Turn three portrait photos into a tactile album film with curved pages, occlusion and two visible turns. Three atlas panels become page textures. A subdivided mesh bends around a cylinder and rotates at the spine; perspective-correct texture sampling and a depth buffer show the curling page over the next photograph. The reverse side reuses the same image rather than inventing unseen content. Reuse supplied assets or quote new media through PopNow.

v1.0.0 · Updated Oct 25, 2026 · 5.5 MB · Use it for personal and client work; please don't resell or share the package.

What you get

  1. An editable 8-second 720p sample and local MP4 renderer, silent.

  2. The atlas crop, page geometry, two turn timings and depth-tested texture rendering are prepared. Your photos remain attached to their page surfaces through each turn instead of being cross-faded as flat cards.

  3. A six-frame contact sheet, render receipt and input self-check.

Good for

  • Travel journals, photo memories and personal story openers
  • Tactile photo-album transitions with editable page timing

Not for

  • The package uses a prescribed cylindrical page motion, not a paper mechanics solver. The reverse face repeats its photo, and the three-panel atlas is the supported input layout.

How it works

Includes a local renderer

  1. Choose the material

    Provide one atlas containing exactly three equal-width portrait panels. The supplied original travel triptych is a working example; replace it with owned photos assembled in the same layout.

  2. Shape the motion

    Edit the documented project controls, then validate the exact settings. Replace pages_atlas with three equal-width portrait photographs.

  3. Render and review

    Export locally to MP4, inspect the contact sheet and watch the whole film. Check both turns for clipped subjects, page occlusion and atlas seams, then confirm the final spread is readable.

How the workflow runs

How Page Curl Memory Film works

Three atlas panels become page textures. A subdivided mesh bends around a cylinder and rotates at the spine; perspective-correct texture sampling and a depth buffer show the curling page over the next photograph. The reverse side reuses the same image rather than inventing unseen content.

What's inside the skill

What you can change

  • Replace pages_atlas with three equal-width portrait photographs.
  • Curl amount from 0.25 to 1.3 changes the page's cylindrical bend.
  • Turn duration from 1.4 to 2.7 seconds controls each of the two page turns.

What to review before delivery

  • The local self-check compares three frame samples after a meaningful input change and rejects its documented invalid case.
  • Output protection rejects overlap with input files and preserves existing sidecars unless overwrite is explicit.
  • Check both turns for clipped subjects, page occlusion and atlas seams, then confirm the final spread is readable. This final visual review is manual.

Why use this skill

Start with this package

The atlas crop, page geometry, two turn timings and depth-tested texture rendering are prepared. Your photos remain attached to their page surfaces through each turn instead of being cross-faded as flat cards.

What PopNow adds

Use PopNow for the missing Images, Music & voice in this workflow. Keep adequate material you already own, then bring new assets back into the editing and assembly steps described here.

Compare the options

A prompt, your own skill, or this workflow?

Start with a prompt

Your agent can create from a plain request. The brief, visual rules, asset choices, output format and review process still need to be established for that project.

Write your own skill

You choose and maintain the reusable instructions, defaults, file structure and checks. This is useful when your process needs different rules or integrations.

A workflow created for PopNow

This workflow was built for PopNow. Its source files, included dependencies and applicable notices are part of the package; the scope described below belongs to this edition.

Guide reviewed Oct 25, 2026

What will this cost?

Existing photographs are cropped and rendered locally. If one of the three panels is missing, quote that new image through PopNow before creating it; optional music is a separate request. The supplied example does not need another generation run.

Generation is optional when you have suitable input material. Free skill. New media is quoted before it runs.

The skill package

Free to install under your account's download allowance. The package license covers your own and client work; redistribution is excluded.

Existing assets and local work

Reusing suitable assets, editing files and running local assembly do not call a PopNow generation model. Your computer and any required runtime still do the work.

New AI images, clips or sound

Quoted for the actual model, inputs, count, duration and resolution. Extra alternatives, revisions or optional enhancement passes can add generation requests.

Your agent and hosting

Any subscription, hosted computer, deployment or other provider fee belongs to that service. Installing this skill does not include those services.

Check the cost of your version first

Your assistant can inspect the available models and quote the exact request first. You choose which optional passes to include and approve spending before generation.

Ask your assistant

  • Use the PopNow skill "Page Curl Memory Film" for my project. List the inputs you can reuse, quote only the missing media, show the quoted total and flag any unpriced steps. Separate optional enhancements, and wait for my approval before starting anything paid.

How PopNow billing works

Connections using a PopNow API key, including API-key MCP connections, spend from the separate API balance in USD. A ChatGPT or Claude connection authorized through OAuth spends website credits. These balances are separate; the quote shown by your connection is the approval basis.

Download allowances and current account conditions apply. A free package does not mean unlimited free generation.

How to use it

You say

  • Use the PopNow skill "Page Curl Memory Film" (page-curl-memory-film) for this: Make an 8-second album film from the supplied three-panel atlas, then replace it with my travel photos. Show both page turns and a readable final spread; quote only missing images or optional music.

Then try

  • Show how the changed setting affects the actual motion.

  • Keep my adequate source material and prepare an optional soundtrack quote.

What to have ready

  • Provide one atlas containing exactly three equal-width portrait panels. The supplied original travel triptych is a working example; replace it with owned photos assembled in the same layout.
  • Python 3, Pillow, NumPy, FFmpeg and ffprobe
  • The project controls listed in the input contract

Questions

Can I use three separate photos?

Assemble them into the documented equal-width, three-column atlas first. The renderer reads that local atlas and preserves each panel as a page texture.

Does it generate the hidden side of a page?

No. The reverse side reuses the page photograph. It does not infer or generate an unseen back image.

Is the curl a physical paper simulation?

No. A cylindrical bend and a spine rotation define the motion. The texture and occlusion are rendered from that geometry.

What is already packaged in Page Curl Memory Film?

The task-specific motion mechanism and supported inputs. Protected MP4 export, contact sheet and hash receipt. Editable settings used by the supplied sample. Actual changed-frame, invalid-input and output-protection checks. Input ranges, material placement and honest limits.

Which parts of Page Curl Memory Film can add a charge?

Existing photographs are cropped and rendered locally. If one of the three panels is missing, quote that new image through PopNow before creating it; optional music is a separate request. The supplied example does not need another generation run. Connections using a PopNow API key, including API-key MCP connections, spend from the separate API balance in USD. A ChatGPT or Claude connection authorized through OAuth spends website credits. These balances are separate; the quote shown by your connection is the approval basis.

How does Page Curl Memory Film differ from writing a prompt or my own skill?

The atlas crop, page geometry, two turn timings and depth-tested texture rendering are prepared. Your photos remain attached to their page surfaces through each turn instead of being cross-faded as flat cards.
