How to Install Custom Boot Animation on Steam Deck in 2026

Updated June 30, 2026
By

The Steam Deck’s default Valve boot animation takes about four seconds and cannot be changed through official settings. Replacing it with a custom video — a game intro, a retro boot screen, anything in the right format — is a straightforward process using Decky Loader, an open-source plugin framework that sits outside the official Steam OS update path and survives system updates without reinstallation. This guide covers the full 2026 process, including the format requirements that trip most people up on their first attempt.

What Is a Custom Boot Animation on Steam Deck?

The Steam Deck displays a short video animation when it powers on — the default is Valve’s white logo animation. A custom boot animation replaces this with any video clip you choose. Common choices include game intro sequences, anime openings, retro boot screens, and custom artwork animations. The change is purely cosmetic and has no effect on performance or stability.

Does Installing a Custom Boot Animation Void My Warranty?

No. Valve has explicitly stated that using Desktop Mode and installing software on Steam Deck does not void the warranty. The Decky Loader plugin framework used in this guide is widely used by the Steam Deck community and is considered safe. You can always restore default settings by removing the custom animation.

What You Need Before Starting

  • Steam Deck (any model — LCD or OLED)
  • A USB-C dock or hub (recommended for keyboard/mouse access in Desktop Mode)
  • A video file for your boot animation (MP4, WebM, or the correct format — see below)
  • Decky Loader installed (free, open source)
  • The BootVideos or Animation Changer plugin from the Decky Store

Boot Animation Requirements in 2026

Your custom boot animation video must meet these specifications for it to work correctly:

  • Resolution: 1280×800 (native Steam Deck resolution)
  • Format: WebM (VP9 codec) or MP4 (H.264)
  • Duration: 3-8 seconds recommended (can be longer but shorter is smoother)
  • Frame rate: 30fps or 60fps
  • Audio: Boot animations are muted by default — audio won’t play
  • File size: Keep under 50MB for fast loading

How to Install a Custom Boot Animation on Steam Deck (2026)

Step 1: Install Decky Loader

Decky Loader is the plugin framework that makes boot animation installation easy. If you already have it installed, skip to Step 2.

  1. Press the Steam button on your Steam Deck and go to Power → Switch to Desktop
  2. Open Firefox (the web browser) in Desktop Mode
  3. Go to decky.xyz and download the installer
  4. Once downloaded, open the file — it runs an automated installer
  5. When prompted, enter your sudo password (if you haven’t set one, go to Konsole and type passwd to create one)
  6. After installation completes, return to Gaming Mode by double-clicking the Return to Gaming Mode icon on the desktop
  7. In Gaming Mode, press the Quick Access button (… button on right side) — you should see a new plug icon at the bottom. That is Decky Loader.

Step 2: Install the Animation Changer Plugin

  1. Press the Quick Access button (…) and click the plug icon to open Decky Loader
  2. Click the Store icon (shopping bag)
  3. Search for “Animation Changer” or “BootVideos”
  4. Click Install on the plugin
  5. After installation, it appears under your Decky plugins list

Step 3: Find a Custom Boot Animation

The best sources for pre-made Steam Deck boot animations in 2026:

  • SteamGridDB — the largest community database of Steam artwork including boot animations
  • r/SteamDeck on Reddit — community members regularly share custom boot animations
  • GitHub — search “steam deck boot animation” for community-made collections
  • Create your own — use HandBrake to convert any video to WebM at 1280×800

Step 4: Transfer the Animation File to Your Steam Deck

You need to get the animation video file onto your Steam Deck. Options:

  • USB drive — plug in a USB drive via USB-C dock and copy the file
  • microSD card — copy the file to your Steam Deck’s microSD card
  • Download directly — in Desktop Mode, download the file using Firefox
  • SSH / Warpinator — transfer wirelessly from another device on the same network

Place the video file in a memorable location such as /home/deck/Downloads/ or your microSD card.

Step 5: Apply the Custom Boot Animation

  1. In Gaming Mode, press the Quick Access button (…)
  2. Open Decky Loader (plug icon)
  3. Select Animation Changer from your plugin list
  4. Browse to the location of your video file and select it
  5. Click Apply or Set as Boot Animation
  6. Restart your Steam Deck — your custom animation plays on the next boot

How to Remove or Restore the Default Boot Animation

To restore Valve’s default boot animation, open the Animation Changer plugin in Decky Loader and select Restore Default or Remove Custom Animation. The original Valve animation is restored immediately on next restart. Alternatively, uninstalling Decky Loader entirely restores all defaults.

Troubleshooting Common Issues

  • Animation not playing — check that the video is 1280×800 and in WebM or MP4 format. Use HandBrake to re-encode if needed
  • Animation plays once then reverts — the file may have been deleted or moved. Keep it in a permanent location
  • Decky Loader not loading — check for Decky updates via the Decky settings. After SteamOS updates, Decky sometimes needs to be reinstalled
  • Black screen during boot — the video file may be corrupt. Restore default and try a different file
  • Animation is stretched or distorted — resolution must be exactly 1280×800, not 16:9 aspect ratio

Frequently Asked Questions

Does installing a custom boot animation void the Steam Deck warranty?
No. Valve has confirmed that modifying software on Steam Deck does not void the warranty. Decky Loader is widely used and endorsed by the Steam Deck community.

Can I use any video as a boot animation?
Your video must be converted to WebM (VP9) or MP4 (H.264) format at 1280×800 resolution. Use HandBrake (free) to convert any video to the right format. Keep it under 8 seconds and 50MB for best results.

Does the boot animation play with sound?
No. Boot animations on Steam Deck are muted by default. The audio track in your video file will be ignored. This is a Steam Deck system limitation, not a plugin limitation.

Works on both Steam Deck LCD and OLED?
Yes. The same method works on both the original Steam Deck (LCD) and the Steam Deck OLED released in 2023. Both have a 1280×800 display resolution for the boot animation.

What is Decky Loader?
Decky Loader is a free, open-source plugin loader for Steam Deck that adds functionality to the Gaming Mode interface. It is the most widely used Steam Deck mod framework and supports dozens of plugins for themes, boot animations, fan control, and more. Installing Decky Loader does not modify SteamOS core files.
