unfortunately there is no tacking or pinning feet to the ground in daz studio when using ani blocks which is what i use to make that gif with . I did it in 5 rendered scenes and just looped them. in premiere pro and export the movie loop as Gif instead  swf or MOV . that is one of the bad things about Using daz studio there is no character floor lock or pinning.among a few other limitations.

In Maya & 3DS Maz they have a floor pinning that you can set the floor level settings as your hard surface and then set the character to the floor level.unfortunately I don't have the full version just the student version of autodesk.

I have not tried it in Poser pro.2014 .  I hardly use poser any more. properly because of the compatibility issues between daz studio and poser. pro  with the new genesis 2 & 3 characters . the girl in the twerking scene was genesis 2 female. 

when daz was just using Generation 4 characters it was effortless to interchange between poser and daz when making a animation. now days not so much. so I pretty much have stuck with daz mostly because i can render real time  using Iray with my Nivda graphics cards  which had been a ton of help  catching the flaws before I render the final scene. so that is been a plus.
