when you say echo, can you unpack that a little? do you mean simply a repeat or two of the twirl mixed with the original twirl, slightly delayed? Or do you mean a multi-repeat slightly offset, a la Jackson 5 doing "Blame it on the Boogie"?
I'm not sure, Matt. I believe it's the first one. Ultiimately, what I want
to show is the twirl and then a slight "drag" of the dress for 1 or 2
seconds were the original footage moved and the echo is following it. I hope
this makes sense. Thanks
take the clip of the dress twirling and set that down on Video 1.
take the same clip from the source monitor and plonk it on Video 2, but slightly later in time... say .5 to 1 second.
pull the opacity of the Video 2 clip down till you get a mix you like. dissolve into and out of the Video 2 clip.
maybe add some time re-mapping to the ending portion of both clips to up the "romance" factor??
go to Video Effects > Time > Echo, and tweak the parameters to get what you want (you'll have to ramp up the default time considerably)!!
That the effect you're after??
