RE:Vision Effects (http://www.revisionfx.com) has released ReelSmart Motion Blur version 5 and Twixtor version 6 with GPU support for eyeon Fusion .
Speedups up to 3x on GPUs when using RSMB and Twixtor, already known for their speed, have been measured over running in CPU mode, according to the folks at RE:Vision Effects. Twixtor creates slow motion shots without the cost of renting a high speed camera. ReelSmart Motion Blur (RSMB) automatically adds more natural-looking motion blur to a sequence.
RE:Vision Effects plug-ins are available for Sony Vegas Pro, Adobe After Effects, Eyeon Fusion, Apple Final Cut Pro and Motion, The Foundry’s Nuke, Adobe Premiere Pro, Autodesk 3ds Max/Maya Composite, Avid editing systems, Autodesk Systems (Sparks), Autodesk SoftImage, Quantel genQ and others.
