Overview

OmniHuman v1.5 Talking Human Video turns a portrait image and short audio file into a lip-synced talking-human video with optional prompt guidance and turbo mode. Use it for founder clips, spokesperson drafts, product explainers, and social videos that need more direction than the base OmniHuman AI Tool.

Use cases

  • Create a talking-human video from a founder portrait and final voiceover audio.
  • Add prompt guidance when the scene, style, delivery, or visual context matters.
  • Use turbo mode for faster review drafts when a slight quality tradeoff is acceptable.
  • Compare v1.5 against the base OmniHuman AI Tool before choosing the final talking-video direction.

Input tips

  • Provide public image_url and audio_url values that can be fetched without login.
  • Use a portrait image with a clear face and a clean speech audio file.
  • Keep the audio file under 30 seconds.
  • Add prompt guidance only when it helps shape the scene, style, or delivery.
  • Leave turbo_mode off for the default quality path; turn it on when faster generation matters.
  • Prepare the voice track before running; the AI Tool lip-syncs to the supplied audio.

Expected output

The AI Tool returns one generated talking-human video with a downloadable URL, optional content type, file name, file size, output duration, and cost metadata. The shared avatar-video view renders the video, formatted duration, and model label.

Caveats

  • Private, expired, or blocked image/audio URLs will fail.
  • Poor audio, cropped portraits, low-quality faces, or mismatched speech can reduce lip-sync quality.
  • Generated facial motion should be reviewed for realism, consent, brand fit, and policy fit.
  • Turbo mode can be faster but may trade off some visual quality.
  • This AI Tool uses premade audio; it does not create the voice track, script, transcript, or captions.
