Records 1,000+ fps to hyper-slow motion — crashes, fluid dynamics, combat. Frame rate and shutter angle determine quality and motion blur.
You need a high-speed camera when normal 24 fps isn't enough to show what your eye can't perceive anyway. We're talking 1,000 frames per second and up — some cameras manage 10,000 fps, some specialized cameras even 100,000+. The physics are simple: the more individual frames you capture, the slower the motion appears when you play it back at normal film speed. A water droplet that takes a tenth of a second in real-time suddenly lasts several seconds on screen.
On set, you need to keep two things in mind — frame rate and shutter angle. At 1,000 fps, you need extremely much light because each frame gets a shorter exposure time than at 24 fps. Your scene will be dark if you don't compensate with HMI ballasts or daylight spots. The shutter angle (usually 180 degrees) determines the motion blur per frame — often smaller at high-speed, leading to choppy, jagged movements. This is intentional for explosions and fight effects, but fluid shots sometimes need more shutter to look natural.
Practical Scenarios: Car crashes, glass and fluid effects, punch and fight sequences, lightning, falling objects, blood effects, pyrotechnics. High-speed is often combined with slow-motion sound design — the normal audio remains short while the image is stretched. This is crucial for believability. An explosion without the properly timed bass sounds cheap, even if the camera shoots 5,000 fps.
Storage and data rates are your enemies. One minute of footage in 4K at 1,000 fps is not rarely 2 TB. You need high-speed memory cards and dedicated SSD recorders. In the edit: the footage plays back slower in real-time, but your timeline runs at normal length — you tell the editor at how many fps you shot so they interpret it correctly. A beginner's mistake is to misinterpret the footage and double the speed instead of stretching it correctly.
Modern high-speed cameras (Phantom, Red Komodo at extreme settings, Sony FS7 with firmware tricks) deliver usable footage in acceptable quality. Older cameras? Horrendous. The optics have to keep up — fast lenses (T1.3 or better) are essential, otherwise you lose too much light. Autofocus practically doesn't work at these rates; set it to manual and rehearse beforehand.
