What to compare visually
For a fair A/B test, use the same scene and, where both modes allow it, the same first frame. Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization.
What to inspect with Kling AI Avatar
A speaking or singing portrait from one photo and a finished audio track.
- One photo and one audio file are required.
- Standard outputs 720p; Pro outputs 1080p. Duration follows the audio, up to 300 seconds.
- Typed text cannot replace the audio file.
- A strong profile, hidden face or multiple voices can weaken lip synchronization.
What to inspect with OmniHuman 2.0
A talking avatar from one photo and your audio recording: 720p video as long as the audio.
- One photo (up to 30 MB, each side 300 to 6000 pixels, aspect ratio 0.4 to 2.5) and one MP3 or WAV audio file up to 15 MB.
- Audio from 4 seconds to 5 minutes. On the site and in Canvas other formats are converted to MP3; Telegram accepts only MP3 and WAV.
- Exactly one photo and one audio file are accepted; audio shorter than 4 seconds or longer than 5 minutes is rejected before billing.
- Resolution, frame format and duration cannot be chosen; a long track costs proportionally more.
How to run a fair comparison
- Fix the scene, the first frame (if both models accept one), the duration and the resolution.
- Judge motion, not stills: faces, hands and objects should hold across the whole clip and at cuts.
- If sound matters, listen to it separately: dialogue, effects and lip sync differ between models.
- Price a finished clip, not a second: the per-second rate times your real duration, rounded up once.
