Before asking for the video's source, make an effort to find it yourself by running a search on the webm's title metadata. You'd be surprised what can turn up if you simply append "kpop" to the search query.
Title metadata may be read using 4chan X (https://ccd0.github.io/4chan-x/
) inline or by downloading the file and using a video player like vlc (press ctrl+i) or mpc-hc (press ctrl+3).
Conversely, for those making webms, include the video source within the title metadata to help those interested and for the information to stay with the webm if it's ever reposted.
e.g. ffmpeg -i input.webm -c copy -metadata title="Your Title" output.webm
Try to not post webms that were just in the previous thread, unless requested.
