Hello, I am an editor of video tutorials. I have a bunch of hours of footage to edit from studio sessions where an artist does a painting demonstration while being filmed simultaneously with two cameras: one capturing his painting, the other capturing his palette.
Is there a plugin that would allow me automatically cut to the palette shot whenever his hand enters the frame, and then cut back to the painting when his hand enters the painting frame? This would save me so much time.
Am a bit late in replying but will just add something to what Neil said. I am also not aware of a plugin that does what you ask and like Neil would say that you'll develop your own ways to be more effcient with repetitive tasks like this. One thing I have learned with anything that is automated is that it is these things are not 100% accurate and so you still need to check it and fix up mistakes. In some cases, that can take as much time as doing the repetitive task yourself.
The key word is "may". When the scene is the same, and only a hand enters or leaves, getting a reliable cut is pretty iffy in my experience. May well be worth doing just to get things started. But ... going down the timeline with playback 3-4 times normal speed, stopping: Ctrl/Cmd-K and resume might not be that much slower. Compared to having to uncut some wrong cuts and add some correct cuts.
true, some plugins let you customize the threshold of pixel change detection or you can crop the image so the object is proportionally large in the frame. this idea probably is only practicable if you have many, many hours of footage as like you said, real life is never perfect.
