The article walks readers through installing the lightweight video editor Avidemux on Ubuntu 22.10, 22.04 LTS, and 20.04 using three popular methods: Snap, apt from the default repository, or Flatpak. It explains why each package manager is useful; Snap offers quick installation and automatic updates with a classic confinement flag, the Ubuntu repo provides a signed, theme‑integrated version, while Flatpak bundles all dependencies for newer builds. The guide includes step‑by‑step command snippets, practical tips like verifying the install via the --version flag, and a sanity check that tests cutting a clip without codec errors. By sharing real‑world anecdotes of users who struggled with “invalid format” errors before switching to Snap or Flatpak, the post reassures newcomers that getting Avidemux up and running on these Ubuntu releases is straightforward and reliable.

How to Install Avidemux on Ubuntu 22.10, 22.04, and 20.04 – Quick & Reliable

If you’re tired of fiddling with GStreamer codecs when trimming a clip, Avidemux is the lightweight, cross‑platform editor that gets the job done without a PhD in video compression. In this guide I’ll walk you through installing it on Ubuntu 22.10, 22.04 LTS, and the still‑popular 20.04.

1. Install Avidemux with Snap (works everywhere)

Snap is Apple‑like for Linux: one command and you’re done.

sudo snap install avidemux-gtk --classic

Why this matters:

• The --classic flag lets the package access your file system, which Avidemux needs to read and write video files.
• Snap keeps Avidemux updated automatically—no more hunting for new releases on the website.

> I had a buddy stuck in 22.04 who tried editing a 4‑minute home movie and kept getting “invalid format” errors until they installed the snap version. The first time she ran it, she didn’t even notice the difference.

2. Install from the Ubuntu repository (no Snap)

For those who like to stay in the default package ecosystem:

sudo apt update
sudo apt install avidemux-gtk

Why this matters:

• The repository version is signed by Canonical, so you’re not pulling software from a random site.
• It integrates with your system’s theme and file‑type associations automatically.

> On 20.04 I once pulled the repo package and discovered that it shipped an older build that didn’t support MP4‑x264. The snap version fixed that in seconds.

3. (Optional) Use Flatpak for a newer build

If you prefer Flatpak or want access to the latest Avidemux without waiting for the repository:

sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub com.github.avidemux.Avidemux

Why this matters:

• Flatpak bundles all dependencies, so you don’t run into missing libraries on a fresh 22.10 system.
• You can keep the snap and flatpak versions side by side if you want to test both.

4. Verify the installation

Open a terminal and type:

avidemux-gtk --version

You should see something like Avidemux 2.7.10 printed out. If it doesn’t launch from the Dash, try running avidemux-gtk directly; the command line often reveals missing runtime dependencies.

5. Quick sanity check

1. Launch Avidemux (avidemux-gtk).
2. Drag a video file into the window.
3. Try cutting a segment with Edit => Cut and then File => Save.
4. If it runs without throwing “invalid format” or “cannot open codec,” you’re good to go.

Give it a whirl, and happy editing.
