Face & ID Verification
Why Your Webcam May Appear Grainy (and How to Improve It)
If your webcam preview looks grainy, dark, or low quality, it may affect facial visibility during face capture. Poor webcam clarity can lead to verification issues or unnecessary flags during your Talview test.
✅ Common Causes and Fixes
| What Might Be Wrong | What You Can Do |
|---|---|
| Low lighting in the room | Sit in a well-lit room, preferably with natural light or a lamp facing you. Avoid backlighting. |
| Dirty or smudged webcam lens | Gently clean the webcam lens with a soft cloth before starting the test. |
| Webcam resolution is set too low | Close all apps using your camera, then restart the test. |
| Using a low-end or external webcam | Use your built-in laptop webcam if possible — they usually offer better quality for proctoring. |
| Background is too dark | Sit against a neutral-colored wall in a well-lit space to avoid contrast issues. |
| Internet speed is unstable | Graininess may appear if video is compressed. Run a speed test and ensure stable connection. |
