Animation¶
OpenShot has been designed specifically with animation in mind. The powerful curve-based animation framework can handle most jobs with ease, and is flexible enough to create just about any animation. Key frames specify values at certain points on a clip, and OpenShot does the hard work of interpolating the in-between values.
Overview¶
| # | Name | Description |
|---|---|---|
| 1 | Green Property | When the play-head is on a key frame, the property appears green |
| 1 | Blue Property | When the play-head is on an interpolated value, the property appears blue |
| 2 | Value Slider | Click and drag your mouse to adjust the value (this automatically creates a key frame if needed) |
| 3 | Play-head | Position the play-head over a clip where you need a key frame |
| 4 | Key frame Markers | Small green tick marks are drawn at all key frame positions (on a clip) |
Key Frames¶
To create a key frame in OpenShot, simply position the play-head (i.e. playback position) at any point over a clip, and edit properties in the property dialog. If the property supports key frames, it will turn green, and a small green tick mark will appear on your clip at that position. Move your play-head to another point over that clip, and adjust the properties again. All animations require at least 2 key frames, but can support an unlimited number of them.
To adjust the interpolation mode, right click on the small graph icon next to a property value.
| Name | Description |
|---|---|
| Bézier | Interpolated values use a quadratic curve, and ease-in and ease-out |
| Linear | Interpolated values are calculated linear (each step value is equal) |
| Constant | Interpolated values stay the same until the next key frame, and jump to the new value |
For more info on clip properties, see Properties. For more info on preset animations, see Preset Menu. For more info on creating key frames for location and scale, see Transform.
Bézier Presets¶
When using a Bézier curve for animation, OpenShot includes more than 20 curve presets (which affect the shape of the curve). For example, Ease-In has a more gradual slope at the beginning, making an animation move slower at the beginning, and faster at the end. Ease-In/Out (Back) has a gradual beginning and ending, but actually goes past the expected value and then back (producing a bounce effect).
To choose a curve preset, right click on the small graph icon next to a key frame.
Image Sequences¶
If you have a sequence of similarly named images (such as, cat001.png, cat002.png, cat003.png, etc…), you can simply drag and drop one of them into OpenShot, and you will be prompted to import the entire sequence.
To adjust the frame rate of the animation, right click and choose File Properties in the Project Files panel, and adjust the frame rate. Once you have set the correct frame rate, drag the animation onto the timeline.
| # | Name | Description |
|---|---|---|
| 1 | File Properties | Select an image sequence in the Project Files panel, right click and choose File Properties |
| 2 | Frame Rate | Adjust the frame rate of the animation. Typically, hand-drawn animations use 12 frames per second. |
