Adding key frames to video effects
You can create key frames, which define the settings for a video effect at different points in time within your production, image, or video clip. During the time between the key frames, the effect settings are gradually changed from the settings defined in the first key frame to the settings defined in the second key frame.
For example, if you apply the SearchLights2D effect to your production, you can set the brightness and speed to a high level at the beginning of the production, and set them to a lower level five seconds into the production. To do so, you use key frames at the beginning of the production and at the five-second position.
By default, when you add a video effect, start and end key frames are added for you. You can add additional key frames.
To add a key frame:
1 Select the video effect for which you want to define key frames, and display the effect Settings panel.
2 Click the Keyframeable Settings button.
3 In the Preview window, use the jog wheel or slider to move the playback head to the position at which you want to add the key frame.
4 Click Add key frame here to add a key frame.
5 Make sure that the key frame is selected in the Key frame drop-down list, and adjust the effect settings for the key frame.
6 Optional: To show the key frame position as an offset from the end of the effect area, instead of from the beginning, click Offset from end.
7 Optional: To adjust the time position of the key frame, use the jog wheel on the Settings dialog box.
8 Repeat step 3 to step 7 for each key frame you want to add.
Tip: You can also delete a key frame, by selecting it in the Key frame list and clicking Delete.
