Video quality varies wildly (from 240p to 4K). A verified MP4 ensures the file meets a specific standard (e.g., 1080p or 720p with proper bitrate) rather than a low-quality re-encode.
| Stakeholder | What “Verified” Means for Them | |-------------|--------------------------------| | Design Engineers | Validation that design assumptions hold; feedback loop for future revisions. | | Quality‑Assurance Teams | A concrete artifact (certificate, traceability matrix) to satisfy internal audits and external regulators. | | Regulators | A transparent, auditable trail demonstrating compliance with safety and EMC standards. | | Customers/End‑Users | Confidence that the device will perform reliably under advertised conditions. | | Supply‑Chain Partners | Clear specification of test criteria, simplifying acceptance testing of sub‑components. |
