- Free allowance
Not separately confirmed. Check the current plan before relying on a free allowance.
- Best suited to
Automatic1111 users who want lip-sync video generation, since the extension adds Wav2Lip lip-sync with a choice of accurate lip-sync or better visual quality with GAN.; Creators who want enhanced output, since GFPGAN is offered as an option and generation can be resumed, with quality tips documented in the README.

What to know before choosing
Good fit
Automatic1111 users who want lip-sync video generation, since the extension adds Wav2Lip lip-sync with a choice of accurate lip-sync or better visual quality with GAN.; Creators who want enhanced output, since GFPGAN is offered as an option and generation can be resumed, with quality tips documented in the README.
Limits and trade-offs
Users without an Automatic1111 install, since the project is an extension for Automatic1111, not a standalone application.; Users who need real-time lip-sync, since the extension generates lip-sync videos as a batch process inside WebUI.

A closer look at Wav2Lip for Automatic1111
Wav2Lip for Automatic1111, repository sd-wav2lip-uhq, is an extension for Automatic1111 that generates lip-sync videos. It offers Wav2Lip for highly accurate lip-sync and Wav2Lip plus GAN for slightly inferior lip-sync with better visual quality, with s3fd face detection models, GFPGAN enhancement as an option, and experimental face swap through facefusion integration. Model weights are downloaded separately into the extension's checkpoint folders, and the repository lists an Apache-2.0 license.

When to choose Wav2Lip for Automatic1111
- Automatic1111 users who want lip-sync video generation, since the extension adds Wav2Lip lip-sync with a choice of accurate lip-sync or better visual quality with GAN.
- Creators who want enhanced output, since GFPGAN is offered as an option and generation can be resumed, with quality tips documented in the README.
When to choose something else
- Users without an Automatic1111 install, since the project is an extension for Automatic1111, not a standalone application.
- Users who need real-time lip-sync, since the extension generates lip-sync videos as a batch process inside WebUI.
A practical starting workflow
- Install the sd-wav2lip-uhq extension inside Automatic1111.
- Download the model weights for Wav2Lip, Wav2Lip plus GAN, and s3fd face detection, and place them in the matching checkpoint folders.
- Open the Wav2Lip tab, provide the video and audio, and generate the lip-sync video.
- Enhance the output with GFPGAN where wanted, and resume generation if it is interrupted.
Check before committing
- Model weights must be downloaded separately and placed in the matching checkpoint folders, with care for filenames, especially for the s3fd face detection model.
- Face swap through facefusion integration is described as experimental, so it should not be relied on for production work.
- The extension runs inside Automatic1111, so a working Stable Diffusion WebUI install is a prerequisite.
Common questions
What is Wav2Lip for Automatic1111?
Wav2Lip for Automatic1111 is the sd-wav2lip-uhq extension for Automatic1111 that generates lip-sync videos, with Wav2Lip and Wav2Lip plus GAN models, GFPGAN enhancement, and experimental face swap.
How are model weights installed?
Download the model weights and place them in the matching directories, taking care with filenames, especially for s3fd face detection, under the extension's wav2lip checkpoints folder.
What license does the extension use?
The repository page lists an Apache-2.0 license, and the license fact covers the software license only, not hosting or compute.
Is it a standalone app?
No. It is an extension for Automatic1111, so it runs inside a Stable Diffusion WebUI install rather than as a standalone app.
