![]() ![]() ![]() Select the Pen tool to set your keyframes on the audio overlay line, then move the keyframes points up or down to effect change. The Process for keyframing audio in the Timeline is exactly the same as keyframing opacity. This process is often referred to as 'rubber banding'. If you want to fade out the clip at the end simply add two more keyframes with the last one pulled back down to zero. It will continue to play at 100% until it encounters another keyframe that would change the opacity once again. As the clip is played from the first frame, the opacity of the clip ramps up from 0% opacity to 100% opacity at the point of the second Keyframe. Then further on we have set a second Keyframe with the opacity set to 100%. What we have done here is placed a Keyframe on the very first frame of the clip and set the opacity to 0%. Pull the Keyframe all the way down so that the opacity is at 0.Place the Pen tool on top of the first Keyframe, it will turn into a + sign.Move the Pen further down the overlay line and set a second Keyframe.Click to set a Keyframe which will show up as a black dot.Place the Pen tool on the overlay line at the first frame of the clip.Opacity overlay line at the top of the clip.To Keyframe the opacity of a clip first select the 'pen' tool from the tool palette or hit 'p' on the keyboard. What we are looking for is a way to vary the opacity or volume up or down as the clip plays. This is fine for overall adjustments like matching the volume of one clip to the next but this change is constant for the entire clip. To reset opacity or audio simply drag back up to 0.Īs you can see, pulling down the overlay line pulls down the line for the entire clip. In the picture on the right I have lowered the volume of the audio by 6 dBs. In the center picture below, I have lowered the opacity to 45%. As you drag the overlay line downward, a yellow box will pop up showing the amount of change. ![]() If you place your cursor on a level overlay line it will turn into a 'up and down' arrow. ![]() These 'clip overlays' are what we will work on to achieve the desired results.īefore we start to set Keyframes let's look at these level overlay lines. In the video track, a black line and in the audio tracks, pink lines. You will now have horizontal lines running the length of your clip. Turn on 'clip overlays' (pink arrow at right). At the end of the clip I want both to fade out.įrom the lower left hand side of the TL, enlarge the TL so that you have some room to work (blue arrow right). I have a clip in the Timeline, I want to fade in both the audio and the picture. In Final Cut Express we can do our keyframing work in two places in the interface, the Timeline and the Canvas window. This is the heart of video animation and special effects. Final Cut Express will interpolate or generate all the frames needed between the Keyframes so that the change will happen smoothly, over time. Further down the Timeline, where we want the change to be completed we mark that frame with a second keyframe. When we set a keyframe in Final Cut Express, we pick an exact frame that we want our change to begin and mark that video frame with a keyframe. We can change the size of our clips, move them around the screen as in 'Picture in Picture', rotate, crop or distort them. We can fade a clip in and out, fade the audio up or down as well as lower or raise the volume of the clip in different places. In Final Cut Express we have the ability to change elements of our video as it plays on the screen. Keyframing gives us the ability to change the appearance of our video over time and to make things move. All of these effects are created using Keyframes. At the end of the movie the credits scroll up the screen. In a crazy dream sequence images dance their way across the screen, spinning and changing size and position as they go. A television news broadcast tells a story and at a certain point a small picture depicting elements of the news story appears on screen in a small window, then disappears. Then, slowly, both the picture and background music begin to fade in. 1.0.1Īs the movie starts, the screen is black and all is quiet.
