Intelligently slow down or speed up your image sequences with visually stunning results.
Twixtor in Action

Twixtor 360 Demo
Twixtor uses optical flow tracking on 360 footage taking into account the connectedness of the left and right sides of the 360 video, as well as the top and bottom.

"Twixtor represents a new touchstone in retiming. The difference in accuracy means that retiming artifacts are either drastically reduced or disappear on the hardest to retime footage. "
"amazing" and "a must-have for any toolkit."
"I've tried other solutions - including Pixel Motion and Timewarp in After Effects 7 - and I have to say that Twixtor still consistently gives me the smoothest speed-shifted footage with the least amount of sweat, hands-down."
Read the review"I highly recommend this plugin to those seeking absolute superiority in time frame manipulation."
Read the review"it's the best plug-in method for creating speed changes, slow-motion effects, and frame-rate conversions."
"If you regularly find yourself stretching or shrinking footage to fit a target duration, or creating extreme speed control special effects, this is a plugin that you'll find invaluable."
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.
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.
Retime 360 video
Twixtor tracks 360 footage and retimes properly taking into account the connectedness of the edges of the sides as well as the top and bottom.
Motion Blur
Contains an option to add or remove motion motion blur, as appropriate.
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.
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
