Not seen this 2008 YT video before, some here might like to observe how re-recording VHS sourced material over 23 generations sees the content disappear and when the distinct stages of loss of detail and features occur .....

Very interesting, but somehow eerie. Glad we've switched to Digital.

The music is oddly fitting. The video is 'fading like a flower' as you go through the generations.

Especially enjoyed the demonstration of this on Channel 4 - using familiar bit of material - from 1991's The Secret Life of Machines... Skip to around 21:00:

Yes, that's one thing about digital- as long as you're just directly copying the footage, and not doing any sort of conversion and transcoding you can copy something a million times and it will still be exactly the same as the original.

All familar though, I have a VHS tape full of low quality multi-gen copies of old pres material that I was sent around 2004-ish!

Fascinating, though why anybody would want to do 23 generations of a VHS tape in the first place is beyond me but there you go.

Must watch that Channel 4 clip in full at some point, as that looks interesting as well. Thanks!
Just like I imagine Alzheimer's slowly takes away the memories of a beloved Sad

That's cheered me up no end.

Anyway, influenced by Hunkin I once did the same with some flash ident animations I stuck on a tape, was quite fun for a bit.

Speaking on Hunkin, I was at London Zoo a couple of weeks back, and there's a clock he designed outside the bird house there. Though the fact it was running 15 minutes slow doesn't speak too well for it...

The last time I was at the Science Museum they still had an exhibition based on The Secret Life of Machines in the basement

Yes, that's still there as well. Unless they've got rid of it in the past 11 days since I was last there anyway!
