The "Silent Shooting" Trap

You can turn on Silent Shooting (Menu → Camera 1 → Shutter Type → Electronic). It's great for concerts and sleeping babies. However: Under fluorescent lights or LED screens, you will get banding (dark lines across the image). If you see banding, turn it back to Mechanical.

The Best Video Settings:

• Format: File Format → XAVC S 4K.
• Record Setting: 24p 100M (for cinematic look) or 30p 100M (for vlogging).
• Auto Power OFF Temp. (Crucial): By default, the camera overheats after 20 minutes of 4K. Fix this: Menu → Setup → Auto Power OFF Temp. → High. It will now record until the battery dies.
• Picture Profile: You have two paths.
  • Lazy/Great: PP10 (HLG2). This gives you HDR video. It looks flat but retains highlights. No grading needed beyond a basic SDR conversion.
  • Pro: PP8 (S-Log3). Requires heavy color grading. Warning: The a6400 has 8-bit color, not 10-bit. S-Log3 can get banding in the sky. Use S-Log2 (PP7) instead for 8-bit safety.

Scenario C: Low Light / Night (Manual Mode - M)

• Goal: Let in as much light as possible without introducing "noise" (grain).
• Aperture: Lowest f-number.
• Shutter Speed: Slow (e.g., 1/30s or slower), but use a tripod!
• ISO: Keep it under 3200. If you go above 3200, the image will get grainy.
