Can 20 GitHub repositories add up to a whole motion studio?
From React video, 3D, and audio to FFmpeg export, this list covers most stages of motion production. It also mixes libraries, models, MCPs, and desktop tools; don't treat them as the same layer.
A tweet lines up 20 GitHub projects into a motion pipeline, and includes a demo video. Watch the video first.
The list comes from rachit. His original words were “un estudio de motion entero en skills 100% gratis de GitHub.” Translated, that's a complete motion studio built entirely with free open-source skills from GitHub. The list is aimed at Opus 5.5, but it mixes animation libraries, 3D libraries, physics engines, models, MCPs, and desktop tools. Treating them as the same kind of thing will get messy; breaking them down by production stage makes it clear.
Video and animation
01 Remotion, write videos with React.
http://github.com/remotion-dev/remotion
02 Remotion Skills, official video skills for agents.
http://github.com/remotion-dev/skills
03 Anime.js, choreograph animations with timelines.
http://github.com/juliangarnier/anime
04 Motion, for UI animation and layout transitions.
http://github.com/motiondivision/motion
05 Manim, for charts, equations, and explanatory animations.
http://github.com/ManimCommunity/manim
06 Lottie, lightweight vector animations.
http://github.com/airbnb/lottie-web
3D, physics, and visual processing
07 MCP for Blender, lets Claude build and edit 3D scenes.
http://github.com/ahujasid/mcp-for-blender
08 Three.js, for 3D scenes and camera movement.
http://github.com/mrdoob/three.js
09 Three GPU Pathtracer, for realistic lighting and reflections.
http://github.com/gkjohnson/three-gpu-pathtracer
10 Jolt Physics, handles collisions, rigid bodies, and soft bodies.
http://github.com/jrouwe/JoltPhysics
11 postprocessing, adds bloom, depth of field, and color grading.
http://github.com/pmndrs/postprocessing
12 Three.quarks, for particles and VFX.
http://github.com/Alchemist0823/three.quarks
13 Tweakpane, tweak scene parameters live.
http://github.com/cocopon/tweakpane
Generation and sound
14 ComfyUI, build generative workflows with nodes.
http://github.com/Comfy-Org/ComfyUI
15 CosyVoice, for multilingual voiceover.
http://github.com/QwenAudio/CosyVoice
16 librosa, detect beats and make animations follow the music.
http://github.com/librosa/librosa
17 WhisperX, for word-level timestamped subtitles.
https://github.com/m-bain/whisperX
Capture, editing, and export
18 OBS Studio, screen recording.
http://github.com/obsproject/obs-studio
19 LosslessCut, fast cutting without re-encoding.
http://github.com/mifi/lossless-cut
20 FFmpeg, encoding and final export.
http://github.com/FFmpeg/FFmpeg
The truly useful part of this list is the production order. Stefan Friedman boils it down to one line: idea, scene, motion, sound, cut—that's the whole job.
Several points mentioned in the replies are also specific. One user said LosslessCut saved them hours, but not many people discuss it. Another said WhisperX plus Remotion is a cheat code for short videos. Another user latched onto Remotion Skills plus Opus 5.5, saying that's exactly the combination they were looking for. rachit himself replied that he is still paying for After Effects templates.
What's free is the code; the costs are in the learning curve, compute, and maintenance. Generative stages like ComfyUI and CosyVoice also need models and compute. MCP for Blender requires Blender first. OBS, LosslessCut, and FFmpeg are desktop tools, not agent skills. A few items on the list can directly replace repetitive work in traditional workflows, such as parametric re-rendering, word-level subtitles, beat-synced animation, and fast cutting without re-encoding.
The original tweet and Chesny's article are below. You don't need to install all 20 repositories at once; picking one stage to replace first is more realistic than starting everything from the full list.
