Is it possible to keyframe a linear wipe effect in Vegas 6.0 to control the speed of the effect at different times .( first 5 second, wipe fast, then pause for 1 seconds, and finally wipe the rest slowly to sync with the narration)
Thanks in advance for any help I can get
Try right clicking the transition and choose Insert Transition Progress envelope, if you are talking about controlling the behavior of a single transition.
However, it sounds like you want automated transitions throughout a project. I know of no way to do that.
After you insert the envelope transition progress envelope, double-click on the line you see to add nodes (points). Drag these up/down to alter the speed of the transition.
