AI Mastodon Video Maker: Generate Videos for Mastodon and the Fediverse

Mastodon's video post format accepts standard MP4 files — the same format MakeThisVid generates. For creators, brands, and communicators building a presence on Mastodon and the Fediverse, short video posts get significantly more boost and engagement than text-only toots. MakeThisVid generates an 8-second 1080p clip from a text description in under two minutes. Download and attach directly to a post.

How to Use MakeThisVid

From prompt to downloadable MP4, ready to deploy.

  1. Pick a plan or credit pack

    Lite ($14.99/mo, 20 credits), Standard ($29.99/mo, 50 credits), Pro ($79.99/mo, 200 credits). One-time packs start at $9.99 for 5 credits — no subscription required.

  2. Choose your input mode

    Text → Video: describe the scene, concept, or visual idea. Photo → Video: upload an image (JPG/PNG/WebP, max 10 MB) to animate.

  3. Write your prompt

    Describe what you want to show. Keep it specific: environment, mood, movement. E.g. "Open-source software team collaborating in a bright office, friendly and productive, warm natural light, medium tracking shot."

  4. Generate at 720p or 1080p

    1 credit per 720p video, 2 credits per 1080p. Most renders complete in 45–90 seconds. Credits refund automatically on failure.

  5. Attach to your Mastodon post

    Download the MP4 and attach it to a toot in your Mastodon client. Most instances accept MP4 up to 40MB — MakeThisVid's 8-second clips are well within that limit.
