Maybe the video log shots could just be shrunk to fit in the 2.39:1 frame? As in, black bars on the sides (which, I suppose, would mean windowboxing them, as it'd be black bars all around)? I don't think it'd be distracting, and it'd make the video log shots feel different than the rest of the film, which they currently don't.

That's a good idea - just tried it out and it works well, so I've gone and done that for all of Jake's Vlog shots.

Oddly enough, the camera shots from the new "Drums of War" segment (where the soldier is sending video to Quaritch on the Navi's attack of the bulldozer) doesn't suffer from this same problem and it's overlay graphics work perfectly with the 2.35:1 matte.
