Key Frames

OpenShot can use Key Frames to animate a clip.  A key frame is a point in time that contains many settings, such as size, position, and transparency.  There are two ways to set key-frames in OpenShot, manually or with a preset.  

Preset Animation

Many preset animations are available, such as moving a clip from bottom to top of the screen or slowly zooming up on a clip.  To add a preset animation to a clip, right-click on a clip, and choose Animate.

Preset Layout

Many preset layouts are available, such as resizing a clip and positioning it to the corner of the screen or centering a clip.  To add a preset layout to a clip, right-click on a clip, and choose Layout.

Manualmente

To manually create key frames, right click on a clip, and choose Properties.  Switch to the Layout tab, and choose which key frame you want to edit from the dropdown.

Each clip has 2 key frames, the start of a clip, and the end of a clip.  If there are any differences between the start and end key frames, OpenShot will interpolate the difference on a each frame, and thus animate the clip.  The following properties are effected by key-frames:  Height, Wight, X, Y, and Alpha.

For example, consider these key frames:

Start Key Frame:

X=-50, Y=0

End Key Frame:

X =150, Y=0

This would result in the clip animating from the left to the right side of the screen.  The difference in the X setting is interpolated across all frames in this clip.  The longer the clip, the slower the animation.  The shorter the clip, the faster the animation.

If you want to statically change the size or position of a clip, just set the start and end key frames to the same value:

For example, consider these key frames:

Start Key Frame:

X=-50, Y=-50

End Key Frame:

X=-50, Y=-50

This would offset the clip to the top right of the screen.  It would not animate, because the start and end key frames are the same value.

If you need to more than 2 key frames, slice the clip into many pieces, and at the beginning and ending of each slice, you can set the key frames, thus giving you the ability to make an unlimited number of key frames.
