We (@rinzo and me) just created this videoclip. The video was already created and longer than you see used in the final video. What we did was registering some music out of the blue, cut the music off, save it, then use ffmpeg to merge the two together, cutting off at the shortest and removing the sound from the original. This results in the clip you see here. The process is almost too simple, and it's intentionally rough, but the result is surprisingly interesting and matches up at so many incidental moments that we think the result is quite worth it!
At the moment a similar music video, this time just merging together an existing video clip and complete song together, are being uploaded to YouTube, too. We think the result is hillarious! If you want to look it up when it is online and processed, it's on the Rinzo & the Hey Hey Panthers channel and is called Rosalie.
