Speed ramping is an editing technique that smoothly transitions a clip between different playback speeds within a single continuous shot, accelerating or decelerating action over a specified duration rather than cutting between footage captured at different rates. Rather than jumping abruptly from full speed to slow motion, a speed ramp eases fluidly through the transition, creating a dynamic, flowing effect that draws attention to a specific moment by dramatically slowing it within an otherwise normal or accelerated sequence.

The technique became widely used in action and sports content, music videos, and commercial production because of its ability to create moments of visual drama and emphasis without a cut. A common application ramps from normal speed into extreme slow motion at the peak of an action - a jump, a collision, a key moment - then accelerates back out, giving the highlight moment maximum visual weight. The effect is achieved in post-production using time-remapping tools available in all professional video editing software, which allow editors to draw a variable speed curve across a clip's timeline. The smoothness of the transition depends on the original frame rate of the footage - higher frame rates captured during shooting give more frames to work with during slow motion sections, producing smoother results.

In AI video generation workflows, speed ramping is applied in post-production rather than during generation itself. Generating clips at the highest available frame rate provides the most flexibility for speed ramping in the edit, as more source frames means smoother slow motion sections when the speed is reduced at the ramp point.
