Interpolating between 4 cameras?

Bag of Douche
Hey guys - I'm looking to achieve an effect where basically 4 cameras are on a rig - I need to take the footage and cut inbetween them to create sort of a "jittery" effect, where the camera is effectively moving around from left to right about 75 degrees, always focused on the talent.

I need this to NOT look like straight cuts - or in other words - I need to interpolate frames inbetween - so I'm wondering what the best way to achieve this would be, to basically tween motion between the keyframes (the 4 cameras)

Thanks guys
 
Well, I would certainly use a morphing plugin of some sort for AE or whatever the compositing software of your choice is.

Now, the more cameras you have the better. If they are too far apart, the morphing between the two shots will look slightly better than a simple dissolve. I have seen some acceptable morphing done for the bullet-time shots when a crew had something like 10 cameras set up for a 90 degree angle. The Beastie Boys music video (link here on the board somewhere) uses that technique but I don't think it looks that good. Also, the short hilarious german film Matrix XP uses the same technique, and to me it looks more like a parody of bullet-time. Which it probably is, considering it's a parody altogether.

Now, I haven't used many morphing plugins for AE, but the morphing engine in Twixtor seems quite advanced. Basically you can use Twixtor for what it wasn't originally designed, by putting your 4 camera shots together (don't forget to match the lighting and colours exactly between the shots), and then applying twixtor to slow them down. That's if you have the bullet-time effect. If you want to simply morph between the shots while there is motion, you could take screen grabs of the last frame of the 1st camera and the first frame of the second, render them side by side in a two-frame clip, then slow down in Twixtor. Then repeat the procedure for the other shots.

That's just what I would do having Twixtor available and knowing its morphing techniques quite well. You can also go further and play with the vector motion masks to tweak the morphing.
