Stop the Strobe: Flicker Free Calculator
LED lights and fluorescent tubes flicker at the frequency of the AC power grid (50Hz or 60Hz). If your shutter speed doesn't align with this pulse, you get ugly banding lines rolling down your video. The **Ficker Free Calculator** tool at **Online Tool Base** gives you the "Safe Shutter Speeds" to eliminate this artifact.
Shooting in Europe (50Hz)? You need 1/50 or 1/100. Shooting in USA (60Hz)? You need 1/60 or 1/120. **onlinetoolbase.online** simplifies this, providing a list of safe speeds and Shutter Angles relative to your frame rate.
Why Use This Tool?
Flicker is often invisible to the naked eye but ruins slow-motion footage. Once recorded, it is extremely difficult to fix in post. Checking this tool before you hit record ensures clean, professional footage, especially when shooting under cheap stadium or street lighting.
Key Features
- Region Selector: NTSC (60Hz) vs PAL (50Hz) zones.
- Shutter Angle: Supports cinema camera notation (e.g., 172.8°).
- Safe List: Green-lit speeds that sync with the grid.
How to Use
- Select Power Frequency (50Hz or 60Hz).
- Select Camera Frame Rate.
- The tool lists valid Shutter Speeds.
- Match your camera settings to the list.
