Can someone please explain to me why my camera reacts this way to these LEDs? It only shows up while taking video or in live view. The red one looks like it's caused by infrared and the blue, I dunno. Like, why vertical lines? Is that the arrangement of the cells on the sensor or something?

Congratulations. You've discovered lens flare which is dependent on quality of optics and sensor and how it scatters the light.

Oops forgot to click the picture, idiot.

LEDs operate by rapidly flashing lights (at around the frequency of the current running through them). Like a television or computer screen, cameras can pick up the blinking since your camera's fps is off the LED's frequency causing interference. Don't quote me on this, I don't remember my Electrical Engineering classes too well.

Actual camera designer here. Nice smear you've got going there. No IR or anything (LEDs are nearly monochromatic), just excess photocharges flooding the transport registers of your interline CCD. Since the usual transport direction is from top to bottom, you get vertical lines. Gotta remember the trick with the flashing LED though, could come in handy when measuring smear resistance.

Same reason why I sometimes get crazy tearing when there's omgedgecontrast due to the sun behind someone's shoulder or something?

If a LED is connected to alternating current, it'll flash at the frequency of the current (since D=Diode=power only goes one way through it). But LEDs are never connected directly to alternating current, they're connected to direct current, so always on.

(You can test this yourself: Take a picture of an LED with a shutter speed greater than 1/60th of a second)

Hey, that's an FD mount lens back there.

this also happens with other light sources too ive noticed so be careful what your pointing your camera at...
