> I expect video upscaling next.

There is a directshow filter (madvr[1]) for windows that already offers a neural network scaler {NNEDI3, simpler network than waifu2x) in realtime.

Interesting... If a Neural Network can be used for up scaling a video it means that you need to send less data over the wire for getting the same quality. This means neural networks can be used as a compression algorithm.

from the flipboard article:

"The final use case that we thought of was saving bandwidth. A smaller image could be sent to the client which would run a client side version of this model to gain a larger image."

Can be applied to gifs and videos, but this really depends on the usage case and if the client would tolerate such a thing.

NNEDI3, which I mentioned in another comment, can be used for video upscaling, and was in fact built for video processing in the first place.
