Stage 2 Configurator

SadTalker Settings Starting Points

This finder uses the same rules as the Settings Finder. It suggests starting points for your inputs. See the Best Settings master guide for captured settings evidence and limitations.

Choose your photo type, audio recording qualities, and production goal. The finder suggests settings to try; it cannot predict or prevent distortion, jitter or GPU memory errors. Inspect a short render first.

Planning Local Setup on Your Own PC?

Our captured GPU comparisons use NVIDIA CUDA. Memory requirements vary with the input, software and settings; these card capacities are not guaranteed minimum requirements.

4GB VRAM (Check before use)Start with 256, batch size 1 and enhancement OFF. This guide does not establish successful execution or render times on every 4GB card.
12GB VRAM (Measure your setup)More capacity can help, but successful 512 + GFPGAN execution is not guaranteed. Monitor device usage and compare with the separately documented test setup.
24GB VRAM (High Performance)RTX 3090 / RTX 4090. The linked standalone test measured 40.490s on the RTX 4090 for its specific clip and settings. The ComfyUI isolated-worker tests have different timings.

Frequently Asked Questions

Can I test SadTalker for free without coding?

Yes! The official Hugging Face Space offers a zero-code web interface where you can drag and drop your photo and voice track. You can also run the 1-click Google Colab notebook completely in the cloud.

What does the GFPGAN enhancer do?

SadTalker’s 3DMM renderer generates facial movement at 256×256 or 512×512. When the --enhancer gfpgan flag is included, each output frame is passed through optional GFPGAN restoration. It may sharpen eyes and facial hair or smooth skin, but it can also generate altered texture and teeth. Compare the output against the original likeness.

Why should I use the --still flag?

By default, SadTalker simulates natural head tilting and breathing motions. For educational courses, corporate explainers, or news broadcasts, excessive swaying can distract viewers. The --still flag locks the torso and neck in place so all motion is dedicated to expressive lip-sync and eye movement.

How long does it take to generate a video?

Generation times depend primarily on your GPU and whether GFPGAN face enhancement is enabled. In our verified hardware benchmarks for an 11.24-second audio clip (281 frames at 512px with GFPGAN):

  • NVIDIA RTX 4090 (24GB): 40.490 seconds (10.60 it/s enhancer speed)
  • NVIDIA RTX 3090 (24GB): 130.135 seconds (2m 10s) (2.75 it/s enhancer speed)
  • NVIDIA RTX 3060 (12GB): ~195 seconds (~3m 15s) (~1.9 it/s enhancer speed)
  • Fast 256px Mode (No enhancer): Under 15s on RTX 4090; ~42s on RTX 3060.
