Looks kind of bad; not enough contrast where it's needed. I started painstakingly increasing the brightness in one area of each frame, which helped. If only I had software which "tracked" like I saw on the Lord of the Rings behind the scenes footage. I'll still try stabilizing the left video.

It's attached, if you can make out what's what in the gray mess.

I may just have to simplify things, but the lack of contrast still gets me.
