The RotoPaint properties panel includes a set of controls that you mainly need when you're editing the attributes of a shape. You can find these on the Shape tab in the properties panel.
To soften the edges of a shape, do the following:
1. | With your shape selected, check the on box next to the feather slider on the Shape tab to apply feather to your shape. If you don’t want any feather on your shape, uncheck the on box. |
2. | Use the feather slider to add outward or inward feather around the whole shape. With positive feather values, your feather effect is outward and, respectively, if your feather values are negative, the feather effect is inward. |
3. | Use the feather falloff slider to adjust the falloff profile. Falloff is measured in pixels. You can also change the type of the falloff using the falloff type dropdown menu. Select either linear, smooth0, smooth1 and smooth. Each of these produces a different rate of falloff that may be helpful for example in matching the soft edge to motion blurred image content. |
4. | To add feather to a single point, right-click on the point in the Viewer and select increase feather. The shortcut for this is E. If you press it several times, every press adds more feather. |
5. | Use the feather handle on the point to add feather into the point. By default, the point angle is locked, and moving the point unlocks the angle. |
You can also select several feather points and move them together.
6. | To remove feather from a point, right-click on the point and select reset feather or use the shortcut Shift+E. |
7. | If you disable feather link mode (enabled by default) in the RotoPaint tool settings, the feather and shape points move independently. |
• centered - to center the shutter around the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29.5 to 30.5.
• start - to open the shutter at the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 30 to 31.
• end - to close the shutter at the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29 to 30.
• custom - to open the shutter at the time you specify. In the field next to the dropdown menu, enter a value (in frames) you want to add to the current frame. To open the shutter before the current frame, enter a negative value. For example, a value of - 0.5 would open the shutter half a frame before the current frame.
