You can also use the Composition Browser to manually set keyframes. The following procedure uses the same example of adjusting the amount of gray in an image.

To animate the amount of gray in an image using the Gray tool in the Composition Browser:

1. Expand the Gray tool in the Composition Browser.
2. Mark the Amount attribute for keyframing by selecting its radio button in the M column.

   

3. At the first frame, leave the initial value as is.
4. Select the Set Keyframe button to set a keyframe on the Amount attribute.

   A green line appears over the attribute’s value, indicating a keyframe has been added for this attribute at that frame.

   

5. Move the time cursor in the Player navigation bar to frame 30.
   NoteWhen you move the time cursor to the next frame, you will notice that the green line turns red, indicating that the attribute is animated, but has no keyframe at the current frame.
6. Click in the value editor in the Composition Browser and either type the new amount of gray, then press Enter, or drag inside the value editor.

   

7. Repeat steps 4 to 6 as required.
8. Select Frame or Frame All to see the curves in the Animation Editor.
