minimax-h3-ref2va-q4
MiniMax-H3 served by vllm.cpp, LocalAI's own C++ port of vLLM. It generates
video AND audio jointly, so a clip comes back as an MP4 with a real
soundtrack rather than a silent render.
This is the Q4_K_M quantisation of the Ref2VA partition, the one that takes
REFERENCE conditioning: a reference image, a reference clip, or reference
audio, prepended as their own blocks so the subject or style carries into the
generated video. For plain text-to-video or first/last-frame conditioning use
minimax-h3-fl2va-q4 instead - the two partitions are separate checkpoints and
each refuses the other's tasks.
Use this Q4_K_M build, NOT the NVFP4 Ref2VA weights: NVFP4 renders a
multicolour patch grid, and it took three investigations upstream to
establish that the fault is the quantisation rather than the reference path.
On Q4_K_M the same code renders coherently.
Roughly 40 GB of weights across five files, plus the two VAE configs that
carry the latent statistics. The default canvas is 1344x768 at 124 frames and
24 fps, about 5.2 seconds. Generation is slow - roughly 176 s per denoise
step at that canvas on a 20-SM device, so the 50-step default is a multi-hour
job. Muxing the finished frames needs ffmpeg on the host.
