ReFlow-Studio
Local AI desktop workstation for automated video dubbing, voice cloning, and lip synchronization.
Translate, clone voices, and sync video lip movements entirely on your local workstation.
Reflow Studio is a desktop application designed for end-to-end video dubbing, voice cloning, and lip synchronization. It combines tools like XTTS v2, RVC, Wav2Lip, and GFPGAN into a unified graphical interface for video creators. You can batch-process translations locally without relying on external cloud APIs.
What it is
Reflow Studio orchestrates multiple AI models into a local video production pipeline. It translates audio, clones voices using RVC, realigns lip movements with Wav2Lip, and sharpens face details via GFPGAN. It also includes UVR5 stem separation to isolate background audio and built-in controls to clear render caches.
Who it's for
This workstation suits video editors, content creators, and localizers who need to translate video content while preserving background audio. It requires a workstation with a dedicated NVIDIA GPU for reasonable processing times. It is not intended for users who want cloud-based rendering or lightweight web apps.
Key features
Zero-dependency portable setup
Runs from a portable directory with embedded Python and FFmpeg binaries to avoid system configuration issues.
Voice cloning pipeline
Pairs XTTS v2 text-to-speech with Retrieval-based Voice Conversion to mirror original speaker voices.
Automated lip synchronization
Re-aligns target mouth movements to match newly generated dubbed audio using Wav2Lip and GFPGAN.
Background audio preservation
Uses UVR5 stem separation to isolate background tracks so original music remains behind dubbed speech.
System reset tools
Provides a hard process kill button and cache wiper to unfreeze stuck render tasks and clear disk space.

Our honest verdict
What's great
- Runs locally on your desktop to maintain complete data privacy without cloud API fees.
- Bundles pre-configured FFmpeg binaries and portable runtime scripts for easy launch on Windows.
- Includes UVR5 audio separation so background music and sound effects are preserved during dubbing.
- Features dedicated janitor tools to terminate frozen render loops and wipe local caches.
Where it falls short
- Requires a modern NVIDIA GPU with CUDA support for practical execution speeds.
- Downloads roughly 2GB of model weights on first startup before running offline.
- Consumes significant local VRAM and system memory during combined face restoration tasks.
- Portable launcher scripts are primary to Windows, requiring manual setup on other OS platforms.
Pricing & license
Reflow Studio is open-source and free to download under the MIT license. Running costs depend entirely on your local hardware resources, electricity, and initial setup requirements.

FAQ
Does Reflow Studio require an active internet connection?
An internet connection is required on the first launch to download AI model weights. Subsequent processing runs entirely offline.
What hardware is needed to run this application?
An NVIDIA GPU supporting CUDA 11.8+ is strongly recommended, although CPU safe mode is available for fallback execution.
How does the software handle background music in videos?
It uses UVR5 stem separation to strip vocal tracks from background music before generating and overlaying the dubbed voice.
