Making the MiniMax H3 Video VAE 2x Faster
The MiniMax H3 video VAE now encodes up to ~2.2x faster and decodes ~1.4 2.7x faster. Together that can roughly halve the time a video workflow spends in the VAE: a 1344x768, 129 frame encode and decode round trip drops from 24.3 to 12.7 seconds. What changed, the technical details A fused encoder kernel, on by default. Between convolutions the encoder normalized each frame, applied an activation and padded the edges, each one a separate pass over hundreds of megabytes.
