via “upsampling and downsampling with spatial-temporal awareness”
Implementation of Make-A-Video, new SOTA text to video generator from Meta AI, in Pytorch
Unique: Implements sampling operations that explicitly preserve temporal dimensions (frame count) while modifying spatial resolution, rather than treating video as 3D volume where all dimensions are sampled uniformly
vs others: More efficient than naive 3D sampling (which would reduce frame count) while maintaining temporal information, enabling practical multi-scale video processing
