The home video formats nobody can play any more

These are listed in the order worth acting on, which with obsolete home video formats is not the order they are usually presented in.

The tapes degrade and so do the machines

Magnetic tape suffers binder breakdown, oxide shedding and mould, particularly in warm, damp storage such as lofts and garages. Playback machines contain rubber belts, pinch rollers and precision heads, all of which perish or wear and are no longer manufactured. The scarce resource is therefore working hardware rather than the tapes themselves.

That scarcity increases every year while the tapes get worse, which is a bad combination.

Camcorder formats multiplied and died fast

Domestic video passed through a long sequence of incompatible tape and disc formats over roughly two decades. Each promised improvement and each was superseded, leaving households with several boxes of mutually unplayable media.

In truth, some formats were commercially marginal even when current, so surviving playback equipment for them is genuinely rare. Format competition served the manufacturers and left the customers with an archive problem.

Discs are not safer

Recordable discs were widely believed to be permanent and in practice suffer dye degradation, delamination and disc rot at highly variable rates. Quality varied enormously between manufacturers and batches, and there is no reliable way to identify a failing disc before reading it.

Optical drives are also disappearing from consumer computers, which adds a hardware problem to a media problem. The generation that transferred tapes to disc for safekeeping frequently made things worse.

Digitisation is straightforward and time-consuming

Transfer requires playing the tape in real time through a capture device, so an hour of footage takes an hour, plus handling. Commercial services exist and vary considerably in quality, particularly in how they handle damaged tape and what format they deliver. The output should be a common, well-supported format stored in more than one place, not a proprietary container on a single drive.

Doing it badly once is much better than doing it perfectly never.

The content is more valuable than it looks

Home video captures ordinary rooms, speech patterns, clothing, streets and pets, which is exactly the material institutional archives lack. Several archives now actively collect domestic footage for this reason, having previously ignored it entirely.

For a while, it is also the only recording of the voices of many people, which families discover at the worst possible moment. Value here is not correlated with production quality in any way at all.

Broadcast archives faced this first

Broadcasters lost significant amounts of early material through tape reuse, poor storage and deliberate disposal when storage was expensive. Recovery efforts have relied heavily on off-air recordings held by private individuals and on copies sent abroad.

In truth, the lesson taken by professional archives — migrate early, keep multiple copies, prefer open formats — applies directly to households. Institutions learned this expensively and the advice is free.

Everything above, in order of what to do first

The takeaway

The tapes will probably outlast the machines, which means the deadline is not the decay of the recording but the last working player.

What replaced it works. That is not the same as it being nothing.
