RenderProof: A video delivery agent that refuses to guess

Description and use

RenderProof is an agent that delivers verified codec and container recommendations by querying a Sanity Knowledge Base, exposing conflicts instead of guessing.

Problem

Video encoding advice is often generic and ignores version, dependency, and conflict nuances, leading to unreliable FFmpeg commands.

Outcome

RenderProof delivers accurate, evidence-backed FFmpeg recommendations, exposing conflicts instead of guessing, thereby improving reliability for video encoding workflows.

Workflow

• 1. User asks a question about codec/container compatibility.
• 2. RenderProof retrieves relevant records from Sanity via MCP.
• 3. It checks compatibility rules and source claims.
• 4. If a conflict exists, it reports the conflict instead of guessing.
• 5. If a single supported claim exists, it returns the recommendation with citations.
• 6. The answer streams to the UI with tool activity logs.

Evidence

RenderProof takes a different approach. It treats Sanity as the source of truth for structured claims, compatibility rules, delivery profiles, pipeline recipes, and editorial decisions.

Source

One deliberately tested example is libx264 with nal-hrd=cbr and MP4. The captured FFmpeg documentation says the combination is not allowed in MP4.
