<h1>Animations</h1>
<p>Animated images (GIF, APNG, WEBP), are very popular.
An animation has several static images - <b>frames</b>, and the information, for how long each frame should be displayed (before going to the next frame).
Photopea can open, edit and save animations.</p>
<h2>Animations in Photopea</h2>
<p>Photopea can make an animation from layers of the document by showing a different layer in each frame.
To define a new frame, the layer name should start with <code>_a_</code>. It can be a regular layer, a folder of layers, or any other layer.</p>
<p>When you export such document as a GIF, PNG or WEBP, Photopea detects all layers starting with <code>_a_</code>.
The first such layer is shown in the first frame (others starting with <code>_a_</code> are hidden).
The second such layer is shown in the second frame, etc.</p>
<p><b>Example</b>: we have five layers: <code>background, _a_dog, _a_cat, _a_tree, watermark</code>.
The GIF will have three frames (3 layers start with <code>_a_</code>).
<code>background</code> and <code>watermark</code> will be in all frames.

<img src="//i.imgur.com/UNSrMiz.gif" style="width:60%;">
<p>When you open an animation (GIF, APNG, WEBP) in Photopea, Photopea will turn every frame into <b>a layer with a proper name</b>.
So when you edit an animation (delete frames, reorder frames, resize ...), there is no need to change layer names.</p>
<h2>Delay</h2>
<p>A layer which starts with <code>_a_</code> makes a new frame, which will be shown for 50 ms by default.
To set your own delay, put <code>,</code> and a number to the end of the layer name. E.g. <code>_a_dog,500</code> will be displayed for half a second.</p>
<h2>Merge frames</h2>
<p>Let's say we have 3 frames of one animation and 3 frames of another, i.e. six layer starting with <code>_a_</code>.
The resulting GIF will have six frames. Can we make these two animations play simultaneously "in parallel"?</p>
<p>We need to turn it into 3 frame layers, where each layer contains images from both animations.
We can do it manually: merge each two layers into one using Layer - Merge Layers.</p>
<img src="//i.imgur.com/DhHxnzF.png" style="width:60%" />
<p>We can do it automatically. Put each animation in a folder and press <b>Layer - Animation - Merge</b>.</p>
<img src="//i.imgur.com/lTZnWQv.png" style="width:60%" />
<p>Photopea will find all folders, and merge their frames together.
Alternatively, you can select only folders you want to merge (in Layers Panel) before pressing Layer - Animation - Merge.</p>
