Motion Menu: Video Loader

An add-on for Motion Menu. It turns a video of your own into a menu background — pick a clip, and it becomes the thing playing behind your title screen.

Motion Menu on its own plays the backgrounds you already have: the one it ships with, and any background pack you install. This add-on is what lets you bring your own footage in. It is a separate download on purpose — a player who only ever picks a ready-made background should never have to carry a video decoder around for a feature they do not use.

What it does

Imports any clip. MP4, MKV, WEBM, MOV, AVI — or a GIF.
Asks once, then gets out of the way. Name it, choose the frame rate and the width, and press Continue.
Decodes in the background. Close the progress card and carry on using the menu; the import keeps going, and a chip at the top takes you back to it. It selects itself the moment it is finished.
Tells you when something goes wrong. A failed import gets a card that says what happened, and a button that tells you exactly how to fix it.

The decoder, handled for you

Minecraft has no video decoder, so importing needs one. This add-on gets it for you: one button downloads the official FFmpeg build for your system — Windows, macOS or Linux — straight into the mod's own folder.

Nothing is installed on your computer. Your PATH is never touched. Deleting config/motionmenu-ffmpeg/ undoes all of it, and if you already have FFmpeg installed, it is simply used and nothing is downloaded at all.

Would rather not download anything? The add-on carries a small pure-Java decoder that reads H.264 MP4 and GIF with no setup whatsoever. It is slower and it reads less, but it works offline and it asks for nothing.

Requirements

Motion Menu — this add-on does nothing on its own
Fabric Loader 0.19.0 or newer
Minecraft 26.2
Java 25
Client-side only — no Fabric API needed

How to use it

Drop this jar in your mods folder, next to Motion Menu.
On the title screen, open the gear, then Menu Background.
Press Import video or GIF... and pick your clip.
Name it, set the frame rate and width, and let it decode. That is all.

A good background is a short loop — 5 to 15 seconds — whose last frame looks like its first. Lower frame rates and smaller widths make a lighter background; 30 FPS at 1920 makes the sharpest one.
