The transition rendered very quickly but not the special effect. I went and tried both a transition and a special effect plug-ins. It's at that point that I kind of remembered someone saying that the NewBlue transition plug-ins are slow on his computer. Then, I uninstalled the demo version of NBTP and reinstalled the one for Vegas only. Again, no problems with playback both within the interface and from the Premiere time line. I even created some 3D text and started making it turn and sping. It worked flawlessly: no crash, nice smooth playback, etc. I went into Premiere and started fooling around with NBTP. So I uninstalled it temporarily from Vegas and I installed the demo version for Windows. I must begin by saying that NBTP works fine in Vegas Pro on my computer. I use both Vegas Pro 11 and Premiere Pro CS5.5 but have only ever used the version that came with Vegas. Since BVX3001 wanted to know if anybody had any good experience with NBTP - and reading some of the comments - I got very curious.
