That seems good for live switching, where you do need a queued/next shot, but for non-linear editing there isn't really a "next" shot is there? Just stop at the exact frame and switch the video source...

How about a macro, you go through it once, and it does the changes that you would normally do be hand. The interface would be reminiscent of a traditional video switcher. This is a sample interface layout that I designed: http://i7.tinypic.com/20z73me.png. The right side looks rough, because I started with the traditional "A/B" switch. I changed to a "queued" concept. The idea is that the operator would choose the next source to switch to, and would have the desired transition and transition length selected. When the "Go" button is pushed, the transition is added. The VCR "Rewind" and "Fast Forward" buttons would go to the beginning of the previous transition and forward to the next transition, respectively. The macro would simply make it easier to put in and tweak the transition effects and transparency keyframes. - Jordan On Tue, 2006-07-25 at 02:15 -0400, Dan Streetman wrote: > I do the same thing (edit multi-angle live events) and I have thought > for some time about doing exactly that, a video effect to facilitate > easy editing... > > What I do now is change the project size to twice the camera size > (i.e. to 1400x960) and use each track's projector automation to fake a > live switching setup, i.e. each video track in its part of the 2x2 > layout.
