Magic Hour lip sync: workflow, pricing & troubleshooting


Quick answer
Magic Hour Lip Sync matches a visible face in an existing video to a supplied audio track. Use it to replace a line or create a dubbed version without recording the picture again. Start with a short sample, approve the speech and facial movement, then generate the full version. For a still portrait, use Talking Photo instead.
Try lip sync on a short clip
Upload a short permitted video and approved audio, then review timing, identity, edges, and the complete result.
Try Lip SyncMagic Hour publishes this guide about its own Lip Sync product. Treat it as product documentation rather than an independent review; verify the current workflow, limits, pricing, and output on a short permitted sample before committing a full project.
When Magic Hour Lip Sync fits the job
Your task | Starting workflow |
|---|---|
Replace narration spoken by an on-screen person | Lip Sync: video plus the approved new audio |
Make a portrait deliver a short message | Talking Photo: image plus audio |
Create speech from a written script | Voice Generator, then review the audio before syncing |
Create a scene without source footage | Generate the picture first; lip sync alone does not create an entire scene |
Translate an existing video | Approve the translation and voice before synchronizing the lips |
A practical dialogue-replacement workflow
Imagine an onboarding video says “Click the green button,” but the interface now uses a blue button. Replace the spoken instruction with “Click the blue button” and supply the new audio to Lip Sync. Review the screen recording too: synchronized speech will not update the button shown in the picture.
- Trim a continuous shot containing the visible speaker and the line to replace.
- Record or generate the new line at a pace that fits the scene.
- Listen to the audio by itself and approve every word.
- Upload the video and audio to Magic Hour Lip Sync.
- Watch the generated result through the start, pause, and end of the sentence.
- Put the approved clip back into the edit and update any captions or on-screen instructions.

What is free, and when do you need a paid plan?
The current Lip Sync product page offers three guest generations per day without signup, with a ten-second maximum. Free video results may include a watermark. Account credits, saved projects, rewards, higher limits, watermark-free output and commercial-use eligibility depend on the current account and plan.
Paid plans currently add credits, higher export limits, API access, commercial use and watermark-free exports under the applicable terms. Prices are localized and can change, so use the current pricing page for the visitor's region and billing period instead of relying on a copied dollar amount.
Try the sample before choosing a plan. Pay for the duration, mode, and export your project needs after the result meets your requirements.
What to fix when the result looks wrong
Symptom | First thing to check |
|---|---|
Audio is consistently early or late | Input start times and the selected segment; correct a simple timing offset in the edit |
Mouth is unclear or distorted | Face angle, blur, lighting, and objects covering the mouth |
Lip movement continues through pauses | Silence and background sound in the supplied audio; compare a cleaner recording |
The wrong person appears to speak | Multiple visible faces or overlapping speakers; test a single-speaker shot |
The line sounds rushed or ends abruptly | Audio length against the available scene; rewrite or record a shorter line |
The face changes during a turn | A different source angle or a less obstructed shot |
Do not keep regenerating the same unsuitable inputs indefinitely. A reshoot or conventional edit may be the better way to finish a difficult scene.
Using Lip Sync through the API
The current Lip Sync API tool guide documents per-rendered-frame charging: Lite and Standard use one credit per rendered frame and Pro uses two. A ten-second clip capped at 30 FPS is about 300 credits at the one-credit rate. The completed job's credits_charged field is the exact cost; the initial value can be an estimate based on the eventual rendered FPS.
Use the API reference for upload fields, segment selection, and frame-rate settings. Keep API billing calculations separate from the free guest website offer.
Before publishing a dubbed or edited video
Check the message, face, audio, captions, and any visible demonstration together. For localization, have a fluent speaker review the translation. Make sure your use of the person's likeness, voice, and footage is authorized; a paid plan does not supply those permissions for someone else's media.
If you are still choosing a platform, use the lip sync comparison. If your next step is simply trying a recording, open Lip Sync with one short clip and its approved audio.
