One Server, Every Mode: MiniMax H3 Goes From Static Frames to Full Video Editing on Two RTX PRO 6000
H3 ships as two checkpoints: FL2VA (text + first/last frame) and Ref2VA (references including video). Serving both DiTs from one process took three failed hypotheses, a basename-sensitive model resolver, a 66 GB minimal partition download, and one multipart field spelled plural. Now one systemd unit serves text-to-video, keyframe animation, and video editing at 56 GiB per GPU, validated end to end.
