The way I see it happening is that the video is delayed enough so that when the puck actually hits the camera, the video gets encoded[insert correct technical term] wrong - green - for that line. Then we actually get the video of the puck hitting the camera.
- pornel 13y ago> [insert correct technical term] In most MPEG-family video codecs video is split between brightness (luma) and color channels (chroma). This looks like error in one of chroma channels. Image is divided into blocks and average intensity of each block (called DC) is stored as difference from a previous block. It looks like the first block on that line had invalid, out-of-range DC value stored, and this value has been propagated through entire line.

- drakaal 13y agoMore likely caused the sensor to send invalid values for pixels. Still More likely the jostle caused data loss for a while. The green squares don't look to be 16 pixels tall. Hard to tell with the footage, but DC's are typically 16x16 or 8x8 This looks to be a CCD issue not a compression issue especially since the artifacts don't propagate to the next frame, nor cause variations in the sharpness of things in the next frame which would be common if new image data had to be created in whole rather than as a differential from the perfectly noiseless, "broken" frame before.
