I'm working with Boris Graffitti 5.3 in Vegas 8 pro. When I select an event of e.g. 10 seconds in Vegas and then open Graffitti via event FX, it always shows a timeline in grafitti of only 1 second and 5 frames, but never the length of the event in Vegas.
What am I doing wrong?
You're not doing anything wrong - it's just that Vegas doesn't hand off the length of the event to Graffiti so you'll have to make that change in Graffiti manually. To do that just enter the correct length in the Time field in the Graffiti Timeline WIndow.
