WASM-Abtastung und WebCodecs

4K-Abtastung: Lanczos3, bikubisch, bilinear

Mehr Pixel sind eine größere Fläche, kein neues Gesicht und keine neue Schrift. Pixel-Wasserzeichen bleiben im Frame.

Die Qualitätsvorgaben sind Beste Qualität (Lanczos3), Ausgewogen (bikubisch) und Schnell (bilinear). Ziele sind 1080p, 1440p, 4K UHD, 2× und eine eigene Größe innerhalb der Grenzen der Steuerung. Die Optionen eines Falls sind die benutzten Regler, keine Liste von Vorgaben, die niemand gestartet hat.

Die aktuelle Abtastung arbeitet mit 8-Bit-SDR-Frames. HDR und 10-Bit-Farbe sind kein zugesagter Weg. Passendes Audio wird kopiert, wenn der Ausgabecontainer es tragen kann. Gewöhnliche Container-Tags entfallen, wenn „Metadaten entfernen“ an bleibt, und das ist die Voreinstellung.

Größere Frames ergeben meist eine größere Datei. Die Bytezahlen an jedem Fall sind die erfassten Größen. Diese Seite macht daraus keine Qualitätsnote. SIMD wird genutzt, wenn der Browser es hat; das ist keine Rate für jeden Besucher.

• Das ist kein generatives und kein Diffusions-Hochskalieren.
• Eine Zeitangabe erscheint nur, wenn die Probe dieses Falls sie aufgezeichnet hat.

Gepaarte Frames und Detailausschnitte

Diese Bilder sind die gepaarten Frames oder Detailausschnitte zu diesem Fall. Eine andere Breite oder Höhe ist die aufgezeichnete mathematische Skalierung, kein neues Bilddetail.

Für diesen Fall aufgezeichnete Grenzen

• The upscaler control is mathematical resampling (Lanczos3, bicubic, or bilinear), not a generative model.
• Capture instrumentation aborts known preexisting Cloudflare telemetry at static.cloudflareinsights.com and /cdn-cgi/rum before transmission. That block is not evidence that production has no analytics.

Gepaarte Frames und Detailausschnitte

Diese Bilder sind die gepaarten Frames oder Detailausschnitte zu diesem Fall. Eine andere Breite oder Höhe ist die aufgezeichnete mathematische Skalierung, kein neues Bilddetail.

Für diesen Fall aufgezeichnete Grenzen

• The upscaler control is mathematical resampling (Lanczos3, bicubic, or bilinear), not a generative model.
• MC-VID-001 is 64x48, about 1 second, 12 fps, and 7209 bytes. It is a limitation case, not a quality benchmark.
• Capture instrumentation aborts known preexisting Cloudflare telemetry at static.cloudflareinsights.com and /cdn-cgi/rum before transmission. That block is not evidence that production has no analytics.
