Brand Promo Video Generator

Read the portable workflow. Use supplied brand assets, source links, and existing session decisions. No proprietary tool allowlist or canvas is required. A completed promo requires real generation/editing capability; otherwise deliver an explicitly incomplete production package with finished prompts and a concrete generation handoff.

Establish facts and assets

Inspect product images, UI screenshots, logo exports, typography, colors, and campaign material. Resolve duration, ratio, audience, campaign focus, exact claims, CTA, copy language, narration, and required deliverable from context. Ask for missing identity-bearing assets when they are essential; do not fabricate logos, product UI, screenshots, results, or performance claims.

Build a compact truth sheet from user-supplied originals and official sources. Record asset ID, role, local path, source URL/note, and verification status. Do not confuse a retrieved search thumbnail with an original brand asset. Distinguish verified facts from clearly labeled concept copy. Preserve the requested language; chat language alone does not justify translating supplied campaign text.

Design a product-specific story

Choose a spine that exposes real cause and effect:

• Software: user intent → actual interaction → useful output → evidence → CTA.
• Physical product: reveal → interaction → mechanism/detail → use → benefit → CTA.
• Service: situation → process → evidence → outcome → promise.
• Image-led brand: authentic imagery → repeated visual motif → emotional payoff.

Plan time/frame ranges, asset IDs, one main action, product evidence, exact copy, readable hold, color state, camera, transition, and rhythm. Use the actual output fps for frame timing. Five to eight major beats can fit a 15-second promo, but readability takes priority over a fixed beat count.

Let product edges, UI movement, light, cursor paths, or matched geometry motivate transitions. Use a few energy peaks and deliberate settling moments. Preserve logo clear space and readable screenshots. Avoid invented HUDs or metrics that look like product proof. Summarize the truth sheet and plan before rendering; continue under existing authorization unless the user requested approval at that stage.

Produce and inspect

Use authentic still/UI plates for exact content. Generated material can supply conceptual scenes, atmosphere, and transition geometry with clear provenance. Compile actual H3 references and shots using the appropriate bundled guide. Check backend resolution, duration, and audio support before calling it.

Use native instrumental/SFX direction when appropriate; do not generate a second score automatically. Separate narration or music is useful when requested for control or remixing. Preserve original SFX during assembly when they matter, and duck music under speech. Do not add subtitles unless requested.

Check claims and exact product names against sources, inspect logo geometry and copy, verify real UI states, and review transitions, aspect ratio, duration, audio, and decoding. For wrong identity-bearing content, use the correct supplied/source asset rather than polishing an imitation. Deliver the video, prompts/timeline, asset manifest, and any remaining factual or visual limitations.
