Sometimes you may want to create a view from an additional (fixed or moving) vantage point, to check on and display your track for quality control. You can do that more simply with Shot/Add Render Camera. You can set your resolution, image aspect, shot length, and rate; the defaults will be taken from the current shot.
Then, animate the camera using any available SynthEyes controls: the perspective view, 3-D panel, Graph Editor, etc. Finally, set up your render using the Perspective View Preview Movie controls, and off you go.
Tip: When a perspective view is Locked to a render camera, the Dolly, Look, Orbit, and Pan controls animate the render camera’s path, for easier WYSIWYG setup. This also applies to Field of View changes.
To change the render camera settings after you have created it, select it as the Active Tracker Host, then click Shot/Add Render Camera again. This time, the control dialog will come up as Edit Render Camera instead and its settings will update the existing camera rather than creating a new one.
A Render Camera is a regular camera and shot with a cooked-up file name that stores and generates the empty images and shot settings. (The file doesn’t exist, only the name is significant.) A render camera is not particularly special past that special filename; you can keep spare trackers on the render camera, convert it to a regular camera with Shot/Change Shot Images, or whatever. In the future, we may add user- interface tweaks as seems useful.
Tip: You can change the Empty images color preference to set the color of the images. This affects all empty images, not just render camera images, however.
The file name encoding should be rather transparent (especially if you look at the underlying rendercam.szl script), should you want to generate or alter render cameras from scripts or Synthia. Note that you can’t do it simply from the usual File/Open dialogs, because those look for an existing file.
