What AI lip sync does in a music video
AI lip sync makes a face sing your song. You add a track with vocals, choose who sings, and in a few chosen shots the mouth follows your actual words instead of moving at random. In Melodious this applies to up to four chorus close-ups per video. Everything around them, the wide shots, the cutaways and the verses, is original AI footage planned from your song's structure.
That is narrower than the phrase suggests, and it is the honest version. Lip sync is the most expensive and the riskiest kind of shot a music video can contain, so the flow around it is built to limit your exposure: few shots, close-ups only, a test before you commit, and no charge for a shot that cannot be lip-synced.
How it works, step by step
- Upload a song with vocals. Melodious analyses the track once, finding its sections, tempo and whether there is a vocal. For an instrumental track the lip sync option is never shown.
- Switch lip sync on in the brief. It is off until you turn it on, and it lives in the brief, not in the prompt box.
- Choose who sings. The subject of your idea (a dog in a tree, a robot), you with a photo you add, or someone else, which can be a saved character or a short description of a singer.
- Review the board. The director marks up to four chorus shots as singing shots, written as front-facing close-ups, each with a Sings badge and the lyric line. You can move a mark to another shot or turn it off.
- Test one line. Render a single singing shot alone, check the singer, and decide before you pay for the rest.
- Render. Singing shots go through OmniHuman, a lip-sync model that animates a face from a picture and the audio. All other shots go through the normal video model. You download one finished video.
What it costs
A singing shot costs 2.2 times a normal shot's render price, because the lip-sync model is a separate and more expensive one. At 720p, an 8-second normal shot is 148 credits and a singing shot is 324. A 4-second normal shot is 74 and a singing shot is 162. Drawing the keyframes costs the same as always, and the quote you see before rendering already includes the multiplier.
Singing shots are made at 1080p at most, because that is the most the lip-sync model produces. On a 4K render they are charged at the 1080p rate, not the 4K rate, and the 4K option says so. Plans from $19/month · cancel anytime. The brief is free, and new accounts get a free 30-second storyboard — you subscribe when you render the video. Four short singing shots add up to a large share of a small plan's monthly credits, so the realistic use is a few well-chosen lines, which is also what makes a video feel like a performance. The full numbers are on the pricing page.
What it does not do
- It does not lip-sync the whole video. Up to four chorus close-ups, not a full performance.
- It does not lip-sync a face that cannot be seen. If the mouth is not visible in the keyframe, the shot is rendered as a normal shot at the normal price.
- It does not make verses sing by default. Dense verses are where mouth shapes are most likely to drift from the words, so the default spends the budget on the lines viewers remember.
- It does not do talking-head avatars, dubbing or translating video into other languages. It is built for songs.
- It does not write the song. Start from a finished track, from Suno or anywhere else.
How it compares with other kinds of lip sync tool
Most search results for an AI lip sync tool fall into three groups, and they are different jobs. We describe the categories rather than rank products, because features change quickly and we have not re-tested every tool for this page.
Talking-avatar and dubbing tools take a face and a voice and make a presenter or a translated video. They are built for speech and explainers. They are a good fit for a tutorial and a poor fit for a directed music video.
Singing-photo tools take one picture and one song and animate that picture for the length of the track. They are quick and fun, and the result is one face and one background for three minutes.
Lip sync inside a directed video is what Melodious does: a storyboard of different scenes, the same character throughout, and singing close-ups placed where the chorus lands. You get variety and a performance moment, and the limit is the four-shot cap. If what you need is one face singing a whole song, a singing-photo tool is the right one. If you want a music video that includes singing, this is.
Tips for lip sync that looks right
Our first model test was one five-second chorus line on a person, a stylised character and a dog. The stylised character gave the clearest mouth shapes, and the dog held steady and faced the camera in quality mode. That is three clips and not a benchmark, so treat it as a hint. Four habits help: choose a clear, frontal close-up; test a short, punchy line rather than a dense one; keep to one singer so the four shots stay consistent; and save a character first if the singer needs to look the same across the whole video.
Before you start, a genre check helps the video match the song, and the music genre finder and the BPM finder are free to use. If you are still writing, the AI lyrics generator drafts lyrics, and the Suno prompt generator helps you make the song. The whole process is covered on the AI music video generator page, and there is a longer guide in the blog on AI lip sync for music videos.
Frequently asked questions
What is an AI lip sync tool for songs?
It animates a face so the mouth follows a vocal. In Melodious you add a song with vocals, switch lip sync on in the brief, choose who sings, and the director marks up to four chorus close-ups as singing shots. In those shots the character sings your actual lyrics on camera. The rest of the video is original AI footage cut to your song.
Is the whole video lip-synced?
No. Lip sync is limited to up to four chorus close-ups per video. The wide shots and cutaways around them are not lip-synced, so this is not a full performance video of a singer. We say this plainly because a lot of tools in this category imply otherwise.
Can an animal or a cartoon character sing?
Yes. Any subject can be the singer, including animals and stylised characters. The shot only becomes a singing shot if the face and mouth are clearly visible in its keyframe. If they are not, the shot is rendered as a normal shot at the normal price, and the storyboard tells you to redraw it as a close-up if you want it to sing.
How much does lip sync cost?
A singing shot costs 2.2 times a normal shot's render price. At 720p an 8-second singing shot is 324 credits against 148 for a normal one, and a 4-second one is 162 against 74. The price you see before rendering already includes the multiplier. Singing shots are made at 1080p at most, so a 4K render charges them at the 1080p rate.
Can I try it before I pay for the whole video?
Yes. Test this line renders a single singing shot on its own, so you can check the singer before paying for the full video. It is priced like any singing shot and takes about three minutes. The clip is reused in the full render rather than charged twice, as long as the test really was lip-synced.
Which model does the lip sync?
Singing shots use OmniHuman, a model from ByteDance that animates a face from an image and an audio clip. We tested several options on a person, a stylised character and a dog, and OmniHuman in quality mode gave the best result overall. That was three clips on one song, not a benchmark, so use Test this line as the real answer for your own track.
Is lip sync free?
Not the render. The brief and a first 30-second storyboard are free for new accounts, with fair-use limits, so you can see the plan and the singing shots marked on the board. Rendering takes a paid plan, and you see the full cost, with the lip-sync multiplier included, before anything is spent.
Hear your chorus sung back to you
Attach a track and describe what you want in one message. An AI director storyboards it scene by scene, with the same character in every shot. Your first project's keyframes are free, so you see the whole storyboard before deciding to render.
