Buenos dias
My appologies for intruding and responding in english , but from what I can translate ( babelfish) it seems there is confusion about how the create the video of the dog staying in the screen .

This is done with a specialized program that calculates all these positions inot a videoclip and can also give it as a panoramic picture with the dogs in the same position

if more explenation feel free to contact me through my website (see original post )

regards
Guy
