Modifying a copyrighted video (e.g., SSNI-987) without permission is a violation of the copyright holder’s right to create derivative works. Distributing or using such a modified version is illegal in most countries (DMCA in the US, Copyright Act in Japan, EUCD in Europe).

Current tools (often called "mosaic reduction" or "mosaic removal" apps) use generative neural networks:

Result: The output appears to have "reduced" the mosaic – from huge blocks to smoother, detailed-looking areas. However, details are AI-generated, not retrieved.

Example: If the mosaic covered a curve, the AI might guess a skin-colored gradient with a plausible shadow – but it could be wrong compared to the true original.

Short answer: No software can realistically restore original detail under mosaic blurring.

Mosaicking is a destructive, irreversible process. When a video encoder applies mosaic, it averages pixel blocks into larger squares, discarding fine detail permanently.

What some tools claim to do:

Results are always blurry, unrealistic, and nothing like a real uncensored video.

Sharing "reduced mosaic" content on mainstream platforms (Twitter, Reddit, Discord) results in immediate takedowns and account termination.

Combined, the user is searching for a processed version of SSNI-987 that has undergone AI mosaic reduction.

In Japan, Article 175 of the Penal Code (regarding obscenity) requires that genitalia be obscured in commercial video publications. This is why Japanese adult videos (JAV) – including those with IDs starting with SSNI (a series from the S1 studio, now rebranded as SONE) – contain mandatory mosaics. The code SSNI-987 specifically points to a JAV title released around 2019-2020.

In Japan, attempting to remove the mosaic re-introduces what the law required to be hidden. Possessing or sharing "mosaic-removed" JAV can lead to criminal charges under Article 175, with penalties including imprisonment (up to 2 years) or fines.

Before you attempt mosaic reduction on any commercial video, understand:
