Smooth slowmo in sony vegas

[Ltab-]

Does anyone has some tip for me to make a pretty smooth and flow slowmo? like when I make the clip longer using CTRL and making the clip longer, it gets slowmo, but it's pretty laggy and doesn't really looks well, for example


THE SMELL OF YOUNG GIRLS IS NEARBY


Last stunt

I know it's twixtor or something, but is it for AAE or SV, is it a plugin or some configuration? you know, that kind of stuff, also I'd appreciate other kind of plugins or whatever that twixtor is :>

Thanks

Twixtor is an OFX plugin. I might still have it somewhere, get on MSN. Oh, don't worry, it's for both AE and SV.

Thanks :> and it will be better if you upload it to somewhere else, I'm in another city atm until midnight.
