How the result is calculated
Canvas carries locally decoded video frames into MediaRecorder while Web Audio routes decodable source audio. The page requests an actual MP4 container with browser-provided H.264 and audio encoding; it never relabels WebM. Current Chrome or Safari support is required, and input codec support, exact timing, quality and file size depend on the browser.
Read the current MDN MediaRecorder format-support documentation before submitting.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
Important limitations
Results are provided for convenience and should be checked independently before an important decision. A format or checksum result never authenticates an identity, document, account, licence, vehicle or registration.
