In addition to sequencing your clips, editing
will also sometimes involve adding fades and other transitions to your project. I’m Axel
Wilkinson, for HitFilm.com, and in this video we will learn how to work with Transitions,
and how to adjust the Opacity of your video and the levels of your audio. Before we get
started, you can download my project file, if you want to imitate my every move.
In the Effects Panel, we have folders of video transitions and audio transitions, both of
which can only be used on the Editor timeline. To use a transition, find the one you want,
and then drag it onto the timeline and drop it on the end of a clip, where you want it.
For example, if we find a Cross Dissolve, and drag it to the end of our last clip, the
clip will fade out, dissolving to black. However, in most cases, transitions will be used to
span two clips, to transition from one shot to the next. Drag our transition to the first
edit point on our timeline, and you can place it centered on the edit, or butt it up against
either side. After you drop it in place, you can easily adjust the duration by dragging
the ends. Open the Wipes folder, and add a Linear wipe
to one of the edits. Now open it in the Controls panel, and we can adjust the angle of the
wipe, and the edge feather. Some transitions will have properties to be adjusted, while
others will not. Its worth mentioning that a real edit is not
likely to use this many transitions this close together. In reality, this sequence probably
wouldn’t use any transitions, but that would make for a boring tutorial about transitions.
So, for the purposes of demonstration, I’ve gone a bit overboard.
We can also adjust the Opacity of video, and the Levels of audio, on the Editor timeline.
Just below the title bar of each clip, there is a line that we can drag up and down. On
video, this is the opacity bar. On audio, this is the Levels bar. In either case, if
we position our cursor over the line, it will become a double arrow, allowing us to drag
the bar and make adjustments. Drag the Level bar of the Shotgun sound upward all the way,
to make it louder. Sometimes, you may need to adjust these controls over time. Keyframes
allow us to do so. Near the end of the first clip, hover over
the Opacity bar and CTRL+Click on Windows or CMND+Click on Mac to create a keyframe
on the video opacity bar. Now create another keyframe, a little bit farther along. As we
position the mouse over either one of these, two crossed lines appear, letting us drag
the keyframe left or right to set its timing, and up or down to adjust the opacity. Drag
the left keyframe all the way left, and all the way down. Then drag the other one all
the way right, and up. Now the clip will gradually fade in, increasing in opacity over its entire
duration. If you need to place a keyframe right at the end of a clip, its easiest to
create it closer to the middle, then drag it to the end.
You can create as many keyframes on a clip as you need to. So if you need to dip the
audio quickly, to remove an unwanted sound, for example, then you can easily do so. Let’s
use this technique to remove the popping sound of the prop gun as it fires. Turn off audio
track 2 by clicking the Speaker icon. These eyes and speakers toggle each track of the
editor on and off. Now play through that bit of the timeline, and you can hear the sound
of the prop. Add three keyframes to the audio for that shot, near the middle. Drag the first
one to just before the Shotgun sound, and match the level with the clip that comes before.
Drag the middle one all the way down, and line it up with the start of the Shotgun.
Position the third one about halfway between the second keyframe and the end of the clip.
In the Controls panel, open the Properties for the clip, then move the playhead to the
position of our keyframe, and set the Level to -20 db. Both the Opacity of video and the
Level of audio are also available here in the Controls panel, so you can set exact values
for any keyframe. Drag the audio bar for the last clip down,
so it roughly matches our last keyframe. If you want to be exact, you can manually set
the Level of the last clip in the controls panel. Play through to see if the pop is properly
removed. If you still hear it, adjust the keyframes as needed. Then, turn Audio 2 back
on, and play through the timeline. Opacity and Levels are the only properties
that can be animated over time on the Editor. If you need to use keyframes with any other
properties, you can convert the clip to a composite shot to access full keyframing capabilities.
We will look more at working with composite shots in our next tutorial. Until then, I’m
