I needed a special effect sequence for a future feature. i.e. a cat changing into a woman. Here is the rough screen test of the effect accomplished using Vegas: (runs 22 seconds).
Technical: Accomplished using fixed camera shots of both subjects, duplicate vidio tracks of subject material, and third lower track.
Using the 'Fade Through Transparent' dissolve on the top track, a common fade through on the duplicate second track, with 'Intense Light Rays' plug-in on trailing second track woman shot. Also reduced that shot's Opacity to 75% allowing animated rays on bottom track to leak through the 3.27 second transition window.
This was just a proof-of-concept using the cheap camera, an un-lit set and one fixed subject. For the actual feature I will be replacing the toy with a live cat (fun city - smile).
