Manual video on a mirrorless camera comes down to a few linked settings: frame rate, shutter speed, aperture, ISO and white balance. Set them once for a scene, keep them steady while you record, and your footage will look consistent and easy to edit.
The Core Settings
Menu names differ between brands, but the ideas are the same everywhere. Treat the numbers below as general guidance and adjust to your camera and taste.
- Frame rate: Choose the look you want. 24 frames per second gives a film-like feel, 30 is common for general video, and 60 or higher is useful for slow motion.
- Shutter speed: A common rule is to set it to about double the frame rate. At 24 fps, that means roughly 1/50. This keeps natural motion blur.
- Aperture: This controls depth of field and light. A wide opening such as f/2.8 gives a soft background; a narrower one such as f/5.6 keeps more in focus.
- ISO: Keep it as low as the light allows. Higher values add noise, though modern cameras handle moderate values well.
- White balance: Set a fixed value in Kelvin, or use a preset, instead of leaving it on auto, so color does not drift mid-shot.
A Simple Setup Order
- Switch the camera to video mode and select manual exposure.
- Pick your resolution and frame rate, and keep them the same for all clips in a project.
- Set the shutter speed to about twice the frame rate.
- Choose an aperture for the depth of field you want.
- Adjust ISO until the exposure looks right on the screen or histogram.
- Set white balance for the light in the scene.
- Check focus, then record a short test clip and look it over on a larger screen.
When Light Is Too Bright
Because the shutter speed is tied to the frame rate, you cannot simply speed it up in bright light without changing the look. Instead, use a neutral density filter. It reduces the light reaching the sensor, so you can keep a wide aperture and the shutter speed you want. A variable ND filter is convenient for changing conditions, though a fixed one often keeps image quality more predictable.
Useful Tools on the Camera
| Tool | What it shows |
|---|---|
| Histogram | Overall brightness distribution |
| Zebra stripes | Areas that may be overexposed |
| Focus peaking | Edges that are in focus |
| Waveform | Exposure across the frame, where offered |
FAQ
Should I use autofocus while recording?
Many modern mirrorless cameras have reliable video autofocus, and it is a fine choice for moving subjects. For controlled shots, manual focus gives a more deliberate result.
Why does my footage flicker indoors?
Artificial lights can pulse, and a shutter speed that does not match the mains frequency can show banding. Try a slightly different shutter speed or a flicker-reduction setting, if your camera has one.
The Short Version
Choose a frame rate, set the shutter speed to about double that, pick an aperture for the look, and adjust ISO for exposure. Lock white balance and use an ND filter in bright light. Practice with short clips until the sequence feels natural.
