One of the biggest challenges of capturing 3D footage is getting the footage syncronised. Sure, you can do it in post production. But on most cameras, you have granularity of 1 60th of a second at best. This simply isn't enough for quick motion. Here is part two of the technical talk for synchronising 3D footage.
Here is the fireworks video I mentioned in the episode:
What I was talking about here is how I've placed the pictures above each other so that we can get the best horizontal resolution possible, so here you can see the side effects of doing that. Sadly this isn't the best video to demonstrate how much more awesome the 3D is, because this was long distance and there isn't much 3D to see.
