Why Cinematic Motion Blur Matters
Most smartphone videos look like they were taken on a phone instead of a dedicated camera. The difference often boils down to manual control and the 180-degree shutter rule—elements that cell phones set to “AUTO” simply don’t prioritize. Today’s phones let you adjust settings like shutter speed and ISO, but if you truly want that “cinematic” feel, a VND is essential.
The 180-Degree Shutter Rule Explained
To get smooth, film-like motion blur, your shutter speed should be twice your frame rate. This guideline is known as the 180-degree shutter rule.
- Shooting at 30 FPS? Choose a 1/60 shutter speed.
- Shooting at 24 FPS? Go for 1/48 (or the closest option like 1/50).
Without a Variable ND Filter, bright outdoor settings force your phone to increase shutter speed, creating choppy or overly sharp video. A VND keeps your shutter locked at the ideal speed for silky smooth motion.
Enter the Moment VND QuickLock Filter
Moment’s QuickLock VND (2–7 stops) is built around user-friendly design and versatility, allowing you to fine-tune light reduction whether you’re filming under the harsh midday sun or capturing the softer hues of golden hour. Its unique QuickLock system uses a simple red button mechanism that snaps securely into a Moment camera case, enabling easy press-and-twist removal whenever needed.
Rather than fumbling with traditional threads or clips, the opposite side of the red button features a small dial for smooth, on-the-fly adjustments to the filter’s density, so you don’t have to juggle multiple separate filters. Slim enough to stay on your device all day, it avoids unnecessary bulk while ensuring the highest level of control over your exposure and motion blur.
