VideoFX
VideoFX lip sync AI analyzes audio waveforms at phoneme granularity to extract precise timing for every consonant, vowel, and breath. The engine maps phonetic markers to facial muscle groups, generating realistic mouth movements that match each syllable with sub-frame accuracy. Whether you need multilingual video dubbing for global distribution, talking avatar creation from a single portrait, or dialogue replacement in post-production, this lip sync AI preserves natural facial expressions while delivering broadcast-quality results. Multi-speaker detection identifies individual characters in complex scenes for independent voice-to-face mapping.
Lip sync runs inside the VideoFX Studio alongside text-to-video and motion control — generate footage, dub it, and animate characters in one project timeline.
Drop any audio file onto a VideoFX Studio timeline and the lip sync engine maps each phoneme to the target face within the same project. Because the audio waveform is analyzed at consonant-and-vowel level, the resulting mouth shapes stay accurate across 40+ languages — and the synced clip feeds directly into motion control or color grading without re-exporting.
The engine isolates each consonant and vowel from the uploaded audio, then generates a per-frame mouth-shape map — accuracy measured at 98%+ on the LRS3 benchmark
Dedicated phonetic models cover English, Mandarin, Spanish, Arabic, Hindi, and 35+ additional languages; switch target language mid-project without leaving the Studio
Scrub through the synced timeline inside VideoFX to spot-check any frame before sending the clip to motion control or final render
Start from a text-to-video prompt or a single portrait, then apply lip sync to produce a talking digital human — all within one VideoFX project. The Studio composites head motion, blink cycles, and micro-expressions on top of the synced mouth layer, so the avatar is render-ready without external compositing tools.
Feed a single headshot into VideoFX and the engine generates 24 fps head motion with parallax depth — no mocap rig required
Blink rate, brow raises, and jaw tension are inferred from speech prosody so the avatar reacts to emphasis and pauses naturally
Set gaze anchor points on the Studio canvas; the avatar tracks them while speaking, producing presenter-grade eye contact
Queue multiple language tracks in the VideoFX batch dubbing pipeline: upload one source video, attach translated audio files for each market, and the Studio re-syncs every version in parallel. Output lands in your project folder tagged by locale, ready for distribution — no per-language re-export needed.
Batch-queue EN→ES, EN→ZH, EN→AR, and 37+ other pairs; the pipeline re-syncs each version without manual intervention
The Studio tracks up to 8 on-screen faces per scene, assigns each a separate audio channel, and syncs them independently
Clone the original speaker's timbre into the target language so dubbed output retains vocal identity while lip timing stays frame-locked
Professional-grade capabilities for video dubbing, voice synchronization, and digital human creation at scale.
From film dubbing to virtual presenters, voice-driven synchronization powers content localization across global media production.
Import raw footage from the VideoFX text-to-video module, attach translated dialogue tracks, and run the batch dubbing pipeline to produce 10+ localized cuts in a single session. The Studio keeps the actor's upper-face performance intact on a separate rendering layer while re-mapping mouth shapes to the target phoneme set — reducing post-house ADR budgets by up to 85%.
Generate a character with VideoFX text-to-video, then pipe it through lip sync and motion control to produce a fully animated digital spokesperson — portrait in, broadcast-ready avatar out. The Studio composites gaze anchors, blink cycles, and head sway on top of the synced mouth layer so each presenter clip is render-complete without third-party compositing.
Upload an instructor-led course once, then batch-dub it into 40+ languages through the VideoFX pipeline. Each localized version keeps the instructor's on-camera presence and gesture timing intact because lip sync and motion control share the same project timeline — cutting per-market localization cost by up to 80% compared to re-shooting.
