Infinite Talk AI
— Infinite-Length
Talking Video Generator
Turn any image or video into long-form talking footage. Our sparse-frame pipeline edits the whole frame for accurate lip-sync, stable head & body motion, and consistent identity.
How it works
Three simple steps to create stunning talking videos
Choose Workflow
Pick image-to-video generator or video-to-video lip-sync based on your project. image-to-video generator
Upload Source & Audio
Add a video or single image plus your audio (voiceover, podcast, dialogue).
Supported formats: MP4 / JPG / PNG / WAV / MP3.
Highlights
Unlimited Duration
Generate long-form content without hard time limits—great for lectures, podcasts, and multi-chapter explainers.
Precision Lip-Sync
Phoneme-aware alignment keeps speech on-beat and visually convincing, frame after frame.
Stability at Scale
Reduced flicker and body distortions across long sequences; smooth posture and gesture continuity.
Identity Preservation
Keep the same face and style throughout the video—even across scene changes and long takes.
I2V & V2V Workflows
Use Image-to-Video (single photo → talking video) or Video-to-Video (re-animate source footage) in one place.
1080p Export
Get crisp, publication-ready results at 1080p with the same whole-frame stability and lip accuracy.
Under the Hood
Temporal Context
Overlapping context frames carry motion "momentum" across chunks, minimizing flicker and visible seams in long videos.
Soft Reference Control
Control strength adapts to context-to-reference similarity, preserving identity without making the avatar look stiff.
Sampling Strategy
Fine-grained keyframe placement balances control and motion alignment so lips, head, and body stay naturally in sync.
End-to-End Consistency
From lips to limbs, the pipeline ties facial nuance and body kinetics to your audio for coherent, whole-frame editing.

Performance note
1080p yields the highest visual clarity and lip detail. It also uses more compute; render time scales with duration and the number of speakers. For speed-sensitive drafts, start at 480p/720p, then export the final cut in 1080p.
