ISO Budget and Native ISO
Native ISO is camera's optimal sensitivity. Modern cameras: ISO 100-400 clean; ISO 800-3200 acceptable; ISO 6400+ noisy.
Native ISO by camera
Sony A7S III: native ISO 640 / 12800 (dual native)
Canon R5: ISO 100-1600 clean
Sony A7 IV: ISO 100-1600 clean
Fuji XT-5: ISO 200-1600 clean
Blackmagic Pocket 6K: ISO 400 / 3200 native
Smartphone (iPhone 15 Pro): ISO 50-400 best
Know your camera's native ISO for cleanest video.
ISO budget rule of thumb
For most modern cameras:
- ISO 100-400: pristine
- ISO 800-1600: clean
- ISO 3200: acceptable for color
- ISO 6400: visible noise but usable
- ISO 12800+: noisy, use only when necessary
Push ISO when light is limited; otherwise stay low.
Noise reduction tools
If forced into high ISO:
- In-camera — most have noise reduction option
- DaVinci Resolve — built-in noise reduction (paid Studio)
- Neat Video — specialized noise reduction plugin
- AI-based — Topaz Video AI, others
Reduce noise in post when shot at high ISO.
