About DeepFaceLab
DeepFaceLab is the dominant open-source deepfake tool responsible for over 95% of deepfake videos worldwide. It is completely free, runs on Windows and Linux, and delivers cinema-quality face swaps through a multi-step pipeline of face extraction, model training, and video composition. Requires an NVIDIA GPU with CUDA for optimal performance (6-24+ GB VRAM recommended). The learning curve is steep, but extensive community resources and pretrained models help beginners get started.
Best for: VFX professionals, researchers, and dedicated hobbyists who need cinema-quality face swapping and are willing to invest in hardware and learning time for unmatched results.
“DeepFaceLab is the gold standard for face-swapping software, delivering cinema-quality results for free. The steep learning curve and GPU requirements are significant barriers, but no other tool matches its output quality. Essential for VFX professionals and serious deepfake hobbyists.”
What is DeepFaceLab?
Overview
DeepFaceLab is the undisputed standard in face-swapping software, powering more than 95% of all deepfake videos created worldwide. Developed by iperov and maintained by an active community, this free and open-source tool enables users to swap faces in videos with remarkable realism. Available on GitHub, it runs on Windows and Linux systems and leverages deep learning neural networks to analyze, extract, train on, and replace faces in video footage.
Unlike cloud-based or real-time face swap tools, DeepFaceLab operates entirely offline as a local application. This means complete privacy over your data, but also significant hardware requirements and a substantial time investment for training.
Key Capabilities
DeepFaceLab follows a structured pipeline approach to face swapping. The workflow begins with video decomposition into individual frames, followed by face detection and extraction using neural networks. Extracted faces are aligned and processed for training. The core training phase uses deep learning models (SAEHD, Quick96, and others) to learn facial mappings between source and destination faces. Finally, trained models are applied to destination frames, which are reassembled into video.
The software offers multiple model architectures with configurable parameters including resolution, batch size, and training iterations. Users can adjust dozens of settings to balance quality against training time. Pretrained models and celebrity facesets available from the community can jumpstart projects and reduce training time from days to hours.
Advanced features include color correction, seamless blending, mask editing, and interactive merge tools that give fine-grained control over the final output. The MVE Community Fork adds additional features and improvements on top of the base software.
Technical Requirements
DeepFaceLab demands serious hardware. An NVIDIA GPU with CUDA support is strongly recommended, with 6-24+ GB of VRAM determining the model resolution and training speed achievable. RTX-series cards are ideal. A modern multi-core CPU, 16+ GB of RAM, and 50+ GB of free disk space are needed for projects. CPU-only training is possible with AVX instruction support but is dramatically slower.
Windows 10 or later is the primary platform, though Linux is supported. Enabling Hardware Accelerated GPU Scheduling in Windows settings can improve performance. The software does not require a traditional installation; you download, extract, and run batch files.
Who Should Use This
DeepFaceLab is for VFX professionals working on film and video post-production, researchers studying face synthesis and detection, hobbyists creating entertainment content, and digital artists exploring face manipulation as a creative medium. The software requires patience, technical comfort with command-line-adjacent workflows, and willingness to invest hours or days in training.
Casual users looking for quick face swaps should consider simpler alternatives like Reface or FaceApp. Users without NVIDIA GPUs will struggle with performance. Anyone expecting real-time or one-click results will find DeepFaceLab's pipeline approach demanding.
The Bottom Line
DeepFaceLab remains the gold standard for face-swapping software in terms of output quality. Nothing else in the free or open-source space comes close to its cinema-quality results when properly configured and trained. The trade-offs are a steep learning curve, significant hardware requirements, and time-intensive training processes. For users willing to invest the effort, the results are unmatched.

How to Use DeepFaceLab
- 1Download DeepFaceLab
Visit the GitHub repository or deepfakevfx.com and download the build matching your GPU (NVIDIA CUDA, AMD, or CPU-only). RTX-series builds offer the best performance.
- 2Extract and Set Up
Unzip the downloaded archive to a local folder. No installation is needed. Optionally download pretrained models and celebrity facesets to accelerate your first project.
- 3Extract Video Frames
Place your source video (face to swap in) and destination video (face to replace) in the workspace folder, then run the frame extraction batch files to decompose videos into images.
- 4Extract and Align Faces
Run face extraction scripts to detect, crop, and align all faces from the extracted frames. Review the results and remove any misdetected or low-quality face crops.
- 5Train the Model
Run the training batch file to start the deep learning process. Monitor the loss values and preview window. Training typically takes 12-48 hours for high-quality results.
- 6Merge and Export
Apply the trained model to destination frames using the merge tool, adjust color correction and blending settings interactively, then convert the final frames back into a video file.

Limitations
DeepFaceLab requires significant hardware (NVIDIA GPU with 6+ GB VRAM recommended) and training time (hours to days per project). There is no real-time processing capability. The batch-file workflow lacks a modern GUI. CPU-only training is technically possible but impractically slow. The software is Windows-primary, with Linux as a secondary platform. Ethical and legal considerations apply to face-swap content.
