Mortiflix Oss

Mortiflix Oss is a motion design studio software that generates videos step by step with Claude while allowing human review at each stage.

Mortiflix is a motion design studio tool that operates locally on the user machine to produce videos step by step. Claude handles video creation through either a Claude Code login or an Anthropic API key, while the user reviews and approves each stage including briefs, scripts, style frames, transitions, animatics, and final renders. Projects move through pipelines containing steps, error checks, and craft guidelines. The system supports multiple narration options such as ElevenLabs, Qwen3-TTS via ComfyUI, user recordings, or text and music only. It builds videos using Remotion and verifies outputs with ffmpeg. Users can create explainers, social shorts, and logo stings.
