I can show you an algorithm that compresses an entire 2 hour movie to a single bit, but it only works on one movie.
Ah I got it to work for two movies :)
You just made disco stu very happy, if these trends continue- 'Ey!
I think the most impressive movie compression technique is youtube. It compresses movies into a short sequence of characters denoted as URLs.
You only need one copy of it - even if it is 100GB. If it's baked into every OS... and storage / RAM keeps getting cheaper... just might work.
Meh, AI doesn't break information theory. The relationship between the prompt size to the "similarity" of the result will be such that it doesn't beat traditional compression techniques.
At best we might consider it a new type of lossy (or... replacey?) compression. Of course if storage / RAM / bandwidth keeps increasing, this is quite likely the least energy efficient technique available.
If the compression can take into account the sub-manifold of potential outputs that people would actually be interested in watching a movie about it can achieve enormously higher compression than if it doesn't know about this.
Unproven - but yes like I say - a new type of compression
Not new. If you have a preshared dictionary even zstd can give you better compression.
