I’m comparing the Canon 5D’s mechanical shutter for stills with its electronic rolling shutter in video. In high-speed footage of the mechanical shutter, the first curtain moves so exposure travels from the top of the sensor toward the bottom. Because the lens projects an inverted image onto the sensor, that means the bottom of the final image is exposed first.

In rolling-shutter video examples from the 5D series, vertical subjects appear to lean in a way that suggests the top of the recorded image is read first and the bottom last. That would imply the electronic readout scans from top to bottom of the image.

So is the conclusion correct that, on a Canon 5D, the video rolling shutter operates in the opposite image direction from the mechanical shutter used for still photos?
