Setting the properties of movies
When you create a movie, you should begin by setting the stage size and frame rate and choosing a background.
In Corel R.A.VE. the length of a movie is determined by the life span of objects within the movie. You cannot set the length of a Corel R.A.VE. movie in advance, because it changes as you extend the life of objects within it. For more information about setting the life span of objects, see "Setting the life span of objects" in the Help.
Setting the stage size and frame rate of a movie
A movie consists of a succession of frames that are displayed on the stage (500 x 500 pixels by default). You can customize the stage size of a movie by specifying its width and height.
The frame rate of a movie refers to the number of frames that are played per second. The frame rate affects the smoothness of the animation and the file size of a movie. Usually, higher frame rates result in smoother animation and larger files, while lower frame rates result in choppier animation and smaller files. The default frame rate in Corel R.A.VE. is 12 frames per second, the optimal rate for the Web. The typical frame rate of motion pictures is 24 frames per second.
Choosing a background
By default, all movies have a solid white background. You can choose another color, or you can use a bitmap such as a textured design or photograph to create a more intricate or dynamic background. You can also remove a background.
When you choose a bitmap as the background, it is embedded in the movie by default. This is the recommended option. However, you can also link the bitmap to the movie so that if you later edit the source image, the change is automatically reflected in the movie. If you send a movie with a linked image to someone else, you must also send the linked image.
If the bitmap is larger than the stage, it is cropped. If the bitmap is smaller than the stage, it is tiled across the stage. You can change the size of the background bitmap to create smaller or larger tiles.
- You can enhance a movie by adding a background. Clockwise from top-left: solid color background, bitmap background, tiled bitmap background, cropped bitmap background.
