It generates audio-driven lip-sync videos from a single portrait photo and any audio clip (speech or singing). Perfect for creating digital humans, talking avatars, or even song covers – all with minimal effort.## Key Features- 🆓 Completely free &amp; open-source – powered by [Infinite Talk](<a target="_blank" rel="ugc" href="https://github.com/your-link-here">https://github.com/your-link-here</a>)- 🎤 Audio-driven lip sync – just provide an image and audio, the model matches mouth movements perfectly- ⚡ Easy to use – simple prompt (e.g., "person talking to camera") and default 25fps setting- 🔧 Flexible duration – automatically calculates total frames based on audio; adds a safety margin (extra 1 second / 25 frames) to ensure the full audio is spoken- 🖼️ High-res output – built-in upscaling option to enhance 540p results to crisp, clear videos- 🔁 Multi‑scene support – combine with other workflows (e.g., Z image, Qianwen 2511 editing, Qianwen TTS) to create multi‑shot digital human videos with consistent characters## How It Works1. Upload your portrait image and audio file (WAV/MP3).2. Write a simple prompt – keep it straightforward (e.g., "person talking to camera"). Complex camera movements are not supported.3. Set frames – default 25fps is recommended. The workflow automatically adds an extra 25 frames to avoid audio truncation.4. Run the workflow. The core sampling node processes four inputs: - Model loader (adjust block swap if VRAM is low) - Text embeddings (understanding the prompt &amp; video dimensions) - CLIP text (positive/negative prompts – use generic negatives) - Audio embeddings (the uploaded audio, optionally truncated)5. Output a lip-synced video. If you need higher resolution, feed the result into the included upscaler.## Important Notes &amp; Limitations- ⏱️ Single‑clip duration – avoid generating videos longer than 1 minute in one go, otherwise color shift/artifacts may appear.- 🎵 Audio length – for optimal results, keep audio under 60 seconds when running on cloud platforms (e.g., RunPod). On a local machine you can run longer sessions.- 🧠 VRAM / memory – if you're running locally, increase your virtual memory and adjust the "block swap" in the model loader if you run out of VRAM.- 🖼️ Source image quality – for best final clarity, start with a high‑resolution, clean portrait. The upscaler works better with good originals.## Advanced Usage: Multi‑Scene Digital HumanTo create a more engaging video with multiple angles or scenes of the same character:1. Generate a character image (e.g., with Z image).2. Use a storyboard workflow to get scene descriptions.3. Edit the original image with Qianwen 2511 (or similar) to create consistent character variations.4. Clone a voice using Qianwen TTS (keep it ~1 minute for best naturalness).5. Run each image through this lip‑sync workflow.6. Upscale and combine the clips.The result is a professional‑looking lip‑sync video with seamless transitions and ultra‑clear visuals.## Tags<code>digital human</code>, <code>lip sync</code>, <code>infinite talk</code>, <code>audio-driven</code>, <code>talking avatar</code>, <code>comfyui</code>, <code>workflow</code>, <code>open source</code>, <code>video generation</code>, <code>face animation</code>---Get started now – it's literally "有手就会" (anyone can do it)!
