Every clip in Premiere Elements is composed from three color channels: red, green, and blue. Each channel contains the luminance values for its respective color. Using the Channel Mixer effect, you can add the values from any of these channels to any of the other channels, for example, adding the luminance values from the green channel into the red channel. Use this effect to make creative color adjustments not easily achieved with the other color adjustment tools. Create high‑quality grayscale clips by choosing the percentage of the grayscale contributed by each color channel, create high‑quality sepia‑tone or other tinted clips, and swap or duplicate channels. You could use this effect, for example, to entirely replace a noisy blue channel with values taken from, say, a clean green channel.
Each of the properties for the Channel Mixer is labeled with a pair of color names. The word to the left of each hyphen names the property’s output channel; the word to the right names its input channel. For example, the Red-Green property has the red channel as its output and the green channel as its input. You can use it to add the luminance values of the green channel to the red channel.
As a video or film producer, you must have the same level of control over the sound of your piece as you do over the images. Premiere is the video editing component of Adobe's Creative Suite, and gives you the audio editing capabilities you would expect from software that has been used to produce feature films. Fading audio in and out in Premiere is quick and convenient, and detailed tweaking is also possible if needed.
1. Locate the audio clip in the timeline that you want to fade. Focus the timeline view on the left or right end of the clip for a fade in or a fade out, respectively.
2. Expand the Audio Transitions folder in the Effects panel, then expand the Crossfade folder.
3. Choose a fade type: Constant Gain, Constant Power, or Exponential Fade. The Constant Gain fade changes the volume at a constant rate (linearly). The Constant Power fade adds an acceleration or deceleration to the volume, which can make the fade sound less abrupt. The Exponential Fade is similar to the Constant Power fade, but uses logarithmic functions and is more gradual.
4. Click and drag the fade type you chose into the timeline, positioning it so that it snaps to the edge of the clip. Press the "S" key during your drag to toggle snapping if necessary.
5. Double-click the audio fade you just added in the timeline to change its speed. Type a duration for the fade into the pop-up window that appears and click "OK."
- To crossfade 2 adjacent audio clips, drag a fade onto the end of one of them as described above, then click to select it and choose Center at Cut from the Alignment drop-down menu in the Effect Controls panel.
- Change the default audio fade length in the General section of the Preferences.
