alt Hacker NewsWhat type of compression would change the relative scale of elements within an image? None that I'm aware of, and these platforms can't really make up new video codecs on the spot since hardware accelerated decoding is so essential for performance.
Excessive smoothing can be explained by compression, sure, but that's not the issue being raised there.

One that represented compressed videos as an embedding that gets reinflated by having gen AI interpret it back into image frames.
AI models are a form of compression.
Neural compression wouldn't be like HVEC, operating on frames and pixels. Rather, these techniques can encode entire features and optical flow, which can explain the larger discrepancies. Larger fingers, slightly misplaced items, etc.
Neural compression techniques reshape the image itself.
If you've ever input an image into `gpt-image-1` and asked it to output it again, you'll notice that it's 95% similar, but entire features might move around or average out with the concept of what those items are.

Video compression operates on macroblocks and calculates motion vectors of those macroblocks between frames.
When you push it to the limit, the macroblocks can appear like they're swimming around on screen.
Some decoders attempt to smooth out the boundaries between macroblocks and restore sharpness.
The giveaway is that the entire video is extremely low quality. The compression ratio is extreme.
