Riffle two small card packets into one interleaved overlap

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Show the facing corners of two small card packets being released gradually so separate cards settle between cards from the other packet. Stop at the interleaved overlap before pushing the packets together. The shot should expose how the overlap forms, not simply reveal a shuffled deck.

Use a small number of plain flexible cards with readable separate edges. This untested handling plan excludes a bridge finish, dealing and randomness claims.

2. Authorized first frame

Prepare your own or authorized photograph or accurate drawing of two small packets on a plain mat. Show both hands already holding the outer portions, with thumbs restraining the raised facing corners. The lower outer edges remain supported by the mat.

Use an oblique close view that exposes the layered edges and the space where the packets will meet. Make the two packets distinguishable by plain back colors without text or suits. Leave a modest overlap zone in the center. Avoid a top-down view that hides whether a card passes above or below another card.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Start from my authorized image of two small plain card packets, held by the original hands with their facing corners gently bent upward. Lock the oblique camera and mat. Keep the outer lower edges supported. Relax the original thumbs gradually so the existing cards release in small successive groups from each packet and settle into the spaces between cards of the other packet. Keep every released card connected to its original visible body; card tips must not appear from empty space. Show a readable alternating interleave near the facing corners, without demanding a perfect one-for-one order. Preserve each packet color, card dimensions and the original hand identities. The cards flex and recover locally without tearing, melting or passing through solid neighboring cards. Stop once a modest interleaved overlap has formed. Hold both packets in that position. Do not square the deck, perform a bridge, deal cards or repeat the shuffle. No new card faces, lettering, camera move, cut or extra hand.

1. Establish, first fifth: identify each packet, its held portion and the raised meeting corners.
2. Release, middle three fifths: inspect early, middle and late releases at the central overlap; follow card edges rather than thumb speed.
3. Hold, final fifth: retain the loose interleaved overlap so the two packet origins remain distinguishable.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

• Each hand maintains its original packet instead of swapping or growing fingers around the cards.
• Raised corners relax progressively, with separate edges visible before and after release.
• Cards from both packets contribute to the overlap; one packet does not simply lie on top of the other.
• Individual visible edges remain continuous through bending, contact and settlement.
• The final overlap is stable without instant deck replacement, squaring or a bridge finish.
• If the meeting region is hidden by thumbs or blur, mark interleaving inconclusive rather than inferring it from colors.

6. Fix one failure

• The packets become two solid slabs: use fewer cards and a lower view that exposes separated edges.
• All cards release at once: ask for several distinct releases and shorten the total overlap.
• Card colors change at the center: preserve packet identity and inspect one visible edge across the overlap.
• Thumbs cover the action: revise the authorized grip and angle, keeping fingers outside the central inspection region.
• A bridge appears afterward: end explicitly at the interleaved hold and remove cinematic flourish language.

7. Ending and limits

Finish with the original two packets partially interleaved and both hands holding them still above the same mat.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 result, exact card count reconstruction, randomness test or handling proficiency assessment is supplied. Occluded card order cannot be recovered from the final stack.

The single-card task separates one rigid layer from a stationary remainder. This task forms many new alternating overlaps between two flexible packets through successive edge release. A different card back would not create another task.
