StreamLive Pro

Keyframes and effects in the video editor

Animate a clip with keyframes in the StreamLive Pro editor, such as a slow zoom, a move or a fade of opacity, and add looks like black and white or a vignette.

Keyframes make a clip change over time: a slow zoom in, a picture that slides across, a logo that fades. In the StreamLive Pro editor, right-click a clip and choose Keyframes. Add a keyframe at one moment, move the playhead, add another with a different value, and the editor moves smoothly between them. Effects are different: they give the whole video a look, such as Black & White or a vignette, from the Effects tab.

Before you start

• What can be animated. On video and image clips: Opacity, Scale, Position X, Position Y and Rotation. On audio clips: Volume.
• Keyframes reach the file. Opacity, scale, position, rotation and volume animations are rendered into the exported MP4.
• Effects apply to the whole video, not to one clip. Several effects can be stacked.
• Open the project. In the menu choose Video editor.

Steps

The example is a slow zoom in on a speaker.

1. Right-click the clip. On the timeline, right-click the clip you want to animate and choose Keyframes. A small panel opens with one row per property.
2. Put the playhead at the start. Move it to where the zoom should begin.
3. Add the first keyframe. In the Scale row press + Add at playhead. It takes the current value, 1 (normal size).
4. Move the playhead. Go to where the zoom should end, for example five seconds later.
5. Add the second keyframe. Press + Add at playhead again and change its value to 1.2. The clip will grow by 20% between the two points.
6. Choose the motion. Each keyframe has an easing: Linear, Ease In, Ease Out or Ease In-Out. Ease In-Out starts and ends gently, which suits a slow zoom.
7. Watch it. Play the part. Too fast? Move the second keyframe later by editing its time.
8. Export. Press Export.

How keyframes behave

• Before the first keyframe the clip keeps the first value; after the last one it keeps the last value.
• One keyframe alone holds that value for the whole clip.
• Each keyframe shows its time (in milliseconds) and its value; both can be typed. The Delete button next to it removes it.
• Opacity and volume run from 0 to 1. Scale 1 is the original size; values above 1 enlarge.
• Dragging a slider does not record a hundred undo steps; the change is recorded once.

Common animations

Effects

Open the Effects tab in Properties and click an effect to apply it. Each active effect has an Intensity slider and a Remove button; Reset all clears them.

Only effects that reach the exported file are listed. Effects that would show in the preview and vanish in the file are kept out of the list. For colour fixes rather than a look, use Color correction.

What can go wrong

• The animation jumps instead of moving. The two keyframes are too close in time. Spread them further apart.
• The zoom shows the edge of the frame. Scale below 1 shrinks the clip and shows what is under it. Keep scale at 1 or above for a zoom.
• Nothing moves. There is only one keyframe, which holds one value. Add a second with a different value.
• The whole video changed, not one clip. Effects are project-wide. To animate a single clip, use keyframes.

Frequently asked questions

How do I make a slow zoom on a video?

Right-click the clip, choose Keyframes, add a Scale keyframe at 1 where the zoom starts and another at about 1.2 where it ends. Choose Ease In-Out for a gentle move.

Are keyframe animations included in the export?

Yes. Opacity, scale, position, rotation and volume keyframes are rendered into the MP4.

Can I apply an effect to one clip only?

No. Effects apply to the whole video. To change one clip over time, use keyframes on that clip.

Can I combine several effects?

Yes. Click more than one effect; each has its own Intensity slider.
