General Rolling Shutter.

So, everyone should know what the rolling shutter is, the "jello effect."

I have a question about it. Its just bugging me for some reason.

When you pan quickly L/R, the image is slanted in the direction you are turning the camera - because it basically scans the image from top to bottom.

What happens if you tilt the camera quickly up & down. Shouldn't that squish and compress the image when tilting quickly?

Yep. One way it will squish/compress, and the other way it will stretch the image out.

huh.... I had a feeling.
Its not really noticeable when you tilt though. I never heard a complain about it either. Must be because panning is more used than tilting, bur still.

If you have your video on the big screen, you'd you notice it then?

Panning is far more common than tilting, and panning at high speeds is much more common than tilting at high speeds.

If you want to see some wackiness, get a fujinon backfocus chart, and tilt that camera at a fast rate up and down... it's super-rubbery and stretchy and wild.
