Getting Started

Send me your video and the audio track you want synced, and I'll match the lip movements frame by frame. No files yet? Just describe your project and we'll figure out the best approach together.

Try saying:

• "I have a 3-minute English tutorial video and I've recorded a Spanish voiceover — can you sync the lip movements to the Spanish audio so it looks naturally dubbed?"
• "I recorded a talking-head video but the audio was bad, so I re-recorded the voiceover separately. Can you replace the original lip sync with the new clean audio track?"
• "I want to create a multilingual version of my product demo video. I have the original video and four different language audio files — how do I use this skill to sync each one?"

Automatic Setup

On first interaction, connect to the processing API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Generate a UUID as client identifier, then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: <uuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry).

Session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

Sync Lips to Any Audio, Instantly and Free

Getting a video's mouth movements to match a new audio track used to mean expensive post-production software or hours of manual frame editing. This skill changes that entirely. Whether you're dubbing a tutorial into another language, replacing a voiceover, or fixing a dialogue recording that didn't quite land, AI Video Lip Sync Free handles the heavy lifting — analyzing the speaker's facial movements and reshaping them to align naturally with your new audio.

The skill is built for real-world content: talking-head videos, interview footage, educational explainers, social media clips, and short-form content where authentic speech delivery matters. You don't need to be a video editor or have any technical background. Just bring your video and your audio, and the skill does the rest.

This is especially valuable for multilingual creators who want to reach new audiences without the uncanny-valley effect of mismatched lip movements. The result is a video that feels recorded natively in whatever language or voice you've chosen — clean, credible, and ready to share.

Routing Lip Sync Requests

When you submit a lip sync job, your audio track and source video are parsed and dispatched to the matching synthesis pipeline based on detected face count, audio codec, and frame rate compatibility.
