I’m sorry but I didnt understand much of that thread, especially the .cs script part.
In all the sony vegas pro programs Ive used in the past ( up to Sony Vegas Pro 9 ) Ive simply highlighted the clips I want, then click Tools – Multicamera – Lay out tracks using Media Timecode.
The clips have been laid out in one track as wanted, then repeat the process with clips from the second camera and all the clips have been laid out in another track.
Generally just needing a slight adjustment and both tracks are in sync.
Sony Vegas Pro 10 will just put one clip in each track there for if trying to lay out 100 clips you end up with 100 tracks
