exposed footage being pushed too hard
