Getting .mov to work as icons

Re: Changing icons of the modules Current Weather and Weather Forecast

I was reading this old post and when replying it suggested I create a new one.

I am playing with the default weather and forecast modules.

I got my hands on some really nice animated weather icons but they are in .mov format.
I have attempted to convert them to something like .gif but the quality output is terrible.

In the original post @trividar was seeking an answer, not sure if they got it?

Any advice?
