Each Scene can have any number of compositions. A composition let's you render a scene in a different way, with a different in and out point, different camera moves, and different rendering styles.
A few tips
- To create more contrast between positive and negative space, change the 'Simplify' level.
- To clean the background away from clips, change the Z-threshold
- The rendering styles are screen-blended onto one another. So you can get a lot of mileage out of combining points,wires, and meshes together and varying opacities.
- If your interface is getting crowded you can nudge the timeline widths by pulling on the green stripes at the bottom. Shrink them up and the interface will snap back to the bottom giving your render window some more room.
To create a camera track, move the camera to where you'd like to look at the scene and scrub to the point in time you'd like to view. Press "Set camera point" on the GUI or press SHIFT+T. You'll notice a blue marker appear on the Camera timeline. You can then move the timeline and the camera to a new location and press SHIFT+T again. By selecting "Lock to Track" or pressing SHIFT+L the camera will move along this path and is no longer free floating.
You can click and drag the camera points to change their location in time. You can delete them as well with the Delete or backspace key. By clicking on the beginning or end triangle and hitting the up and down arrows you can have the cameras ease in or out (represented by the curved arc), or cut (represented by the small)
The Depth of Field effect is most convincing for creating a virtual camera language. When Draw DOF is selected in the GUI. By setting the Depth Range you can select which distance is in focus. Tweak the range and blur to achieve the desired effect. Depth of field keyframes matched to camera moves can create really cool convincing rack focus effects. The white rectangle on the top left assists you in focusing. The geometry in focus shows up in black, while everything out of focus is white.
Save the composition when you are ready to export or want to experiment with something else. To switch compositions, click the name of the composition at the top and select a new scene.
Exporting works by rendering the a given composition's camera track into a series of PNG frames that can be compiled into a movie using quicktime or After Effects.
To export, click on the composition name to view all the scenes. Selecting a scene will show all the compositions in that scene, each of which has a small 'R' button next to it. This stands for Render, and by toggling it on you will add this composition to the render queue.
Once you've selected all the compositions you wish to render, click the "Start Render Batch >>" button and sit back and relax as all the compositions you've selected render.
Render frames are 1920x1080 and saved into _RenderBin/ folder underneath the main MediaBin/ (right next to _calibration). Each folder is stamped with the scene, composition, and date so nothing will ever be overwritten.
NOTE: each rendered comp needs a camera track. Weird stuff may happen if you render without one.
