About Aoyama Persona
How the catalog is documented and selected.
This page explains three foundations of Aoyama Persona: Clear Generation Source, Origin Video Reference, and Selected Quality. It describes the Sora2 generation environment, the retained Origin Video, the video-based selection criteria, and the records that accompany licensed use.
01 · Clear Generation Source
Generation environment, original output, and project records.
Clear Generation Source has two components. First, the Characters were generated inside OpenAI’s own Sora product environment using Sora2. OpenAI’s published documentation describes source-identification and safety controls for that environment, including visible watermarking and likeness-related safeguards. Second, the original video from each Character’s generation is retained as a file that can be reviewed.
The Origin Video retains the visible watermark within the original Sora2 output. It is the Character-specific source record. The public OpenAI documentation describes the generation environment; the retained file records the individual output. Purchase records and the applicable License Terms document the separate facts of purchase and licensed use.
A short-lived generation environment. OpenAI released Sora2 on September 30, 2025, and discontinued the Sora web and app experiences on April 26, 2026 — a 208-day operating period. Aoyama Persona’s Origin Videos are original outputs retained from that specific OpenAI-operated environment, giving each Character a reviewable record tied to when and where it was generated rather than a later recreation.
Important
- Origin Video: The Origin Video is not a direct input asset for AI generation, processing, or training. Use the Reference Images and Voice Reference as the working inputs for permitted production workflows.
- Independent from OpenAI: Aoyama Persona is independently operated from OpenAI. The Characters offered by Aoyama Persona were generated by the Seller using Sora2. OpenAI’s published Terms of Use state that, as between the user and OpenAI and to the extent permitted by applicable law, the user owns the Output.
References to OpenAI and Sora2 are included to describe each Product’s generation source; they do not indicate affiliation, sponsorship, endorsement, or approval by OpenAI.

02 · Origin Video Reference
The Origin Video preserves information that still images cannot.
Each Aoyama Persona Character began as an original Sora2 video output. Watching and listening to that retained video gives a fuller read of the Character than a face image alone: how expression changes, how the body moves, how gestures and posture feel, how the voice sounds, how speech is paced, and how those elements combine into an overall presence.
That makes the Origin Video a substantial production reference when creating additional content as the same Character. Teams can return to the original motion-and-voice context instead of reconstructing the Character from still references alone. The Origin Video remains unchanged; the separate Reference Images and Voice Reference are used as the working inputs in compatible production workflows.
03 · Selected Quality
Selection criteria and the role of user response.
Approximately 20% were selected from around 5,500 original Sora2 generation videos. The internal review used the complete videos rather than facial stills alone, with the four criteria shown above assessed together. Separately, reactions from actual Sora2 users — including likes recorded while the sharing experience was available — were used as an external selection signal. Selection therefore reflects both full-video internal review and a distinct real-user perspective.
Real Sora2 user response — a separate external selection signal
Selection was not based on Aoyama Persona’s internal review alone. Reactions recorded while Sora2’s sharing experience was available — including likes from actual users outside the selection team — show how viewers responded to the original generated videos in that environment. They were used as a separate external selection signal alongside, not instead of, the internal full-video review.
04 · Professional-use Support
Three supporting elements for professional use.
Clear license terms, a retained purchase record, and a standardized four-file package give teams a consistent basis for reviewing what was purchased, how it may be used, and what files belong with each licensed Character.
01 · License Terms
License scope
The License Terms identify the licensed subject as the fictional AI Character and specify how the Buyer and permitted Client work may use it.
Published termsLicense Terms outline commercial use, Client-work scope, non-exclusive status, and other conditions before purchase.
02 · Purchase Records
Purchase and later access
Purchase confirmation is retained through the Gumroad receipt email and Gumroad’s purchase-access functions.
Gumroad purchase recordKeep the Gumroad receipt email and Order ID. Purchase details can be reviewed on the download page accessed from the receipt. If you use a Gumroad account, purchased products can also be reviewed in your Library.
03 · Standardized Package
The four-file structure
Each licensed Character follows the same core package structure so teams know what to expect before purchase.
Four-file structure1 Origin Video serving as both source record and Character reference, plus 2 Reference Images and 1 Voice Reference for each Individual Character.
Keep the records together.
Keep the original files, Gumroad receipt email, Order ID, and the License Terms applicable at the time of purchase together with your internal or project records.
05 · External Context
Optional public references on source transparency.
These external sources provide broader context for source transparency, watermarking, and synthetic-media disclosure. They are supplementary to Aoyama Persona’s narrower Character-specific generation-source information: the retained Origin Video and Visible Watermark.
European CommissionPublic work on AI-generated content provides broader context for transparent identification and disclosure frameworks.
NISTProvenance tracking, watermarking, and metadata are recognized approaches for improving transparency around synthetic content.
U.S. Copyright OfficePublic AI studies provide broader context for how synthetic content and realistic digital replicas are reviewed.

Purpose
The Character is the licensed subject
A purchase grants a non-exclusive license to the fictional AI Character or Characters within the selected Product. The four accompanying files support that licensed use; Individual, Volume, and Complete purchases simply organize the same catalog into different purchase units.
Workflow
Review → create → deliver completed work
Review the Origin Video for the Character’s original motion-and-voice context, use the Reference Images and Voice Reference as the working inputs, and create within the permitted production workflow. For Client projects, the Buyer remains the license holder and delivers Completed Works; further Character-based production and revisions remain with the Buyer as license holder.
