Increasing the setting produces a curved path. A Smoothness setting of 0 produces linear motion from one keyframe to the next. If you want to adjust spatial interpolation-how motion occurs within a video image-change the Smoothness setting in the Event Pan/Crop or Track Motion dialog. To change the interpolation curve, right-click a keyframe and choose a command from the shortcut menu: The interpolation curve determines the rate of temporal interpolation: the rate of motion between two keyframes. When you drag, all keyframes in the time selection will move together.Ĭhange the interpolation curve between keyframes To move multiple keyframes, select the Envelope tool and create a time selection that includes the keyframes you want to move. If track keyframe rows are collapsed, overlapping keyframes will move together. The keyframe will use the same settings and interpolation curve as the previous keyframe.ĭrag the keyframe to a new position in the timeline. ĭouble-click to add a keyframe to the track view. When expanded, a separate row is displayed for each keyframed item.Įvent-level keyframes are not visible in the timeline.Ĭlick the Expand/Collapse Track Keyframes button. When keyframes are locked, you can move events along the timeline, and their associated keyframes move with them.Ĭlick the Expand/Collapse Track Keyframes button in the track header to toggle the height of the track keyframes. Select the Lock Envelopes to Events button to lock track-level keyframes to the events on the track. You can drag keyframes to adjust their position, add and delete keyframes, and change the interpolation curve between keyframes. If you’re using video track effects or track motion, keyframes will be displayed in the timeline below your video track. Repeat steps 3 through 5 to add a keyframe for each effect parameter change.ĭuring playback, the effect will smoothly transition through the attributes you established for each keyframe. In the Keyframe Controller, click to position the cursor where you want to add the next keyframe. Select the Sync Cursor button to synchronize the cursor positions on the main timeline and Keyframe Controller timeline. In the Keyframe Controller, click to position the cursor where you want the effect to start. During playback the event would start playing in color and gradually fade to black and white. The first keyframe would use the Reset to None preset, and the second keyframe would use the 100% Black and White preset. For example, if you wanted to gradually fade an event to black and white, you could use the Black and White effect to create two keyframes. Keyframe animation can be used to smoothly and gradually modify an effect.
