Professional Video Speed Control

Precise Speed Control from 0.50x to 4x with fine 0.05 Increments

Transform your video playback speed with professional-grade precision using our engine that supports incremental adjustments from half-speed to quadruple-speed. The granular 0.05x step control in "Speed Mode" allows content creators to fine-tune their footage for optimal viewing experience, whether you're creating educational content that needs careful pacing or dynamic social media posts that demand attention-grabbing speed.

Set Custom Target Duration

Our innovative "Duration Mode" feature lets you specify the exact final length of your processed video, eliminating guesswork from your content creation workflow. Choose from convenient predefined duration options for common social media formats, or input precise custom timing to meet specific platform requirements, presentation schedules, or content strategy goals with mathematical accuracy.
