RealViz has announced version 2.0 of its ReTimer video speed effects package. The package uses an accurate warping technique developed by French research lab INRIA to automatically create new frames to slow down or extend video sequences. The same technique can also be used in reverse to speed up or shorten clips. New in version 2.0 is the replacement of the vector grid with computed motion (dense flow) given to individual pixels, which should minimise manual corrections. Support of single channel images has been improved, as has management of rendered sequences. Batch processing is also available in ReTimer 2.0. The selection of editing tools has also been added to. Matching between frames can now be performed manually, and mattes for moving objects can be used. ReTimer runs on Windows NT, Irix and Linux – and will cost around £1,200. It will be released at the NAB show on April 10.
