Help me plan one product video using the brief below.

PRODUCT: [name and what it does]
AUDIENCE AND NEED: [one buyer and one problem]
VERIFIED FACTS: [approved claims + source for each]
DO NOT CLAIM: [unproven benefits, discounts or testimonials]
ASSETS AND RIGHTS: [photos, clips, logo, dimensions, permission]
CHANNEL: [product page, ad, Reel, Short, etc.]
LENGTH / ASPECT RATIO: [seconds] / [9:16, 16:9 or 1:1]
LANGUAGE AND TONE: [language, reading level, brand voice]
CTA: [one next step + exact URL or wording]
BUDGET: [approved paid services and maximum extra spend]

First flag missing facts, assets, permissions or capabilities.
Do not invent product features or imply you inspected an absent file.
Then deliver:
1. A short production brief and a claim-to-source list.
2. A timed script: hook → product evidence → CTA.
3. A shot list with start/end, asset, action and on-screen text.
4. Caption text; only provide timed SRT when the cut is fixed.
5. A review checklist and a list of missing or generated assets.

Use real product visuals where accuracy matters. Do not alter labels,
shape, colors or included accessories. Mark proposed generated visuals.
Ask before spending beyond the approved budget.
If you cannot render or export a video, deliver the production packet
and say clearly that no video has been created.
