Made with this app
How it works
Infini Talk turns a single photograph and an audio clip into a fully animated talking avatar video, exported as an MP4 at up to 720p. Designed for creators who need expressive, lip-synced presenters without a camera or studio, it accepts any portrait photo alongside audio up to 28 seconds and produces natural head movement and facial animation driven entirely by the sound. It suits educators, marketers, indie developers, and anyone building presenter-style content from still imagery.

What you can make
Course Intro Presenters
Upload a professional headshot and a recorded course introduction. Infini Talk animates the portrait with expressive motion synced to every word, giving online courses a polished human presenter without requiring on-camera recording or video editing skills.
Multilingual Product Demos
Record the same spokesperson audio in multiple languages, then run each clip through Infini Talk with the same photo. You get a consistent brand face delivering localized demos, all from one still image and region-specific audio files.
Social Media Announcement Clips
Pair a brand mascot illustration or a founder photo with a short announcement audio clip under 28 seconds. The resulting MP4 drops directly into Instagram Reels, LinkedIn, or TikTok as an eye-catching talking-head post.
Prototype AI Companion Characters
Developers building chatbot interfaces or game NPCs can use a concept-art portrait alongside scripted dialogue audio to produce realistic avatar previews, validating character design and voice tone before committing to full production pipelines.
Internal Training Narration
HR and L and D teams can animate a trainer photo with recorded policy walkthroughs, producing reusable video segments for onboarding decks without scheduling presenter time or renting a recording studio.

Tips for better results
Choose a Front-Facing Portrait
Infini Talk derives all motion from a single image, so a clear, front-facing photo with good facial visibility produces the most accurate lip sync and expressive movement. Profile angles or heavily shadowed faces reduce animation quality noticeably.
Keep Audio Under 28 Seconds
Output length is frame-bounded at 25 fps up to roughly 28 seconds. Trim your audio before uploading rather than cutting it after, so the full clip is animated rather than truncated mid-sentence in the final MP4.
Pick 720p for Final Deliverables
Use 480p during early drafts to review lip sync and motion, then switch to 720p for your final export. This saves generation credits while still delivering a crisp video suitable for social platforms and presentation slides.
Use Clean, Dry Audio
Expressive motion is driven entirely by the audio signal. Background noise, heavy reverb, or overlapping sounds can confuse the motion model and produce erratic head movement. A close-mic recording with minimal room echo yields the most natural results.
When to choose this app
Choose Infini Talk when your priority is nuanced facial expressiveness from a single still image with an audio clip you already have recorded. Compared to SadTalker, Infini Talk offers higher resolution output at 720p with more natural head dynamics. Compared to Sync-3 Lipsync, it requires no source video, making it the right tool when you have only a photograph to start from.
Frequently asked questions
What image formats work best as input for Infini Talk?
A high-resolution JPEG or PNG portrait with a clearly visible, front-facing face works best. Images with busy backgrounds, strong side lighting, or significant motion blur can reduce the accuracy of the animated facial motion that Infini Talk generates from the audio signal.
Can I use an illustration or cartoon portrait instead of a real photograph?
Yes. Infini Talk works with illustrated or stylized portraits as well as photographic ones. The model derives motion from facial landmark regions, so as long as the illustration has recognizable eyes, nose, and mouth in a front-facing orientation, animation quality is generally good.
How do I control how long the output video is?
Output length is determined by your audio clip length, bounded by the maximum of roughly 28 seconds at 25 fps. Upload a shorter audio clip to get a shorter video. The model does not loop or pad audio, so the video ends when the audio ends.
What is the difference between 480p and 720p output for this app?
Both resolutions use the same animation model, so facial motion quality is identical. The difference is pixel density in the final MP4. Use 480p for quick draft reviews and 720p when producing a video intended for public sharing, presentations, or any context where visual clarity matters.
Does the background in my photo move or change during the animation?
Infini Talk focuses motion on the face and head region derived from your input image. The background remains largely static, which works well for clean portrait shots. If your photo has a complex or distracting background, consider cropping to a tighter framing before uploading.
Can I animate the same photo with multiple different audio clips?
Yes, and this is one of the most practical workflows in Infini Talk. You can reuse a single brand photo or character portrait with different audio recordings to produce multiple distinct talking avatar videos, such as different languages, topics, or speakers, each generated as a separate MP4.
Which AI model powers this app?
This app runs on Infini Talk, 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.
