AI-Driven Time Remapping

SpeedX is a cutting-edge time remapping plugin, leveraging AI technology to intelligently interpolate additional images between frames for seamless video acceleration and deceleration.

Check GPU Requirements and try a demo before purchasing SpeedX

Note: The performance of SpeedX is highly dependent on GPU, and some GPU cards are not supported. Please see the System Requirements tab for GPU details. Also, PLEASE TRY a DEMO of SpeedX before purchasing.

The plugin adopts the sophisticated AI-based optical flow method to calculate the object motions in the video sequence. Moreover, thanks to the intelligent AI technology, SpeedX can perceive the occlusion around the motion boundaries. And then it adaptively fuses the image pixels under the guidance of accurate pixel-based optical flow and occlusion information, therefore, generates high quality and more realistic intermediate frames.

SpeedX is a professional and affordable tool for time remapping, always with visually stunning results. It is ideal for video frame rate conversion, super slow motion, speed change, variable reverse playback and more creative video effects.

Moreover, SpeedX plugin is GPU accelerated for Adobe After Effects and Adobe Premiere Pro, and available for Mac and Windows.

NOTE: The performance is highly dependent on GPU, and some old GPU cards (before 2012) are not supported. Please TRY it before purchase.


Simple and user friendly controls.

Two retiming modes: Speed Ratio and Frame Number.
Four interpolation modes: Smooth, Sharp, Nearest, and Blend. Smooth and Sharp modes are with AI technology.

Frame interpolation

Frame interpolation with visually stunning results, ideally for time remapping applications.

Accurate motion vector

Accurate motion vector for each pixel is obtained using occlusion-aware optical flow method. With the accurate motion vectors, SpeedX adaptively fuses the image pixels to generate high quality and realistic intermediate frames.

Intelligent AI technology

Intelligent AI technology analyzes the pixels of large amount of clips and preceives the occlusion around the motion boundaries. SpeedX can handle large motion and occlusion better than the traditional technology, therefore it improves the interpolated image quality.

SpeedX utilizes the GPU resource for computation with Vulkan API. Most of the issues that users encounter are related to the GPU configuration. It is recommended to upgrade to the latest GPU driver. The GPU should support Vulkan 1.1. If it is a discrete GPU or M1/2 chip, please contact support for further assistance.


  • Driver for GPU must support Vulkan 1.1. To check if it supports Vulkan:
  • Note: Intel integrated GPUs are not supported.
  • GPU with 3 GB memory is supported for HD footage. Larger GPU memory is recommended for UHD or higher resolution.
