These are stills (rotated 90° clockwise) from a video showing the ovipositor coming out of its sheath and going into a piece of wood for egg laying. I have more angles of this wasp (or a similar one) that I saw in the same location yesterday: https://www.inaturalist.org/observations/56695516
The location of this egg laying is on the side of a piece of wood just centimeters from where I made this observation three months earlier: https://www.inaturalist.org/observations/46284368
