Frame Rate Guidance
| Setting | Best For | Why |
|---|---|---|
| 4K · 30fps | Interviews & showcase footage | Cinematic look with rich detail. Ideal for polished, static shots. |
| 1080p · 60fps | Action, movement & b-roll | Smooth motion at full speed; can be slowed down for slow-motion effects. |
Aperture & Exposure
Indoors / Low Light
f/2 – f/2.8
Wide aperture lets in maximum light and creates a blurred background (bokeh). Add a reflector or LED panel when using the a6400 indoors.
Outdoors / Bright Sun
f/8 – f/11
Narrow aperture reduces light and keeps more of the scene in focus. Prevents overexposure in harsh sunlight.
Outdoor Interview
f/5.6 – f/8
Middle ground — manages bright light without making the background distractingly sharp.
