Prompt tips

• Any-language prompts up to 5000 chars (2500 Chinese) — excess is silently truncated, so front-load subject → action → scene → camera → style.
• 3-15 seconds per second of billing; 720p or 1080p; ratios 16:9 / 9:16 / 1:1 / 4:3 / 3:4. Pick the shortest duration that serves the shot.
• ref2v is one of the few true REFERENCE modes on the roster: wired refs keep identity across the clip — bind each reference explicitly in the prompt.
• No published vendor style guide — the platform's standard structure applies; keep one camera move per shot and quantify motion physically.
