Short version: SVPflow is a successor to MVTools2, providing more speed and more quality. Now available for Windows/Linux/Mac in both 32 and 64-bit versions.

Long story
With all respect to Fizick MVTools is old and there’s almost no progress (except for bug fixes) for several years now. Obviously MVTools isn’t perfect so someone should do something with it And there comes another problem: MVTools is big and fat. There’re tons of dead, commented and copy-pasted code in it. For example all “client” functions (MFlow, MFlowFps, MBlockFps, …) are identical in at least 50% of code which is bad for further development.
And there’s SVP project that started in 2008 on biggest Russian IT forum (iXBT.com). Main goal was to provide some user-friendly controls over all that MVTools-based scripts inside ffdshow for real-time smooth video playback. They’ve experimented with scripts, tuned GUI and so on.
At some time I’ve noticed that MVTools performance is too low on AMD CPU’s, so I’ve made a patch that increased MFlow / MFlowFps speeds up to 50% on all Athlons/Phenoms. That was the beginning – SVP 2.0
The second step was creating MSmoothFps function that incorporates all “client” MVTools function in one with GPU accelerated rendering via OpenCL and some more stuff and it was SVP 3.0. The output of this function was per-pixel the same as output of original MFlowXXX. In latter versions we’ve made some speed optimizations (20-50%) in motion vectors search.
But all of that was only a warming-up before the real job – to give MVTools a second life.


So, SVPflow consists of two parts: GPLed motion vectors search and closed-source frame rendering.

Disclaimer.
SVPflow isn’t a complete replacement for MVTools cause it’s missing most of additional functions. As of now the main goal of project is to provide fast and high quality real-time video conversion, so all functions unnecessary for this task was cut off and sources were cleared and refactored.

Also there’re a lot of new features added and I could tell about them if someone is interested in
