Slow Motion Video Frame Rates: 60p, 120p, 240p

Understanding high frame rates

Video is a sequence of still frames shown in quick succession. The frame rate, measured in frames per second (fps), determines how motion is captured. A standard broadcast rate is usually 24p or 30p, which looks natural for dialogue and everyday scenes. When you raise the frame rate to 60p or above, you are capturing more temporal detail, so the action can be slowed down smoothly in editing. If you are new to the concept, our video frame rate guide explains the fundamentals.

For slow motion, you record at a high frame rate and then conform the footage to a normal timeline. For example, footage recorded at 120p and played back on a 30p timeline runs at one quarter speed. The extra frames fill in the gaps, preventing the stutter you get when you slow down footage recorded at a standard rate. The result looks fluid and almost dreamlike, which is why high frame rates are popular for sports, nature, and impact moments.

Not all high frame rate modes are equal. Some cameras drop resolution when they reach very high rates, while others use heavy crop or suffer from rolling shutter distortion. The quality of slow motion depends not only on the frame rate but on how the sensor reads out each frame. For a camera that balances these factors well, check our best video cameras guide.

Common slow motion frame rates

The most common high frame rates are 60p, 120p, and 240p. Each step roughly doubles the temporal information, giving you more flexibility when you slow the footage. The right choice depends on how much speed you need to show and what kind of camera you are using.

60p is often the entry point. It provides a modest 2x slowdown compared to 30p and is widely available on consumer cameras, including many compacts and phones. It is a good choice for casual slow motion and for shooting action that has moderate speed, like a person walking or a dog jumping.

120p is the sweet spot for serious creators. It allows a 4x slowdown at 30p or a 5x slowdown at 24p, and it is common on mirrorless cameras and action cameras. You can capture fast movements like a splash, a golf swing, or a bird flapping without eating up too much storage.

240p is for dramatic and extreme slow motion. It gives an 8x slowdown at 30p, but it usually requires a bright scene because the sensor needs more light per frame. Many cameras limit 240p to a lower resolution or a cropped sensor area, so you trade detail for speed. If you need extreme slow motion in a compact package, consider an action camera.

Sensor readout and rolling shutter

When a camera records high frame rates, the sensor must capture, read, and process image data quickly. Most cameras use a rolling shutter, which reads the sensor line by line from top to bottom. If the readout speed is slow, fast motion can distort into diagonal or wavy lines. This distortion is more visible at high frame rates because you are capturing quicker action. See our rolling shutter sensor readout article for a deeper dive.

Some cameras use a fast readout by cropping the sensor or by binning pixels. A cropped readout uses only a central portion of the sensor, which shortens the distance the readout must travel and reduces the rolling shutter effect. The tradeoff is a narrower field of view and sometimes lower resolution. Other cameras use a global shutter, which reads the entire sensor at once, eliminating rolling shutter distortion entirely.

When you compare cameras for slow motion, check the readout speed specification and whether the high frame rate mode crops the sensor. A camera with a slow readout may produce jelly-like artifacts, even if the frame rate is high. The best slow motion cameras combine a high frame rate with a readout that can keep up with the sensor's data output.

Choosing a frame rate

Start by deciding how slow you want the final motion to be. If you need a gentle slowdown, 60p is often enough and lets you keep higher resolution and longer recording times. If you want a dramatic effect, 120p or 240p is a better fit, but you must check whether the camera imposes limitations.

Also think about your delivery timeline. If you are editing at 24p, a 120p clip gives you a 5x slowdown, while 60p gives you 2.5x. If you are editing at 30p, the math changes. Many editors work in 24p for a cinematic look, but some use 30p for sports or online content. Choose a frame rate that divides evenly into your timeline to avoid micro-stutter.

Storage and battery life are practical concerns. High frame rates generate more data, so you need a faster memory card and more capacity. A 240p clip might fill a card in minutes, and the camera may overheat after extended recording. For most users, 120p offers the best balance between slowdown and file size.

Finally, consider the amount of light. At high frame rates, the shutter speed must be fast to avoid motion blur, typically at least double the frame rate. That means 120p often uses a 1/250s shutter, and 240p requires 1/500s or faster. In dim conditions, you may need to raise ISO, which adds noise. A bright outdoor scene is the best environment for extreme slow motion. For a camera that handles this well, browse our best 4K cameras selection.

Camera features that matter for slow motion

Look for a camera that lists its high frame rate mode with actual resolution. Some cameras shoot 4K only up to 60p, then drop to 1080p for 120p or 240p. If you need clear detail in slow motion, check whether the mode retains enough resolution for your output. Many mirrorless cameras offer 4K at 120p, but the implementation varies.

The buffer and bitrate also matter. High frame rate video is often compressed heavily to keep file sizes manageable. A high bitrate preserves more detail and reduces artifacts, but it requires a fast card. A camera with a small buffer may stop recording after a few seconds, which is fine for short clips but not for continuous action.

Image stabilization is another consideration. Handheld slow motion can look shaky, and some cameras use electronic stabilization that works with high frame rates. However, stabilization can crop the image or interfere with the sensor readout. For the cleanest results, use a tripod or a gimbal, especially at very high rates. An action camera often has built-in stabilization tuned for this.

What to pick for your use

Questions

Does a higher frame rate always mean better slow motion?

Not always. A higher frame rate gives you more slowdown, but the camera may reduce resolution or crop the sensor. A 120p clip at full 4K often looks better than a 240p clip at 1080p with a heavy crop. Check the actual specs before choosing. See our video frame rate guide for more context.

What is the best frame rate for slow motion on social media?

For most social platforms, 30p is the common playback rate, so 120p gives a 4x slowdown and 60p gives 2x. 60p is a safe default if you want a subtle effect, while 120p provides more creative flexibility without huge files.

Why does my slow motion look jittery?

Jitter often comes from a mismatch between the frame rate and your timeline. If you record at 60p and edit on a 24p timeline, you get a non-integer slowdown (2.5x), which can cause uneven motion. Use a frame rate that divides evenly into your timeline, like 120p on a 30p timeline.

Can I shoot slow motion in low light?

Yes, but you need a fast lens and a higher ISO. High frame rates require fast shutter speeds, so you may need to push the ISO, which introduces noise. A camera with a large sensor and good low-light performance is better for indoor slow motion.
