Image stabilization in video lenses is designed to counteract only high-frequency vibrations (shaky hands,) and often only or predominantly in the vertical direction, and not respond much to low-frequency movements, which are usually intentional pans and sometimes tilts.
Image stabilization in still lenses is designed to counteract both high- and low-frequencies in all directions, so the results, depending on the lens and the movement, can be "floaty."
As a side note, at the high end of long telephoto video work, image stabilized lenses are used along with tripod heads that have digital encoders to send data to the lens saying "hey, I'm panning left at this speed, don't try to correct it with IS" and that takes care of the IS creating lag at the start of the pan and spring back at the end.
