OmniHuman vs Kling AI: Comparison Across 5 Key Fields

To determine which one performed better, we subjected both OmniHuman and Kling AI to five key performance tests. The comparison highlights what each model excels at and how their unique features can assist with various video-making demands.

Test 1: Lip-sync accuracy (Ability to match speech with realistic mouth movements)

Test prompt: Make a movie of two AI avatars sitting across from each other in a busy café and having a pleasant discussion. The avatars should be able to lip-sync naturally to different speech tones, with mouth motions that match the intonation and tempo of the speech. To see how effectively speech matches body language and emotional indicators, include small details such as sipping coffee, smiling, adjusting your posture, and maintaining eye contact.

OmniHuman AI is great at lip-syncing in the café scenario. It makes mouth motions that perfectly match changes in tone, tempo, and emphasis in conversation. The synchronization feels effortless, and the discussion flows naturally thanks to natural expressions like smiles, raised eyebrows, and subtle changes in posture. Kling AI also demonstrates a strong connection between audio and visual output, with smooth transitions and expressive cues. However, its emotional depth in micro-expressions seems a little less potent than OmniHuman's. Overall, OmniHuman stands out because it facilitates interactions that feel more like genuine conversations than scripted content. Kling AI, on the other hand, remains trustworthy in maintaining consistency in accuracy across various speech inputs.

Test 2: Visual realism (Ability to create lifelike digital humans)

Test prompt: Make a movie of one AI avatar giving a short speech on stage in front of an audience while bright lights shine on them. The lighting should be just proper so that the scenario looks like real life, with realistic skin texture, facial micro-expressions, and natural clothes folds. Add moving camera pans and zooms to see if the avatar's movements and appearance stay realistic in both close-ups and wide shots.

OmniHuman AI gives very realistic visuals when used in cinematic stage circumstances. Skin textures, subtle lighting reflections, and natural clothing folds all appear well in both close-up shots and wide pans. It can capture subtle facial movements, such as eye squints and lip tension, throughout speech, which makes it feel like a real person is present. Kling AI lip-sync also does a great job, with fluid renderings and body proportions that remain consistent, even when the light is shining on them. Kling's visuals are still good, but OmniHuman adds depth and nuance to the experience, ensuring that the avatar not only looks realistic but also acts authentically in movie-like situations.

Test 3: Multimodal adaptability (Handling different inputs: image, audio, motion)

Test prompt: Make a video of an AI avatar jogging across a park and giving a speech to get people moving. The input consists of a picture of a person, a voice recording, and an instruction to act. The avatar should move its lips in sync with the narration, jog realistically, and make expressive movements, such as hand sweeps or head turns. To assess how well speech, expressions, and motion work together, you should add environmental signals, such as trees swaying, joggers walking by, and sunlight moving.

In the scene where OmniHuman-1 jogs across the park, it demonstrates great multimodal integration by seamlessly blending facial expressions, speech, and motion in a completely natural way. The avatar's lips move precisely in time with the narration, the jogging mechanics and head turns all fit seamlessly into the setting. The landscape feels lifelike because of small interactions with waving trees and ambient lighting. Kling AI model also excels at handling multimodal inputs. It syncs voice and movement with reasonable precision, but its motions and interactions with the surroundings seem a little stiffer. In general, OmniHuman performs smoothly and realistically, demonstrating its ability to work with a wide range of input types. Kling AI, on the other hand, remains a powerful and efficient choice for generating rapid, cohesive outputs.

Test 4: Movements and expression fidelity (Ability to replicate human expressions)

Test prompt: Make a film of an AI avatar giving a dramatic speech in a theater rehearsal area. The script should evoke different emotions, starting with serenity, then progressing to rage, and finally sadness. The avatar should convey changes in emotional tone through hand movements, posture adjustments, and facial expressions. To assess the accuracy of expression consistency and natural body language during emotional changes, include both side and front views.

OmniHuman AI excels at conveying subtle movements and emotional depth in the theater monologue scenario. It smoothly captures the changes from calm to angry to sorrowful. The avatar's changes in posture, and little facial emotions are all perfectly in rhythm with the changing emotional tone, making the performance feel very genuine. There is consistent expressiveness and precise body language throughout, as evident from various perspectives, including side profiles and frontal shots. Kling AI displays clear and accurate facial expressions and lip-syncs that are reliable, maintaining the emotional arc, although its movement changes are slightly less dramatic. ByteDance OmniHuman excels at creating a totally immersive, emotionally rich performance, whereas Kling AI offers a polished and reliable option for expressive content.

Test 5: Customization and voice integration (Ability to handle voices and styles)

Test prompt: Make a movie of two AI avatars at a birthday party talking, laughing, and carrying drinks. Each avatar has its own vocal style: one is serious and professional, and the other is light and happy. They all have natural lip-sync, movements, and expressions. Also, add some party sounds, like background music, clinking glasses, and moving confetti, to see how effectively the models mix voice, style, and setting.

In the party scenario, OmniHuman AI excels at adapting each avatar's vocal style to match the party's mood. This makes interactions seem more realistic, with facial expressions, fluid movements, and posture changes that enhance the lively environment. Even when voice tones differ, lip-sync accuracy remains consistent, and elements like music and confetti blend in seamlessly. Kling AI also works well, with precise voice alignment and accurate lip-sync, but its repertoire of movements is a little smaller, which makes the interaction feel less lively. Overall, OmniHuman excels at creating highly realistic avatars based on real people, whereas Kling AI lip sync provides a reliable and efficient method for generating interesting outputs.
