Measures how realistic and coherent motion is across frames — including natural movement, fluid transitions, and absence of warping, jitter, or ghosting artifacts. What each rating means here Strong Smooth, physically plausible motion with natural acceleration, fluid transitions, and minimal warping or temporal artifacts. Moderate Motion is mostly convincing but shows subtle jitter, unnatural acceleration, or occasional warping on complex or fast-moving scenes. Weak Obvious motion artifacts — jitter, warping, or frame-to-frame inconsistency undermine the realism of the clip.

Measures whether subjects, backgrounds, and fine details remain stable frame-to-frame — avoiding identity drift, morphing, or unexpected visual changes mid-clip. What each rating means here Strong Subjects and backgrounds remain stable throughout the clip — no identity drift, face morphing, or background flicker across frames. Moderate Generally stable but shows gradual drift or minor flickering on fine details, particularly in longer or complex clips. Weak Noticeable identity drift or background inconsistency; subjects may morph or lose visual detail mid-clip.

Measures how closely the generated clip matches the text description — including subject, action, style, composition, and camera direction instructions. What each rating means here Strong Closely follows the text description — correct subject, action, style, and camera direction with high fidelity throughout the clip. Moderate Captures the main subject and action but may miss stylistic details, camera instructions, or specific secondary elements. Weak Captures the general mood or subject but frequently ignores specific actions, style direction, or compositional instructions. Variable Adherence varies with prompt complexity — reliable for simple descriptions, inconsistent for compound or highly specific instructions.

Measures whether the model generates synchronised audio — ambient sound, foley, speech, or music — natively alongside the video rather than requiring a separate pipeline. What each rating means here Strong Generates synchronised, contextually appropriate audio — ambient sound, foley, or music — that matches the on-screen action naturally. Moderate Produces audio alongside video but synchronisation or contextual fit is imperfect; works best for simple scenes. Weak No native audio support, or generated audio is clearly mismatched with the visual content.

Measures the highest output resolution the model produces natively before quality degrades, independent of any post-processing upscaling. What each rating means here Strong Produces large, high-quality native output at 1080p or above across multiple aspect ratios before any upscaling is needed. Moderate Solid at standard sizes; native quality degrades at higher resolutions — upscaling is needed for HD or large-format delivery. Weak Limited to lower native resolutions; quality degrades quickly as output dimensions increase. Variable Usable resolution depends on the chosen endpoint, plan, or quality setting — check provider specifications for your target output size.

Measures generation latency relative to clip length. Slow inference raises cost per second of output and limits interactive or real-time applications. What each rating means here Strong Fast generation — produces clips quickly relative to their length, keeping cost-per-second of output low. Moderate Typical generation time; fine for batch or async workflows but noticeable latency in interactive or real-time use. Weak Slow to generate, raising both latency and cost-per-second of output significantly relative to clip length. Variable Speed scales with clip length and resolution — fast for short clips at standard quality, much slower at maximum length or resolution.

Measures the maximum clip length achievable in a single generation pass while maintaining consistent quality — longer ceilings reduce stitching requirements. What each rating means here Strong Generates clips of 10 seconds or longer in a single pass with consistent quality throughout. Moderate Manages 5–10 seconds reliably; quality or coherence may degrade toward the end of longer clips. Weak Limited to short clips (under 5 seconds); stitching multiple clips is required for longer sequences. Variable Maximum duration depends on the chosen resolution or quality setting — higher settings reduce the achievable clip length.

Capability ratings are an expert synthesis across benchmarks, community evaluations, and provider documentation. “—” means no profile data for that dimension.
