On the gopro, the frequency that's making jello is only handled by really soft materials. silicones like mask type or foam like ear plugs. on a stock frame it's hard to fit, but on a custom frame, is why it's custom...... guess a guy could make a platform and the base mounted to a stock frame somehow
makes this with pretty much any prop from what i'm told. mine were new unballanced graupner 9x5
that's all raw gopro and video capture footage, no post stabilizing
