I am looking at using a setup of multiple webcams (5+) to recreate the bullet time effect. However, I have no idea how to simultaneously capture photos from all the webcams hooked up to my computer. How do I do this? I can't have any delay between the pictures; they all have to be taken at the exact same time.
Couldn't you just record videos and synchronize them based on sound or something? You could save frames as images with something like
ffmpeg -i input.mov -r 5 %d.png.
I'm not sure this will do everything you need, but SecuritySpy is able to capture video from half a dozen cameras or more simultaneously.
