During the Quidditch match as the players ride their broomsticks, visible in quite a few shots are the two WIRES that are attached to the broom handle, between their legs, that extend down with a clamped loop that goes around their feet. In some shots the wires between their legs are edited, but the wire loops around their feet are perfectly visible, like in the following example. When the Slytherin score hits 10 onscreen, in the next shot, as Flint shouts, "Take that side," the wire is completely visible at his right foot under his cloak. Two examples where the entire wires are visible are, when Flint grabs the club and says, "Gimme that!" the wires are blatantly visible and he then proceeds to slam the Bludger into Wood, who falls. Next close-up of one of the twins, the wires are clearly visible before Flint starts to leap over him. (Don't confuse the cloak's long front ties for the wire.)
