A method for lossy video encoding, transmission and decoding, the method comprising the steps of: receiving a first frame and a second frame at a first computer system; determining a first flow between the first frame and the second frame; determining a second flow based on the first frame and the second frame; encoding an input based on the first flow and the second flow using a first trained neural network to produce a latent representation; transmitting the latent representation to a second computer system; decoding the latent representation using a second trained neural network to produce an output flow; and using the output flow to obtain an output frame, wherein the output frame is an approximation of the second frame.
