Blender has recently released their new 2.75 version, with a few changes in the Video Sequence Editor. All the Velvets tested ok for this new version, with minor updates.
The Space_Sequencer is pretty much specific to each Blender version, so you should always update it along with the program. Velvet Goldmine had a minor change in one of its shortcuts: now, to toggle between different Resolution Percentages, use Ctrl+Alt+R instead of the former Ctrl+Alt+Shift+R. Also, both Velvet Revolver and Blue Velvet have been tested with FFmpeg 2.7.1 and the new Ardour 4.1.0 (for the latter).
