You are suggesting that some of the clips on clips4sale showing "underwater head holding to the point of going out" . . . are fabrications?

Well . . . I am a fan of KPOP and there is one KPOP song which has a music video showing what appears to be a magic act. And part of the music video shows one of the KPOP dancers being dunked into a pool of water. Tis fun, but one day I actually looked at the length of the segments showing her underwater and added them, which came to about 45 seconds . . . which tends to be fairly normally doable by most people.

And yes, some of the clips showing underwater head holding or being underwater splice in and out with different camera angles, and so they are showing you seconds of the same thing.

But some of them do not . . . Now they could be frauds and fabrications . . . I simply do not think so, yet!

You think that zero of the clips of head-holding at clips4sale, with the depiction of going out are genuine, in the sense that the person did go out? Your evidence or reason is that no sane person would in fact do such things and put them on a clip?
