The video shows a close-up of a tree trunk with a red substance on it. The substance appears to be dripping down the trunk, and there are ants crawling on it. The trunk has a rough texture, and the red substance contrasts with the brown color of the bark. The ants are small and black, and they are moving quickly over the substance. The video is shot in natural light, and the background is blurred, focusing the viewer's attention on the tree trunk and the ants.
