High-fidelity temporal manipulation. Create dramatic slow-motion or rapid time-lapse effects with browser-first processing.
All video manipulation occurs locally. No uploads, no waiting, and no privacy concerns.
MP4, WebM, MOV supported
Adjust from 0.25x to 4x
Video Speed Pro provides surgical precision over playback rate. From super slow-motion at 0.25x to rapid time-lapse at 4x, you have complete control over the temporal dimension of your video content, allowing for dramatic creative effects or practical viewing speed adjustments.
Our tool uses advanced frame-by-frame rendering via the Canvas API to create a new video at the specified speed. This ensures that the output video has freshly encoded timestamps, making it compatible with all video players and social media platforms without sync issues.
Speed-adjusted videos are rendered without audio by default to avoid pitch distortion. All processing occurs in your browser's sandbox, ensuring that your personal videos, business recordings, or sensitive content never leaves your device. This is zero-upload, local-first engineering.
Changing the speed of a video is a fundamental technique in video production. Slow motion can add drama and emphasis to key moments, while fast forward can condense long processes into digestible time-lapses. Zrubix Video Speed Pro gives you these professional capabilities directly in your browser, without the need for complex desktop software like Premiere Pro or DaVinci Resolve.
Why is browser-based speed adjustment superior for quick tasks? Not everyone has access to or the expertise for enterprise-grade editing suites. Our tool is designed for rapid iteration—upload, select speed, and export. The entire process takes seconds, making it ideal for marketers creating social media content, educators adjusting lecture recordings, or anyone who needs to quickly modify video pacing.
Under the hood, Zrubix leverages the native `playbackRate` property of the HTML Video element to play your source video at the specified speed. Simultaneously, we capture each frame onto a Canvas element and pipe that stream into the MediaRecorder API. This creates a brand new video file where each frame corresponds to the adjusted time, ensuring the output file is temporally correct and universally playable.
This method is distinct from simply changing playback speed in a video player, which is a temporary effect. Our output is a new, baked-in video file that will play at the new speed on any device, no matter what player is used. This is essential for content destined for upload to platforms like YouTube, TikTok, or Instagram, which require files with consistent framing.
Video Speed Pro is a key component of the Zrubix video toolkit. After adjusting your video's pace, you might want to compress the file for easier sharing using our Video Compressor, or convert a short clip to a GIF with MP4 to GIF. Our suite provides an end-to-end workflow for video content optimization, all within your browser, all without a single server upload.
Experience the future of video editing with the surgical precision and professional aesthetic that only Zrubix can provide. Manipulate time, create impact, and export with confidence.
