I create mine in Premier pro: I am not 100% happy with them but they take just seconds to create this way.
I get a few sec clip I am happy with.
<right click> > Field options > Always deinterlace
Export> animated gif
Video setting> frame rate 10
Video Settings> Field Order > Progressive ( this stops the lines issue I had)
Video settings> Aspect > square Pixels (1.0)
Output
Source scaling>Scale to fill
It's not perfect, but then again it only take a a minute or so to create one.
I am not happy with the logo in the gif it is a little blurry, but it works for now
