It is likely that some music videos from the 80s were recorded on reel-to-reel tapes. Reel-to-reel tape recording was a popular format for audio recording in the 70s and 80s, particularly among audiophiles. It offered high fidelity and a wide dynamic range, but the tapes were cumbersome and not portable. Reel-to-reel tapes were also used in recording studios for mastering and mixing music. However, it is also possible that some music videos from the 80s were recorded using other formats, such as Betamax or VHS.
