Agree with Wes. It was a Monsterquest ep. They basically overturned the old adage that the camera never lies.  In fact, because a video is essentially a series of still photographs and however long the shutter is open for on a given still photo can result in a blurry photo if the object was moving too fast.  In this case, they did a side-by-side with a slow motion camera (1000 frames per second, or something) and you could clearly see the insect in that camera, while the camera next to it just as clearly showed a "rod" because it wasn't fast enough to capture the insect accurately.
