Twixtor is a powerful program for Windows that allows you to change the frame rate of a video clip, giving you the ability to obtain impressive visuals. The utility comes in the form of a dedicated plugin that integrates seamlessly within various software distributions such as Adobe Premiere, Avid Media, SONY Vegas Pro or Vegas Movie Studio.

Functionality

The application is a convenient solution when you want to add slow-motion or acceleration effects to your videos. The main advantage of using this plugin is the increased accuracy which enables you to track objects farther. What is more, the output exhibits fewer artifacts if there are items that intersect with the current frame. Due to the high level of precision, objects are not torn or stretched as they appear or move out of the scene.

Performance

Regardless of the action you want to perform, be it speeding up or slowing down image sequences, the tool manages to preserve the quality of the original multimedia files. Basically, it creates new frames after interpolating frames of the initial video stream while tracking the motion for each individual pixel. Thus you have the possibility to achieve unparalleled image detail.
