Hermes AI Video Generator: Complete Guide to the New Manim Skill

The Hermes AI video generator just became my favourite free AI release of the week — and this is the complete guide to understanding, installing, and using it properly.

Nous Research added a Manim skill to the Hermes agent that transforms it from "useful AI assistant" into "legitimate video production tool."

One prompt produces a fully animated explainer video.

No animator required.

No After Effects needed.

No subscription fees.

Let me walk you through everything you need to know.

Part 1: Understanding the Hermes AI Video Generator

What It Actually Is

The Hermes AI video generator isn't a standalone tool.

It's a skill for the Hermes AI agent.

Think of skills as expandable capabilities — Hermes can use a skill to do a specific type of task.

The new video skill integrates Manim — an animation engine created by Grant Sanderson (3Blue1Brown) for educational math videos.

What Is Hermes?

Hermes is Nous Research's open-source AI agent framework.

Key characteristics:

Open-source and free
Model-agnostic (works with various LLMs)
Skill-based architecture for expandability
Active development (currently v0.9)
Growing community

If you're new to Hermes, start with my Ollama + Hermes setup guide.

What Is Manim?

Manim (Mathematical Animation Engine) is a Python library that creates precise animations via code.

It powers 3Blue1Brown's famously beautiful math videos.

Technical specs:

Python-based
Code-driven animations (not AI-generated visuals)
Supports text, shapes, equations, transformations
Exports to various video formats
Extensible with plugins

How They Combine

The new skill lets Hermes write Manim code automatically.

You describe what you want.

Hermes plans, writes, renders, and outputs.

Part 2: Setup and Installation

Prerequisites

Before installing, make sure you have:

Hermes agent installed and working
Python 3.10 or higher
Terminal/command line access
Basic Hermes familiarity (how to launch, give prompts)

Step-by-Step Installation

Step 1: Update Hermes to the latest version

hermes update

This ensures you have compatibility with the new skill.

Step 2: Install Manim

pip install manim

Python's package manager handles most of it.

Step 3: Install system dependencies

Manim needs some native dependencies for rendering.

On macOS:

brew install cairo ffmpeg

On Linux:

sudo apt install libcairo2-dev ffmpeg texlive-full

On Windows:

Install MiKTeX from miktex.org
Install FFmpeg from ffmpeg.org
Add both to your system PATH

Step 4: Verify the installation

Launch Hermes:

hermes

Test with a simple prompt:

Create a Manim animation of a circle morphing into a square

If Hermes successfully renders an MP4, you're ready.

Common Installation Issues

Issue: "Manim command not found"

Fix: Ensure pip install succeeded, restart terminal

Issue: "LaTeX not found"

Fix: Install texlive-full or MiKTeX

Issue: "Cairo library missing"

Fix: Install system dependencies for your OS

Issue: Rendering fails silently

Fix: Check FFmpeg is in PATH, try a simpler test prompt

Part 3: Your First Video

Anatomy of a Good Prompt

The best Hermes video prompts include:

Topic — what the video covers
Length — how long you want it (default 60-90s works well)
Target audience — technical level, age, knowledge
Style — formal, playful, corporate, educational
Brand specifics — colours, fonts if branded

Example Starter Prompts

Example 1: Technical explainer

Create a 60-second Manim animation explaining how HTTP requests work to mid-level developers. Include animated diagrams showing client-server interaction, request headers, and response flow. Use dark background with cyan and orange highlights.

Example 2: Business concept

Make a 45-second animated explainer about ROI calculation for small business owners. Show formulas building on screen, include a worked example with £10,000 investment, use warm brand colours #f59e0b and #ef4444.

Example 3: Process visualisation

Create a 90-second Manim video showing a lead's journey through our sales funnel. Start with awareness stage, move through consideration, decision, and purchase. Animate numbers showing conversion rates at each stage. Professional corporate styling.

What Happens After You Prompt

Hermes loads the Manim skill and reviews references
Plans the video — topic, hook, target audience, length, scene breakdown
Presents the plan for your review
Writes Python code for each scene
Renders individual scenes
Stitches them into final output
Provides file path to the output video

Iterating Your Output

After first render, you can refine:

"Make the intro shorter"
"Change the colour scheme to match our brand"
"Add a section about X"
"Export at 1080p"
"Speed up the transitions"

Hermes adjusts and re-renders.

Part 4: Advanced Techniques

Brand Integration

Specify brand elements explicitly:

Use brand colours: primary #f59e0b, secondary #ef4444, background #0a0a0f
Use brand font: Inter (fallback to system sans-serif)
Brand tone: confident, direct, action-oriented

Hermes applies these to every generated video.

Output Quality Control

Default quality: lower resolution, faster render 1080p export: higher quality, longer render time 4K export: highest quality, significant render time

Specify in your prompt: "Export at 1080p"

Composition Techniques

For better videos, structure your prompts with:

Hook (5-10 seconds of attention grabber)
Main content (bulk of the video)
Summary (concise takeaway)
CTA (if applicable)

Tell Hermes explicitly: "Structure as hook + main content + summary."

Combining With Other Skills

The Manim skill becomes powerful combined with:

Research skills — Hermes researches topics then animates them
Math reasoning — solve problems and animate the solutions
Memory systems — pull context from prior conversations into videos

For context on how OpenClaw Byterover's memory system works similarly, that article goes deep on persistent context.

Part 5: Real Examples and Community Outputs

Example: Jordan's Lemma (Math)

User Jean (Prompt Terminal) combined:

Manim skill (animation)
Math reasoning tool (problem solving)
Claude Sonnet (orchestration)

Result: Fully animated explainer of Jordan's Lemma from one prompt. Professional quality, rigorous correctness.

Example: GPU Kernel Explainer (Tech)

User Subho Ghosh created a GPU kernel breakdown — genuinely complex technical content — rendered as a polished animated video from a single prompt.

What This Demonstrates

The Hermes AI video generator handles real technical content
Output quality is production-grade
Single prompts produce complete videos
The tool has serious professional applications, not just demos

Hermes AI Video Generator: Frequently Asked Questions

Is there a learning curve for using the Hermes AI video generator?

Moderate. The installation takes 30-60 minutes if you're not already familiar with Python environments. After setup, it's prompt-based — which is easy to learn but takes practice to master.

What's the maximum video length the Hermes AI video generator can produce?

Technically unlimited, but practically videos over 3-5 minutes take substantial render time. For most use cases, 30-90 second videos hit the sweet spot of quality vs speed.

Can I edit Hermes-generated videos after creation?

Yes. Hermes outputs standard MP4 files you can edit in any video editor. You can also edit the generated Manim Python code directly for precise adjustments.

Does the Hermes AI video generator work with non-English content?

Yes. Manim handles Unicode text, and Hermes can generate non-English scripts. Mathematical notation is universally handled.

How secure is my content when using the Hermes AI video generator?

All rendering happens locally on your machine. Only your AI model queries (to whichever LLM provider you're using) leave your machine. For fully private workflows, use local models via Ollama.
