Before you buy a clip for a headset, it pays to know what the file actually is. Producers describe formats in different words, and a few of those words mean something very specific. This page translates the common labels so you can judge a listing in seconds.
VR180 and stereoscopic side-by-side
The most common real VR format in fetish clips is VR180: a half sphere in front of you, recorded with two lenses. The file stores both views next to each other, which is why the raw preview looks like two almost identical pictures side by side. In a headset player you set the format to 180° and side-by-side, and the image wraps around your field of view with depth. Words to look for: VR180, 180°, SBS, stereoscopic, 3D.
360 degrees
A 360 clip surrounds you completely. That sounds better than it usually is for close scenes: the resolution is spread over the whole sphere, so the part in front of you – where everything happens – gets fewer pixels than in a VR180 clip of the same file size. Many 360 clips are also mono, meaning one image without depth. If a listing says 360 but not stereo or 3D, expect a panorama, not presence.
Flat POV
A flat POV clip is ordinary video filmed from the viewer’s position. You can still watch it in a headset on a virtual screen, but it will not have depth. That is not a flaw – a well-made POV clip can be more convincing than a careless VR one – but it should not be sold as VR. On this site, flat POV clips appear below the real VR grid and are never labelled as VR.
Resolution and length
For VR, the number on the label means less than it seems. 8K across a side-by-side file is roughly 4K per eye, and only a part of that is in front of you. A clip labelled 5K or 6K VR180 can look sharp; anything below that will look soft in a modern headset. Length matters too: a twenty-minute VR clip is a large download, so check the file size before buying on a slow connection.
Quick checklist
Two images side by side in the preview, a format label such as VR180 or SBS, and a resolution of 5K or more: that is a real headset clip. One image and a POV tag: a flat first-person clip. Neither: an ordinary scene. For what makes the difference once you are wearing the headset, read sound, distance and presence.
