How to Make a Faceless YouTube Short From a Script With AI Voice and Captions (No GPU, Open Source)

A faceless Short is a vertical video with a voiceover, a headline and captions but no person on camera. faceless-shorts is an open-source (MIT) Agent Skill that turns a short scene script into a finished 1080x1920 MP4: each scene is voiced through the Miragea speech API, its length is set from the real audio, and word-highlight captions are burned in. It needs only Python and ffmpeg: no GPU, no stock-footage key, no second LLM key. 1. Write the script {"scenes": [ {"id": "hook", "keyword": "Honey never spoils", "text": "Here is a food that never goes bad. Honey."}, {"id": "why", "keyword": "Why?", "text": "It is so dry and so acidic that bacteria simply cannot grow in it."}, {"id": "cta", "keyword": "Follow for more", "text": "Follow for one tiny fact every day."} ]} 2. Estimate, then make git clone https://codeberg.org/miragea-voice/miragea-skills && cd miragea-skills export MIRAGEA_API_KEY=... # create one at https://miragea.ai/workspace/api python3 skills/faceless-shorts/scripts/shorts.py script.json --voice "Ava" --dry-run python3 skills/faceless-shorts/scripts/shorts.py script.json --voice "Ava" --theme sunset -o short.mp4 Unchanged scenes are cached by hash, so editing one line only re-voices that line. No saved voice? Clone one from a public sample with --reference-audio-url and --reference-text. Real result A 17-second honey-facts Short made exactly this way. Speech recognition on the final MP4 returns the script word for word.

The agent writes the scenes and runs the script. Agent install line: Install https://miragea.ai/skills/miragea-audio/install.md. FAQ Does it need a GPU? No. Voice comes from an API; video is drawn by ffmpeg. Can I use my own images? Yes, add "image": "photo.jpg" to a scene for a slow zoom.
