So prüfst du die Qualität eines YouTube-Thumbnails vor der Nutzung
Praktische Checkliste für Schärfe und Eignung vor der Wiederverwendung.
Bevor du ein Thumbnail als Referenz nutzt, solltest du die Qualität kurz prüfen.
Start with the largest available image
Always inspect the highest resolution first.
If the largest version looks weak, smaller versions will not improve quality.
Inspect text and edge sharpness
Zoom in and verify that text edges are readable, not smeared.
Look at faces, logos, and high-contrast lines for compression noise.
Check real usage size

Preview it at the size you plan to use before finalizing.
- Test at 100% zoom.
- Check on both light and dark backgrounds.
- Avoid aggressive upscaling.
Document source and intent
Save where the image came from and why it was used.
