RE:Vision Effects is now shipping Twixtor 4.5 for Apple Final Cut Pro (FCP) in an FxPlug version, which is Final Cut Pro's native effects plug-in architecture.

Twixtor enables users to speed up, slow down image sequences. Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence employing RE:Vision Effects' Academy Award-winning technology that calculates motion for each individual pixel.

The After Effects-compatible version continues to work within Final Cut Pro. What are the differences? The FxPlug version can process images in 10-bit YUV (and greater bit depths, when supported). The After Effects-compatible version only works in 8-bits per channel within FCP, but can also run in After Effects, Combustion and Premiere Pro. RE:Vision

Effects says that 8-bit processing within the FxPlug version is significantly faster than the After Effects-compatible version, but 10 bit or full precision YUV processing takes longer than the 8-bit processing in order to take full advantage of the extra bit depth. The FxPlug version runs within FCP 6.0.3 and up, while the After Effects-compatible version will run in any version of FCP from version 4.0 and up.

The company says that the FxPlug version is the better alternative when using Twixtor within FCP because it is Apple's native effects plugin format. Apple is continuing to add new features for FxPlug plugins, and as such there are greater future opportunities for Twixtor within FCP in the FxPlug version. Additionally, it is hoped to include Twixtor support for Motion and Final Cut Express in a future release of the FxPlug version.

The Regular version of the FxPlug or After Effects-compatible plug-in costs US$329.99 (around £167), with the Pro version costing $595 (£302). Upgrades from Regular to Pro cost $265 (£134).

Owners of either Regular version can get the other for $99.95 (£51). To do the same with the Pro version costs $179.95 (£91).
