Animation Controls Besides creating an animation, there are a number of controls for the animation system that you need to set, such as the length, and the type of time code and video system to use. This tutorial shows you the animation controls that are available in Realsoft 3D. Animation length You can change the total length of your animation at any time using the 'Total' field in the animation window. Animation consisting of 150 frames. To add new frames to your animation (increase the length), enter the desired value in the 'Total' field and press the Enter key. A dialog appears asking if you want to scale the timelines for any animated objects. To add new frames without affecting the length of any currently defined animations, select No (do not scale the time lines). If you want to scale the existing animation timelines to include the new frames being added, select Yes. You remove frames (shorten) from an animation by the same process as adding frames: type a new length into the 'Total' field and press Enter. However, be aware that if you decrease the total number of frames to less than the length of any particular choreograph, and do not scale the timelines, such choreographs will be affected. Again, you always have the option of using the 'Time Lines' tab of the choreography editor to make adjustments. Note: You may find it easier to not to use the scaling feature when you add or remove frames from the total animation length. This is because in certain cases (changing the length several times) it is easy to get results that you may not have intended. You can easily adjust the timeline of any choreograph using the 'Time Lines' tab of the choreography editor. Setting the time code and video system Before you start an animation project, you should set the type of time system and video system to use. To access the Time code settings, open the Options window from the main menu ('Options/Window'), and click the 'Animation' tab. Specify time units to be used For the Time System, you have three options: Frames (default). Time values are in units of frames. The number of frames needed to comprise one second depends on the video system setting. Real Time. Time values are in units of minutes, seconds, and frames. This is the standard time code system used by video equipment, and is also dependent on the video system setting. Seconds. Time values are shown in units of seconds. This system may be more natural if you are doing physical simulations, or are using physical formulas within an animation. You can change the time system being used for a project at any time. The user interface automatically adapts to the selected time system. For example, if you select the time code value, three fields (minutes, seconds, frames) are used to show animation timing. Also, changing time system does not affect any existing motion definitions. The time system only affects how the user interface displays time attributes. The time line showing real time units The video system can be defined through the Animation Settings window.You can find this window below the select window in the default startup project. Suspending and resuming animation rendering Realsoft 3D allows you to start and stop the rendering of a project or scene at any time, without losing the work that has been performed. This is quite useful when rendering long animation sequences. Assume that you have started rendering a long animation, say 1200 frames, and you want to stop the rendering for some reason, and then resume it again later from the point at which it was stopped. The controls for doing this can be accessed either from the file rendering window, or from the main menu. To stop rendering an animation, press the 'Stop' button on the file rendering window, or make the following selection from the main menu: 'Animation/Playback/Stop'. Then use 'File/Save As' to save the entire project. The current time is saved with the project. You can then load the project again at any time, and click the 'Play' button on the file rendering window, or select 'Animation/Playback/Play' from the main menu to continue rendering the project. Defining project-specific animation settings Every time you create a new animation, you have to define a number of project-specific animation options. For example, you have to decide whether to use motion blur. You might also want to use field rendering. These options can be defined through the Animation Settings window. You can find this window below the select window in the default startup project. Project-specific animation settings If you select the 'Motion Blur' option, you also need to specify the desired sample count in the 'Samples' field. The higher the value, the better the quality of the generated motion blur (Note that higher values will affect your rendering time). If field rendering or motion blur is activated, the animation playback window will show controls that allow you to control and select time in units of fields and motion blur samples, as well as frames. This allows you, for example, to access the time line at finer resolutions, such as Frame=2, Field=odd, and Sample=3, and then, for instance, modify an object to create a key frame. You can also define 'start frame' and 'end frame' attributes which allow you to play desired sub range of the animation.Check 'Play range' and enter desired start frame and end frame values to activate sub range feature. This also adds range knots to the time slider. You can drag the knots to specify a desired frame range. 'Play Range' option activated, start and end frame knots shown.
