De-noising effect not visible

[wico-heuschkel]

I tried to use the model to denoise an analog video feed. The results are not convincing, in fact I don't see any difference between noisy and denoised images. Are the additional steps to take to improve the performance?

Here one example

Another example

As the images before and after are fine (without the noise lines), I was expecting that the temporal denoising removes these lines. Is this a wrong expectation?
