There's a lost tornado video which my friend discovered in mid-2021 and he told me the details of the video in the messenger that the footage was taken during the Rancaekek, Bandung tornado of April 2011. He described the footage with the footage being low quality but clear and it was taken in a housing region, the footage shows the tornado after striking the Junior High School (SMP4). The wall cloud in the footage was shown to become widened but the funnel narrows while still remains strong (it is likely that other damage was recorded outside of the SMP4).
Another lost tornado video which i found while watching Raging Planet - Tornado documentary, the footage was said to be taken in Yokohama, Japan on April 1997. The video shows a narrow but likely intense sub-vortex passing between some pylon poles.
