RE:Vision Effects Twixtor for Fusion - featured

Twixtor is the essential tool for slowing down, and speeding up, or modifying the frame rate of video footage.

Twixtor takes advantage of proprietary tracking technology to accurately accelerate, decelerate or alter the frame rate of your video or image sequence. Work with precision while effectively tracking elements farther, and with less stretching and tearing when objects are crossing your subject or leaves the frame.


Twixtor enables you to speed up, slow down or frame rate convert* your image sequences with visually stunning results. In order to achieve its unparalleled image quality, Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence... employing RE:Vision's proprietary tracking technology that calculates motion for each individual pixel.

*Frame rate conversion fully supported with After Effects and combustion only. Frame rate conversions can often be accomplished in other applications by writing out image sequences and reading them back in with a different frame rate setting.

Twixtor Features

World class motion estimation

Twixtor is more accurate and exhibits fewer artifacts when there are objects crossing in the scene. This means less tearing and stretching of objects as they cross or go out of the frame.

No sweat

Retime using a single speed setting. Option to control retiming on frame-by-frame basis is always available!

Visually stunning results

In order to achieve unparalleled image quality we developed proprietary tracking technology that calculates motion for each individual pixel, enabling Twixtor to synthesize unique new frames by warping and interpolating frames of the original sequence.

Feature Specs

  • Time Warp - Warping and interpolation of frames to "time warp" input footage.
  • Speed Changes - Retime a sequence made possible using a single speed parameter.
  • Frame by Frame - Keyframable retiming for complete control on a frame by frame basis.
  • Motion Blur - Contains an option to add or remove motion motion blur, as appropriate.
  • Frame Rate Conversion - Frame rate conversions made easy (Important Note: frame rate conversions are supported only from within After Effects and Combustion.)
  • Enhance Dark Imagery - Option to automatically enhance dark imagery or imagery with poorly defined edges. In many cases, footage that was difficult to track becomes much more well-behaved upon retiming.
  • Cuts Marking - Support for marking material so that Twixtor does not motion-interpolate across a cut.
  • Interlaced Processing - Smart processing of interlaced material.
  • Object Separation - Support for foreground and background separation using a specified matte. Twixtor then tracks each layer separately for improved results.
  • Track Point Guidance - Up to 12 user-defined points can be specified to help guide Twixtor's motion estimation. By using the tracking points you can explicitly tell Twixtor where a pixel moves from one frame to the next in order to guide Twixtor's calculation of motion vectors.
  • Spline Guidance - When Twixtor exhibits tracking problems, you can guide Twixtor by simply creating and animating shapes to show Twixtor where objects are actually moving. Interactive feature registration is directed by using the host program's splines.
  • Motion Vector Import - Give Twixtor motion vectors generated elsewhere (like from a 3D system) to time remap footage, including adding motion-interpolated fields to otherwise progressive material.
  • Motion Vectors Export - Ability to output the motion vectors that Twixtor generates internally. This powerful feature comes with visual debugging modes to more intuitively assess and tune the quality of the motion estimation. The motion vectors can then be used elsewhere in the pipeline.
  • GPU accelerated - This product is GPU accelerated.

Updates in Version 6.0

Speedups up to 3x on GPUs when using Twixtor, already known for their speed, have been measured over running in CPU mode. Speedups of this magnitude are usually seen with higher end cards and larger image sizes. Note that most currently-sold GPUs will provide customers with needed acceleration, including many mobile GPUs for laptops. Of course, the total speedup end-users will see will vary once application overhead is taken into account: this includes disk I/O, internal host buffering schemes, bandwidth of PCIe bus, codec used for footage, etc.

What's new in Version 6.3 | November 1, 2016

  • Added an update checker for future version updating. The update check runs on the local machine, and must be manually run.
  • Fixes potential crashing bug when using images that have negative color values.

What's new in Version 6.2 | June 3, 2016

  • Adds Fusion Studio 8.0 support
  • Adds Macintosh support

What's new in version 6.1.2? Posted September 24, 2014:

  • Better GPU support with fewer failed GPU renders.
  • Fixed a crashing bug.
  • Fusion Studio 7, build 1420 and up
  • Fusion Studio 8, v8.2.1 and up
  • Fusion Studio 9, v9.0 and up
