Using the same technique as before, I've started to make panoramas of Halo2. This time with a slightly higher resolution (2400x360) but still a bit fuzzy (using a cheap TVtuner to capture).
In addition to the software used I've modified a controller to automatically turn for me, which makes the creation process much more relaxed as I don't have to cramp my thumb to hold the stick in the same position for a minute or two.
Another factor that enables odd angle panoramas (in Single Player) is the Blind Skull that you can find in outskirts; which removes the hud, making it possible to use the center pixel collumn when generating the panoramas avoiding a leaning image.
There's a flash tab for each of the thumbnails with two different choices. Large or small. The L opens a 720x360 window with a flash viewer for that panorama, and the S opens a window half that size. In the viewer just click and hold your left mouse button anywhere, and then drag to the sides.
