System Requirements Document for animation-video

1. Introduction

animation-video creates a short animated vertical reel from the user-supplied outfit-of-the-day image. The image shows a yellow ruffle top, heart-check shorts, and handwritten callouts. The outfit remains still while elements around it animate, producing a 10–15 second video with gentle zooms, floating hearts, animated arrows, and outfit details appearing one by one.

The current audience is the Content Creator who supplies the image and receives the finished animation.

2. System Overview

The system is a custom application with an anonymous public entry and application-owned identity for protected animation work. The Content Creator can enroll, return and verify their identity, create an animation from the supplied image, preview the generated video, and play the finished video.

Current accepted behavior is limited to the supplied image and its specified animation treatment and format. The outfit itself does not move or transform. No additional editing, publishing, sharing, or account-management capabilities are specified.

2a. Product Interpretation and Delivery Boundary

The application provides the accepted animation workflow through the six contracted pages: Landing, Sign Up, Login, Animate, Preview, and Playback. Landing, Sign Up, and Login are anonymously reachable. Animate, Preview, and Playback require login so the creator’s work remains associated with the correct identity. Enrollment and returning verification are prerequisites for protected work, not additional account-management features.

The supplied outfit image is the authoritative content source for the animation. The generated video must be a 10–15 second vertical reel, with the outfit static and its surrounding elements animated as specified. No future requirements are identified.

2c. Page Content and Component Coverage

Landing

• Information and state: Public introduction to turning the supplied outfit image into a short animated reel. Show the source image as the hero artifact and communicate the 10–15 second vertical format and accepted motion treatment.
• Primary and supporting actions: A clear route to Sign Up for a creator ready to begin; a separate route to Login for a returning creator. A motion-sampler strip may demonstrate the accepted hearts, arrows, and callout motion without introducing additional behavior.
• Domain entities: Source outfit image; animation treatment; reel format.
• Components: Taped-photo hero composition; oversized product headline; callout tags and motion sampler; navigation to Sign Up and Login.
• States: Loading displays the available source image or a clear image-loading state. Empty or unavailable source imagery is identified rather than replaced with unrelated imagery. Success presents the product and its accepted treatment. Errors in loading the image or sampler are communicated; recovery is to retry or continue to the relevant access page without implying the animation has been created.

Sign Up

• Information and state: Anonymous self-service enrollment needed before protected animation work. No additional profile fields or account-management functions are specified.
• Primary and supporting actions: The Content Creator provides the information required to establish application identity and submits enrollment; can return to Landing or go to Login if already enrolled.
• Domain entities: Creator identity; enrollment result.
• Components: Enrollment form, submission feedback, and navigation to Landing or Login.
• States: Loading indicates submission in progress. Empty state presents the enrollment form. Success confirms identity establishment and continues to Animate. Invalid or failed enrollment explains that access was not established and allows correction or retry. No protected work is exposed before successful enrollment.

Login

• Information and state: Anonymous returning verification for access to the creator’s previously created animation work.
• Primary and supporting actions: The Content Creator provides verification information and submits; can return to Landing or Sign Up.
• Domain entities: Creator identity; verification result; associated animation work.
• Components: Verification form, submission feedback, and navigation to Landing or Sign Up.
• States: Loading indicates verification in progress. Empty state presents the form. Success continues to protected work. Failed verification explains that access was not granted and allows correction or retry. Protected work remains unavailable until verification succeeds.

Animate

• Information and state: Protected workspace for the supplied outfit image and the accepted animation specification: 10–15 seconds, vertical reel, gentle zooms, floating hearts, animated arrows, and outfit details appearing one by one. The outfit remains static; elements animate around it.
• Primary and supporting actions: The Content Creator starts creation using the supplied image and accepted treatment. The workspace presents the source image and the resulting generation status.
• Domain entities: Source image; animation treatment; generated video; creator-owned work.
• Components: Source image pinned as the central artifact; horizontal film-sprocket timeline strip with animation-state labels; treatment details; generation status and continuation to Preview when a result is available.
• States: Loading identifies image or generation processing. Empty state explains that the source image is not available to the workspace and provides a retry/recovery path; it does not substitute unrelated imagery. Success indicates a generated video meeting the required duration, orientation, and treatment, and offers continuation to Preview. Generation failure is visible and permits retry from the same accepted source and treatment. Protected state requires login.

Preview

• Information and state: Protected preview of the generated 10–15 second vertical animation before it is treated as finished.
• Primary and supporting actions: The Content Creator views the generated video and proceeds to Playback when ready. If the video is unavailable or generation failed, the creator can return to Animate to recover by retrying creation.
• Domain entities: Generated video; preview state; creator-owned work.
• Components: Video preview, format/treatment context, status and continuation to Playback or Animate.
• States: Loading indicates preview preparation. Empty state explains that no generated video is available and routes back to Animate. Success presents the preview. Playback or preview errors are communicated and can be retried; if the video cannot be recovered, return to Animate. Protected state requires login.

Playback

• Information and state: Protected destination for playing the finished animation video.
• Primary and supporting actions: The Content Creator plays the finished video and can return to Preview.
• Domain entities: Finished generated video; playback state; creator-owned work.
• Components: Video playback surface, playback status, and return to Preview.
• States: Loading indicates video preparation. Empty state explains that no finished video is available and routes to Preview or Animate as appropriate. Success plays the finished video. Playback failure is communicated and permits retry or return to Preview. Protected state requires login.

3. Functional Requirements

1. As a Content Creator, I should be able to understand the animation-video outcome from the public entry.

   • Provenance: required_inference (Landing page contract).
   • Lifecycle: From anonymous Landing, the creator sees that the product turns the supplied outfit image into a 10–15 second vertical animated reel with the accepted motion treatment. The creator chooses Sign Up to begin or Login to return to existing work.
   • Observable acceptance: Landing communicates the product purpose and routes to the corresponding access page. If the source image cannot load, the page communicates that state and does not substitute unrelated imagery.
   • Access: Anonymous.

2. As a Content Creator, I should be able to establish an identity before creating protected animation work.

   • Provenance: required_inference.
   • Lifecycle: From anonymous Sign Up, the creator submits the information needed for self-service enrollment. Successful enrollment establishes identity and continues to Animate. Failed or invalid enrollment leaves protected work unavailable and allows correction or retry.
   • Observable acceptance: Enrollment success is confirmed and the creator can continue to Animate; failure is visible and recoverable.
   • Access: Sign Up is anonymous; protected work requires successful identity establishment.

3. As a Content Creator, I should be able to verify my identity when returning to previously created animation work.

   • Provenance: required_inference.
   • Lifecycle: From anonymous Login, the creator submits verification information. Successful verification restores access to their protected work; failed verification leaves it unavailable and allows correction or retry.
   • Observable acceptance: The creator receives a clear success or failure result, and protected work is accessible only after successful verification.
   • Access: Login is anonymous; protected work requires successful verification.

4. As a Content Creator, I should be able to create an animation video from the supplied outfit-of-the-day image.

   • Provenance: explicit for creating from the supplied image; required_inference for making the image available in the workspace and associating the resulting work with the creator.
   • Lifecycle: From authenticated Animate, the creator starts creation using the supplied image. The system generates a video with the outfit static and the image’s elements animated around it. A successful result is available in Preview; if the image is unavailable or generation fails, the creator sees the failure and can retry using the accepted source and treatment.
   • Observable acceptance: The generated video is based on the supplied image; the outfit does not move or transform; the creator sees generation status and can continue to Preview on success.
   • Access: Login required.

5. As a Content Creator, I should receive a 10–15 second vertical reel.

   • Provenance: explicit for duration and vertical reel format; required_inference for validating that the generated result satisfies them.
   • Lifecycle: During creation, the system produces and makes available a video that is 10–15 seconds long and vertical. If generation does not produce a result meeting these constraints, the creator is not shown it as a successful completed result and can retry.
   • Observable acceptance: The available generated video satisfies both duration and orientation constraints.
   • Access: Creation and result are protected by login.

6. As a Content Creator, I should receive the specified animation treatment around the outfit.

   • Provenance: explicit.
   • Lifecycle: During creation, the system applies gentle zooms, floating hearts, animated arrows, and outfit details appearing one by one. The outfit itself remains static; the image’s elements animate around it. The creator can inspect the result in Preview. If generation fails, the creator sees the failure and can retry.
   • Observable acceptance: The generated video includes the specified motion treatment without transforming or animating the outfit itself.
   • Access: Creation and preview are protected by login.

7. As a Content Creator, I should be able to preview the generated video before treating it as finished.

   • Provenance: required_inference (Preview page contract).
   • Lifecycle: From authenticated Preview, the creator views the generated video. On success, the creator can continue to Playback. If no video is available or preview fails, the creator sees the state and can retry or return to Animate to recover.
   • Observable acceptance: Preview presents the generated video when available and does not represent a missing or failed result as successful.
   • Access: Login required.

8. As a Content Creator, I should be able to play back the finished animation video.

   • Provenance: required_inference (Playback page contract).
   • Lifecycle: From authenticated Playback, the creator plays the finished video. On playback failure, the creator can retry or return to Preview; if no finished video is available, the creator is directed to the appropriate earlier step.
   • Observable acceptance: The finished video is playable when available, and playback failure or missing video is communicated with a recovery path.
   • Access: Login required.

4. User Personas

Content Creator

• Provenance: required_inference, as identified in Planning Scope from the explicit request to create a video from the supplied image.
• Product context: A creator turning a supplied outfit-of-the-day image into a short vertical reel. The source image contains a yellow ruffle top, heart-check shorts, and handwritten callouts.
• Primary goal: Receive a completed 10–15 second vertical animation video based on the supplied image.
• Distinct responsibilities: Establish identity before protected work; provide or use the supplied image in the animation workspace; initiate creation with the accepted treatment; inspect the generated result in Preview; play the finished video.
• Relevant inputs and decisions: The supplied image and the accepted format and motion treatment. The creator decides to begin creation, whether to proceed from preview to playback, and whether to retry after a material failure.
• Interaction with other participants: No other accepted human participant is involved. The application performs generation and presents its result to the creator.
• Observable success: The creator can access a generated 10–15 second vertical reel in which the outfit remains static while gentle zooms, floating hearts, animated arrows, and outfit details appearing one by one animate around it.

5. Core User Flows

1. Understand the product and choose an access path

1. The Content Creator opens Landing anonymously.
2. Landing presents the supplied outfit image and explains the short vertical animation outcome and its accepted treatment.
3. The creator chooses Sign Up to begin creating protected work, or Login to return to existing work.
4. If the image or motion sampler fails to load, Landing communicates the issue; the creator can still choose an access path.

2. Establish identity and begin animation work

1. The Content Creator opens Sign Up anonymously and submits the information needed for self-service enrollment.
2. On success, the application confirms identity establishment and continues to Animate. On failure, the creator corrects the information or retries; protected work remains unavailable until enrollment succeeds.
3. In Animate, the creator starts creation using the supplied outfit-of-the-day image.
4. The system generates a 10–15 second vertical reel. The outfit remains static; gentle zooms, floating hearts, animated arrows, and outfit details appearing one by one animate around it.
5. On success, Animate presents the result and the creator continues to Preview. If the image is unavailable or generation fails, the creator sees the failure and can retry with the accepted source and treatment.
6. In Preview, the creator inspects the generated video before treating it as finished. If preview is unavailable or fails, the creator can retry or return to Animate.
7. The creator continues to Playback and plays the finished video. If playback fails, the creator retries or returns to Preview.

3. Return to previously created animation work

1. The Content Creator opens Login anonymously and submits verification information.
2. On successful verification, the application restores access to the creator’s protected work. On failure, the creator sees that access was not granted and can correct the information or retry.
3. The creator opens the relevant protected destination—Animate, Preview, or Playback—to continue the accepted animation workflow. Protected work remains unavailable until verification succeeds.

6. Visuals Colors and Theme

The visual direction is Handmade provocation: the outfit is the artifact, the page is the film set, with Stefan Sagmeister as the named muse. The headline is “ANIMATE YOUR OOTD”, with “OOTD” knocked out in yellow on a red block. The interface should feel like a tactile, playful creator workshop, not a sterile video tool.

Color tokens

Use approximately 60% cream ground, 25% off-white surface, 10% ink, and 5% red/yellow accents. No blue or indigo.

Typography and type scale

• Display and headings: Alfa Slab One. Display headlines use tight tracking (-0.02em), all-caps or title case, and viewport-spanning scale: clamp(64px, 10vw, 120px). Display line-height: 0.95.
• Body and UI: Space Grotesk, medium weight, generous line-height (1.55).
• Labels and buttons: Space Grotesk uppercase with 0.08em tracking.
• Scale: Display 64px mobile / 120px desktop; H1 40px / 56px; H2 28px / 36px; body 16px / 18px; labels 12px.

Shape, layout, and imagery

• Use sharp-cornered cards and buttons, 2px ink borders, and 4px offset red shadows; keep radii at or below 4px except pill-shaped play controls.
• Use occasional 2–4 degree rotations for callout tags and hearts. Thick 3px rules may separate sections.
• Use an asymmetric editorial grid with a dominant seven-column image/preview area and a narrower four-column controls/detail area. In Animate, pin the source image on the left, place the film-sprocket timeline across the bottom, and stack treatment details on the right. On mobile, stack image, timeline, then details.
• Present the supplied photo as a physical artifact with tape corners and a hard red offset shadow. Preserve and re-animate its handwritten callouts. Supporting visual materials may evoke torn paper, masking tape, and screen-print texture; do not introduce unrelated stock imagery or 3D renders.
• Keep readable text and controls fully within the viewport and their containers at 375px, 768px, and 1280px. Wrap or scale content as needed; decoration may crop or overlap only when it does not cover readable text or controls.

Motion styling

Use a stop-motion, frame-based feel. UI transitions use stepped reveals at 12fps rather than smooth easing. Hearts drift upward with slight rotation and a stepped 0.2-second fade; arrows draw on with hand-drawn stroke-dashoffset motion; detail callouts appear one by one with a two-frame overshoot. The source image may use a gentle Ken Burns zoom of 0.05 scale over 10 seconds. Hover states flip the offset shadow from red to yellow.

7. Signature Design Concept

The public Landing page is a full-bleed cream studio wall. The supplied outfit photo is the hero artifact, positioned center-left at roughly 60% of the viewport height, held by two strips of masking tape at its top corners and casting a hard red offset shadow. Above it, the large Alfa Slab One headline reads “ANIMATE YOUR OOTD”, with “OOTD” in yellow on a solid red highlight block. To the right of the photo, three handwritten-style callout tags float upward and fade, demonstrating the accepted motion treatment. Below the photo, a single ink-black pill-shaped play control has a red offset shadow. A motion-sampler strip can show the accepted hearts, arrows, and callout animation. The composition should read as a physical pinboard, not a centered SaaS hero.

8. Interaction Model & Motion Direction

Interaction Model: Animated
Motion Tempo: expressive
Hero Dimensionality: flat

Landing Hero Motion Brief

• Focal subject: The supplied outfit-of-the-day photo, presented as a taped-down artifact on a cream studio wall.
• Input → transformation → outcome thesis: The creator brings the supplied still image into the animation workflow; the outfit stays still while its surrounding callouts and details receive the accepted motion treatment; the outcome is a short vertical animated reel.
• Motion vocabulary: Stop-motion and frame-based reveals at 12fps; floating hearts drift upward with slight rotation and stepped fade; arrows draw on with hand-drawn strokes; callouts appear one by one with a two-frame overshoot. No parallax or 3D.
• Composed first frame: Cream ground; large headline above the taped photo; three callout tags to the right; play control below. Keep all readable text and controls fully visible at supported viewport widths.
• Reduced-motion state: Stop decorative motion. Render hearts and arrows as static SVG and show a manually controlled scrubber for the preview.

9. Non-Functional Requirements

1. Format compliance: Generated video must be 10–15 seconds and vertical. Provenance: explicit in Planning Scope. Rationale: These are hard output constraints.
2. Outfit immobility: The outfit itself must not move or transform; animate image elements around it. Provenance: explicit in Planning Scope. Rationale: This is an explicit constraint on the animation treatment.
3. Responsive readability: Readable text and controls must remain whole and unobscured at 375px, 768px, and 1280px; imagery and decoration may crop or overlap only as specified in the creative direction. Provenance: authoritative Creative Direction.
4. Reduced motion: With prefers-reduced-motion, decorative motion stops, hearts and arrows render as static SVG, and the preview shows a manually controlled scrubber. Provenance: authoritative Creative Direction.
5. Protected-work continuity: Previously created animation work is available only after returning verification. Provenance: required_inference from application-owned identity and the accepted returning-work journey.
