Stereoscopic Movies
3-D movies have had a long and intermittent history, but recently they have made a comeback as the technology improves, with polarized or frame-sequential projectors, and better understanding and control over convergence to reduce eyestrain. 3-D movies may be a major selling point to bring larger and more lucrative audiences back to theaters.
Filmmakers would like to use the entire arsenal of digital techniques to help produce more compelling and contemporary films. SynthEyes can and has been used to handle stereo shots using a variety of techniques based on its single-camera workflow, but there are now extensive specialized features to support stereo filmmaking.
SynthEyes is designed to help you make stereo movies (Pro version, not Intro). The stereo capabilities range from tracking and cross-camera linking to solving, plus a variety of user-interface tweaks to simplify handling stereo shots. A special Stereo Geometry panel allows constraints to be applied between the cameras to achieve specific relative positions and produce smoother results. Additional stereo capabilities will be added as the stereo market develops.
STOP ! Stereo filmmaking requires a wide variety of techniques from throughout SynthEyes: the image preprocessor, tracking, solving, coordinate system setup, etc. The material here builds upon that earlier material; it is not repeated here because it would be exactly that, a repetition. If this is the first part of the manual you are reading, expect to need to read the rest of it.
You will need to know a fair amount about 3-D movie-making to be able to produce watchable 3-D movies. 3-D is a bleeding edge field and you should allow lots of time for experimentation. SynthEyes technical support is necessarily limited to SynthEyes; please consult other training resources for general stereoscopic movie theory and workflow issues in other applications.
SynthEyes's perspective view can display anaglyph (red/cyan is a good combination) or interlaced views from both cameras simultaneously, controlled by the right-click menu's View/Stereo Display item and the Scene Settings panel. You can select either normal color-preserving or gray-scale versions of the anaglyph display. When using an interlaced display, you should probably have more than one display and float the interlaced perspective to that monitor. Only the actual perspective view will be interlaced, not the entire user interface.
