Generate videos from text prompts (and optional reference or frame images) using Letta's asynchronous video generation API. Use when the user asks to create, generate, or make a video or animation from a description, animate an existing image, or turn a prompt into a short video clip.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Video Generation
Generate videos via Letta's async `POST /v1/videos` using `curl` + `jq`. Requires `LETTA_BASE_URL` and `LETTA_API_KEY`, which the runtime provides. If either is unset, stop and ask the user to authenticate with Letta Cloud; do not ask for a video provider key.
This skill is adapted from OpenRouter's `openrouter-video` skill
([OpenRouterTeam/skills](https://github.com/OpenRouterTeam/skills/blob/83827c3f3b1200bc3b609f4ab4ec3241c0cfb7ad/skills/openrouter-video/SKILL.md)).
Letta's endpoint forwards the request with Letta's key and charges the
organization's Letta credits for the cost of each completed video.
Build every URL relative to `${LETTA_BASE_URL%/}` and send `Authorization: Bearer $LETTA_API_KEY`. Do not hardcode `https://api.letta.com`: Desktop and remote runtimes may provide a proxy base URL, and the credential may only be valid through that URL.
## The three steps
Video generation is async: submit → poll → download. A single request can't return the video because generation takes 30s–a few minutes. Tell the user the job was submitted so they know the delay is expected.

How to install
mdr add letta-ai/letta-code/video-generation@sha256:7e060565c67a2f06The line at the top of this page pins the label git:20261029.85a703f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
