AI lip sync studio
AI Lip Sync Generator for Images and Videos
Match a portrait or existing video to your own voice track. Choose Kling AI Avatar for a talking portrait or Volcengine for video-to-video lip sync, review the exact credit estimate, and generate in one workspace.
01
Bring your own voice track
Upload recorded dialogue, narration, or a finished voiceover in common audio formats. SkyVid reads the media duration on the server and shows the billable seconds before you submit.
02
Choose the right source workflow
Start from one portrait with Kling AI Avatar Standard, or preserve the motion and framing of an existing clip with Volcengine Video-to-Video Lip Sync. The form changes to match the selected model.
03
Control timing for source video
Volcengine Lite can align audio, loop a shorter source clip, alternate the loop direction, and start from a chosen point. Basic mode adds scene detection for more involved footage.
04
Use speech in any language your audio carries
The lip sync workflow follows the uploaded audio rather than generating speech. That makes it practical for localized voiceovers without promising a built-in voice catalog or an unverified language count.
Where AI lip sync fits
Use short, clearly recorded audio and a visible face for the most dependable first result.
Product marketing
Turn approved voiceovers into compact presenter clips and product explainers.
Training and education
Update narration while keeping a familiar presenter or source clip.
Creator content
Prototype character dialogue, social hooks, and short performance clips.
Localization
Pair translated recordings with portrait or video material for regional variants.

SkyVid supports Kling AI Avatar Standard for portrait-image input and Volcengine Video-to-Video Lip Sync for source-video input.

Yes. Select Volcengine and upload an MP4 or MOV source video plus audio. SkyVid currently limits each source video to 100 MB and 300 seconds.

No. The current lip sync models require an uploaded audio file. Text-to-speech and voice generation are not included in the displayed lip sync price.

Use a clearly visible face, steady framing, even lighting, and clean speech. Short test clips are useful before processing a longer Volcengine source video.
