Sync Lipsync 2 Pro on AI Compare Hub

Sync Lipsync 2 Pro is Sync Labs' studio-grade AI video lipsync model — delivering broadcast-quality mouth re-animation that matches a new audio track with cinema-grade fidelity.

What you can create

• Broadcast-grade voiceover replacement

  Replace the audio of broadcast or marketing footage with studio-quality lipsync output. Sync Lipsync 2 Pro preserves identity, skin texture, and lighting consistency for client-ready deliverables.

• High-fidelity multilingual dubbing

  Produce premium localised versions of brand films, product launches, and corporate content. Sync Lipsync 2 Pro generates mouth shapes that hold up under close-up shots and high-resolution playback.

• Film and episodic content updates

  Re-sync dialogue in narrative video for re-cuts, ADR-style updates, or alternative line readings. Sync Lipsync 2 Pro delivers the visual quality required for theatrical and streaming deliverables.

• Premium animated character dialogue

  Re-animate stylised and cinematic characters to revised audio without rebuilding the original animation. Sync Lipsync 2 Pro maintains character identity and motion at production resolution.

Why creators choose Sync Lipsync 2 Pro

• Studio-grade visual fidelity

  Sync Lipsync 2 Pro is tuned for the highest visual quality in the Sync Labs lineup. Mouth shapes are sharper, skin and texture detail are better preserved, and the result holds up to broadcast and theatrical resolution playback.

• Stronger identity preservation

  Faces remain recognisable across the re-animated mouth region, with consistent skin tone, beard / makeup detail, and lighting that match the original footage. Sync Lipsync 2 Pro avoids the "uncanny valley" softness common in lower-tier lipsync.

• Five sync modes plus expressiveness control

  The Pro model shares the full Sync Labs control surface — five sync modes (loop, bounce, cut_off, silence, remap), a temperature slider for expressiveness, and active-speaker detection for multi-person footage.

• Active-speaker detection for multi-person scenes

  Process panels, interviews, and group scenes with automatic active-speaker detection. Sync Lipsync 2 Pro identifies who is speaking and re-animates only that person's mouth, preserving the rest of the frame untouched.

How to generate your first studio-grade lipsync

1. Upload your source video. Provide an MP4 of the speaker whose mouth should be re-animated. Higher-resolution footage with even lighting produces the best Pro-tier output.
2. Upload your replacement audio. Add the WAV file containing the new voiceover, ADR line, or dubbed track that should drive the lip movement.
3. Configure and generate. Pick a sync_mode, set the expressiveness temperature, enable active-speaker detection if needed, and run Sync Lipsync 2 Pro on AI Compare Hub.

Common questions

What is Sync Lipsync 2 Pro?

Sync Lipsync 2 Pro is the studio-grade tier of Sync Labs' generative AI video lipsync model, available via the Replicate API. It re-animates mouth movements in any source video to match a new audio track, with significantly higher visual fidelity, sharper mouth detail, and stronger identity preservation than the standard Sync Lipsync 2 — built for broadcast, film, and high-end marketing work.

How is Sync Lipsync 2 Pro different from Sync Lipsync 2?

Sync Lipsync 2 Pro uses a higher-fidelity generation pipeline that produces sharper mouth shapes, better skin/texture preservation, and more consistent lighting compared to the standard Sync Lipsync 2. Both models share the same input parameters (sync_mode, temperature, active_speaker). Sync Lipsync 2 Pro is recommended when output will be viewed at high resolution or in close-up, and when broadcast or theatrical-grade quality is required.

What sync modes does Sync Lipsync 2 Pro support?

Sync Lipsync 2 Pro supports the same five sync modes as the standard tier: loop (default — repeats audio to match video length), bounce (plays audio forward then backward), cut_off (truncates the longer input), silence (pads the shorter input with silence), and remap (stretches one input to match the other).
