<p>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.</p>

<h2>Key Frames<a class="headerlink" href="#key-frames" title="Permalink to this headline">¶</a></h2>
<p>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.</p>
<p>To adjust the <strong>interpolation mode</strong>, right click on the small graph icon next to a property value.</p>

<h2>Bézier Presets<a class="headerlink" href="#bezier-presets" title="Permalink to this headline">¶</a></h2>
<p>When using a Bézier curve for animation, OpenShot includes more than 20 curve presets (which affect the shape
of the curve). For example, <strong>Ease-In</strong> has a more gradual slope at the beginning, making an animation move slower at
the beginning, and faster at the end. <strong>Ease-In/Out (Back)</strong> has a gradual beginning and ending, but actually goes past
the expected value and then back (producing a bounce effect).</p>
<p>To choose a curve preset, right click on the small graph icon next to a key frame.</p>

<div class="section" id="image-sequences">
<h2>Image Sequences<a class="headerlink" href="#image-sequences" title="Permalink to this headline">¶</a></h2>
<p>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.</p>
<p>To adjust the frame rate of the animation, right click and choose <strong>File Properties</strong> in the <strong>Project Files</strong> panel,
and adjust the frame rate. Once you have set the correct frame rate, drag the animation onto the timeline.</p>
