Unlike panoramas, which are represented by a single panoramic Pict file, QTVR objects are represented by a sequence of individual, discrete views. Each view is rendered or captured as a single Pict or video frame, but adjoining images are not "stitched" together as happens with QTVR panoramas. Instead, it is the ordered sequence of views which enables QTVR to provide the apparent smooth transitions between the various views.

Types of QTVR Object Movies
The basic QTVR object movie generally consists of a number of individual views and can be created with three different kinds of cursors:
- standard drag cursor with edge rotation cursors
- drag-only cursors (no edge rotation cursors)
- joystick cursor (object rotates when mouse is down, dragging increases speed of rotation)
QTVR objects can also contain animated views, which play back as continuous loops or as a single animation sequence. Objects can also be scalable, allowing the user to zoom into the object for a closer view.
There is a final type of object movie called an absolute referenced object. With these movies, it is as if the viewing frame is overlaid with an invisible grid. When the mouse is clicked within the viewing window of the object movie, the position of the cursor within the grid prompts the display of an image associated with that position.
