Comment créer un arrière-plan animé dans Photoshop

How to create an animated background in Photoshop

If you've been on social media recently, you might have noticed some moving images on your news feed. The same can be said for some business websites and personal blogs. 

In this scenario, what you are really seeing is an animated GIF file that allows movement in the static images. It's a bit like a hybrid between a video and a still image. 

A GIF can be a handy tool to get people interested in an image. If you get very creative, moving images can grab the viewer's attention very quickly. So it is worth the time and effort to experiment with moving images to improve the images on your website and on social media platforms.

The good news is that GIFs really aren't that hard to make. If you have access to Photoshop and a few minutes to spare, you can quickly create an animated GIF that will grab attention.

For this tutorial, we're going to create an eye-catching background image.

Step 1: Customize the image size

Let's start by customizing the image size to 1920px × 1080px.

Step 2: Upload images or create them one at a time as layers

If you already have a few images in mind, save them in a single folder and upload them to Photoshop. 
You can do this by clicking on: File> Scripts> Upload Files to Stack

Then you can browse and select the images you like and click OK. When you do this, Photoshop automatically creates individual layers for each image. 

You can follow along if you already have the images ready, but to give you a better idea, we'll select an image and then create each image by setting up individual layers. 

The image used for this tutorial can be downloaded

If you want, you can also adjust the image with effects like Brightness and Contrast etc.

Step 3: Place the text in new layers

To add a new layer, just click on Layer> New> Layer.

Make sure to name each layer so that it's easier to follow them as you work on creating your GIF. 

To name each layer, go to the Layer panel at the bottom right and double click on the default layer name (Layer 1) and type the name you want and press Enter. 

For this tutorial, we're going to put in around 12 layers to highlight the DJ name K-Beast. The first layer will have the entire name in light gray, and the next 11 layers will represent each letter in white.

Tip: To get there quickly, right click on the layer and click Duplicate Layer and repeat this process until every letter is white. Besides, it will also be easier if you turn off the icon that looks like an eye to hide each layer as you perform the movements.

Step 4: Set up a timeline

Once you've set up each text layer, you're ready to open a Timeline, so click Window> Timeline. 

The Timeline tool allows you to turn different layers on and off at different times. This, in turn, will turn your static image into an animated GIF.

Step 5: Create Frame Animation

Go to the Timeline window and select Create Animation from the drop-down menu in the middle of the window.

Your Timeline should now look like this.

Then go to Select> All Layers 

Once you've done that, click the drop-down menu on the right side of the Timeline window and click on Create New Layer For Each New Image.

Once you've done that, go back to the same drop-down menu and select Make Frames from Layers.

Step 6: Select the time for each image

Then, under each image, select how long you want each image to appear before moving on to the next image. For this tutorial, we're going with 0.1 seconds to make it quick. 

Besides, you can also choose how many times you want to loop. If you want to repeat it, select Always.

Time for frames

Maintenant, vous remarquerez qu'il y a plus de cadres que prévu, mais c'est parce que l'espace entre les deux mots, l'image d'arrière-plan, et les effets (si vous en avez utilisé) auront besoin de leurs propres cadres.

Une fois que vous avez terminé, cliquez sur le bouton de lecture pour prévisualiser le GIF. Si vous êtes satisfait, vous pouvez passer à l'étape suivante et enregistrer le fichier. Mais si vous ne l'êtes pas, vous pouvez toujours revenir en arrière et apporter des modifications à un ou plusieurs calques / cadres.

Étape 7: Exporter le fichier en tant que fichier GIF

Once you're ready to save the file, go ahead and choose File> Export> Save For Web (Old Version). 

Then choose the type of GIF you want to save from the drop-down menu. If you have gradients, go for rasterized GIFs to cancel out the color banding, but if you have a lot of colors, choose no dithering.

Now you are ready to have fun with your new GIF!
