Made with this app
How it works
SadTalker turns a single photograph and a short audio clip into a lip-synced talking-head video, delivered as an MP4 at up to 512x512 resolution. Built for speed and affordability, it suits creators who need to test scripts, prototype explainer videos, or produce avatar content on a tight budget. Expression control lets you shape how the face moves beyond basic lip sync, giving you a meaningful degree of creative direction without the cost or wait time of heavier pipeline models.

What you can make
Script and Concept Testing
Before committing to a high-cost production run, drop a rough voiceover and a headshot into SadTalker to verify that pacing, tone and facial movement feel right. The fast turnaround means you can run several versions in the time it would take a heavier model to finish one.
Budget Explainer Videos
Small businesses and solo creators who need a talking spokesperson without hiring talent can upload a portrait and record up to 30 seconds of narration. The result is a clean MP4 ready for social media, slide decks or product pages.
Rapid Prototype Reels
Agencies pitching avatar-based campaigns can generate multiple character options from different photos in quick succession. Expression control allows each version to carry a slightly different emotional register, giving clients real choices to react to during early reviews.
E-learning Placeholder Content
Course developers often need a talking-head clip to stand in while final assets are being approved. SadTalker produces a usable, lip-synced placeholder quickly, keeping the production schedule moving without locking budget into polished footage too early.
Personal Social Content
Individuals who want an animated avatar for short-form posts can animate a stylized portrait or illustrated character. The single-photo input keeps the workflow simple, and the affordable price point makes casual, frequent use practical.
Prompt ideas to try
- Animate this professional headshot with the attached 20-second product pitch audio, keeping the expression calm and confident throughout.
- Use this illustrated character portrait and the provided voiceover to create a lip-synced avatar with a slightly surprised facial expression.
- Generate a talking-head clip from this passport-style photo and a 15-second script read, targeting a neutral corporate expression.
- Animate this stylized cartoon face with the uploaded podcast intro audio, using an upbeat, engaged expression setting.
- Create a spokesperson clip from this studio portrait and a 28-second narration track for use as a website header video.
- Produce a quick test render of this customer avatar photo synced to a 10-second sample voiceover so I can check lip-sync accuracy before final production.

Tips for better results
Choose a Clean, Frontal Photo
SadTalker works from a single image, so photo quality directly shapes output quality. Use a well-lit, forward-facing portrait with a simple background and minimal occlusion of the face. Avoid heavy shadows, extreme angles or sunglasses, which can confuse the facial landmark detection.
Keep Audio Under 30 Seconds
The model has a firm 30-second audio limit. Trim your clip in advance and ensure the speech starts promptly without long silent lead-ins. Clean, mono audio with minimal background noise produces tighter lip sync than a busy mix or a clip recorded in an echoey room.
Use Expression Control Deliberately
Expression control is one of SadTalker's differentiating features. Match the expression setting to the emotional register of the audio: a neutral setting suits corporate narration, while a more animated setting fits conversational or enthusiastic scripts. Mismatches between voice tone and face expression read as unnatural.
Treat 256x256 as a Draft Resolution
If your final deliverable needs the sharpest result the model can produce, render at 512x512. Reserve 256x256 for fast iteration rounds where you are checking timing and expression rather than final pixel quality. This keeps your review cycles short and reserves higher-resolution renders for approved takes.
When to choose this app
Choose SadTalker when speed and cost matter more than maximum output resolution. If you need a polished 4K lip-sync pass on existing footage, Sync-3 Lipsync is the right tool for that workflow. If your priority is versatile lip sync across a wide range of character types, Kling Avatar v2 addresses that need. SadTalker's advantage is the combination of fast generation, expression control and a budget-friendly price point that makes high-volume testing and low-stakes production genuinely practical.
Frequently asked questions
What file formats does SadTalker accept for the photo and audio inputs?
The app accepts a standard portrait image for the photo input. For audio, upload a clean clip of up to 30 seconds. The output is always delivered as an MP4 video file. Check the upload interface for the specific file type extensions supported at the time of your session, as accepted formats can be updated.
Can I animate an illustrated or cartoon character, or does it only work on photographic faces?
SadTalker can animate illustrated and stylized faces as long as the facial landmarks, eyes, nose and mouth are clearly defined and roughly frontal. Highly abstract art styles with ambiguous facial geometry tend to produce less accurate lip sync, so a semi-realistic illustration generally works better than a minimalist design.
How does expression control work, and what options are available?
Expression control lets you influence the amplitude and style of facial movement beyond basic lip sync. You can push the face toward a more neutral or a more animated register depending on the emotional tone you need. The specific controls available are presented in the app interface at generation time.
Is 512x512 sufficient for use in a finished video production?
At 512x512, the output is suitable for web video, social media posts, slide presentations and embedded website clips viewed at standard sizes. For large-screen broadcast or print-adjacent use cases where a talking head fills a significant portion of the frame, you may find the resolution limiting and should evaluate a higher-resolution option.
What happens if my audio clip is longer than 30 seconds?
The model will not process audio that exceeds the 30-second limit. Trim your clip to 30 seconds or under before uploading. If your script is longer, split it into segments, generate separate clips for each, and join them in a video editor after the fact.
Does the quality of the input audio affect the accuracy of the lip sync?
Yes, meaningfully. Clear, close-mic speech with minimal background noise gives the model the cleanest phoneme signal to work from, which produces tighter lip sync. Noisy, reverberant or heavily compressed audio can cause the model to misread certain sounds, leading to visible mismatches between mouth movement and speech.
How much does it cost?
Each generation costs 5 credits. New accounts get free credits to try it out.
Which AI model powers this app?
This app runs on SadTalker, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
