Watch as this mesmerising experience threatens to convince you that you just discovered time travel and multiple dimensions!
The feedback loop generated here is a process where the delay in processing the frames captured by the camera and then being recaptured result in a cascading effect as seen above.
When it was first discovered in the mid-1950’s it was considered a nuisance and videographers caught accidentally capturing their own output monitors on camera were chastised. This was also possibly due to the fact that on the analog cameras they used back then, this effect could actually cause damage. (It won’t with your digital camera, relax)
The effect was later used artistically, and became a normal feature in many pop culture classics. Here is a list of early adopters and famous uses!
An example is Queen’s music video for “Bohemian Rhapsody” (1975). The effect (in this simple case) can be compared to looking at oneself between two mirrors.
Other videos that use variations of video feedback include:
