What "Good" Looks Like in AI Video

Motion Stability

Most AI video demos look great in the first second. The problems show up when motion stacks: hands drift or merge, faces lose identity during turns, and backgrounds "swim" while the subject moves. If a model stays stable during fast movement + camera motion, it's usually solid for most creator work.

Prompt Adherence

Prompt adherence isn't about poetic prompts. It's simple: if you ask for "a product shot with a slow push-in," do you actually get a slow push-in? If you ask for "two characters," do you get two characters the whole time? When adherence is weak, you spend credits re-rolling instead of creating.

Controls You'll Actually Use

For creators, the most useful controls are the boring ones: resolution and aspect ratio, a clear way to switch between text-to-video vs image-to-video, and a predictable place to adjust settings before generating. That's why platform workflow matters as much as model claims.

If you're reviewing models objectively, write down the controls you can confirm on day one:

• What resolutions are selectable?
• What aspect ratios are selectable?
• Is there a clear "mode switch" (text vs image input), or do you have to change workflows?
• Can you reuse a saved preset, or are you rebuilding settings every time?

These are small UX details, but they directly affect your daily workflow efficiency.

Seedance 1.5 Pro: Strengths and Limitations

What Seedance 1.5 Pro Does Well

• Native audio-visual sync with spatial sound: Generates video with synchronized audio in one pass, supporting multiple languages (Chinese, English, Japanese, Korean, Spanish, Indonesian) and dialect variants (Sichuan, Taiwan Mandarin, Cantonese, Shanghainese, etc.) with natural voicing, lip-sync accuracy, and spatial sound effects that coordinate with visuals.
• Intelligent narrative auto-completion: Automatically fills in narrative details based on prompt intent, maintaining cohesive storytelling across characters' emotions, expressions, and actions—ideal for short dramas, micro-dramas, and social media content.
• Clear resolution control: Offers 480p, 720p, and 1080p options with a Pro/Lite split for quality vs speed tradeoffs.
• Physics-accurate motion: Handles complex motion scenarios like hair dynamics, fluid behaviors, and material interactions with structural stability.
• Cinematic camera movements: Supports advanced techniques like long-take tracking, Hitchcock zoom, and seamless shot transitions for cinematic storytelling.
• Multi-shot generation: Creates cohesive narrative videos with multiple shots while maintaining subject consistency across transitions.

Where It Falls Short

• Shorter clip duration: Maxes out at 5–10 seconds, which limits full mini-stories or multi-beat scenes compared to Wan 2.6's 15-second maximum.
• Limited text rendering: Not optimized for generating clear, readable text within video frames (product labels, signage, etc.)—a key differentiator where Wan 2.6 excels.
• Motion stability improvement needed: While physics-accurate, the model's motion stability in highly dynamic scenes (fast action, rapid camera movements) still has room for improvement according to official evaluations.

Best for: Creators who prioritize cinematic camera control, multi-language/dialect voiceovers, and physics-accurate motion for short-form content (5–10 seconds), narrative storytelling, micro-dramas, short dramas, and professional film-style clips.

Wan 2.6: Strengths and Limitations

What Wan 2.6 Does Well

• Longer clip duration: Supports up to 15 seconds, giving you more room for complete story arcs and multi-beat scenes.
• Native audio-visual sync: Generates video with sound in one pass (auto-generate or custom audio input), eliminating the need for separate audio editing.
• Text rendering capability: Excels at rendering clear, readable text within video frames—ideal for product packaging, signage, and branded content.
• Multi-shot narrative: Maintains subject consistency across shot transitions with intelligent scheduling.
• Reference character/object generation: Allows you to use reference images for consistent characters or products across multiple clips.

Where It Falls Short

• Less emphasis on physics-accurate motion: Prioritizes audio-visual sync and multi-person dialogue stability over fine-grained motion physics—may not be ideal for complex action scenes or sports content.
• No explicit Pro/Lite split: Unlike Seedance's clear quality-vs-speed tradeoff options, Wan 2.6 doesn't offer a "fast mode" for rapid iteration.

Best for: Creators who need longer clips (up to 15 seconds), clear text rendering for branded content, and reference-based character consistency across multiple videos.
