Interpolation

What it is

Interpolation is the process of generating intermediate frames between two existing ones to create smoother motion. It's often powered by algorithms or AI in editing and VFX tools.

Why it's important

It allows footage shot at one frame rate to be played back at another (e.g., converting 24fps to 60fps). It’s also used for slow motion, smooth time warps or motion ramps, upscaling, and VR/AR experiences.

When/how to use

Use interpolation when retiming footage or creating slow-mo from standard frame rates. Be mindful—poor interpolation can result in visual artifacts like ghosting or warping.

Best Practices

Use when natural – Apply interpolation to enhance smoothness, but avoid overuse that creates unnatural artifacts.
Choose the right method – Optical flow, frame blending, or AI-based interpolation each serve different needs—match the method to the project.
Test across outputs – Review on multiple devices to ensure interpolated results look seamless in final playback.
