This is most likely flicker/banding from your indoor lighting, not the camera sensor or lens.

Many ceiling lights (fluorescent, LED, some sodium or other mains-powered lights) don’t emit constant light. Their brightness and even color can change rapidly with the AC power cycle. At 1/200s, especially in burst mode, each frame may capture a different phase of that cycle, causing horizontal bands and a yellow/green color shift in part of the image.

Your settings also forced the camera into a difficult situation: f/13–f/14 indoors is very small for action, so ISO had to go extremely high. For moving subjects indoors with a 50mm f/1.8, open the lens much wider if possible.

To reduce the problem:

• use a wider aperture instead of f/13–f/14
• try shutter speeds matched to mains frequency, such as 1/100 or 1/50 (or 1/120 or 1/60 depending on your region)
• avoid problematic room lighting if possible
• use flash or continuous lights designed for photography
• if your camera supports anti-flicker shooting, enable it

So the “random” band position is really the light flicker interacting with your shutter timing.
