How To Create Animated GIFs for ADS?

Guys,

I am new to cpa adult world but wish to create some ADS that are animated. I know there is software and sites to create GIFS from Videos, but how do i create a gif for a few seconds from a video?

Take this gif for example.

Please note, its not my AD, so if mod wants it down, please take it down.

The GIF is a couple of seconds on a loop. How would i extract a couple seconds from a vid and make a gif? Then once i have the gif, how would i make a ad out of this with text etc?

Any help would be great, thanks

would mind removing that picture? Looks too sexy.

Secondly, photoshop+Aftereffects can do it. Quick 5 mins job.
