ComfyUI-Mova node

The ComfyUI custom node is not finished and still needs real work. What it already does well: it can run FP8 weights and has a workable low-VRAM / high-VRAM strategy (offload, streaming loads, expert swap).

Official MOVA defaults are about cfg 5 and 50 steps. On my hardware that was roughly 19 minutes for a 7 second clip.

LightX2V isn’t an official MOVA stack, it’s a Wan-style 4-step video distill. For experiments I baked it into the FP8 models anyway.

That path is much faster for me (45 seconds for 7s), but quality and audio are the weak spots. After a lot of back-and-forth (local Qwen3.6 coding assistant + Qwen3.7-plus) and still didn’t get a solid audio path (joint speech + sync, not just video with sound).

The video below is current results with the FP8 LightX2V models, take it as 'what this node can do today, not a polished fully working node'.

If you want a headache (or a starting point), this custom node is a reasonable backbone: Comfy wiring + memory plumbing are there,

generation quality, audio, and LightX2V behavior still need love. If you fix something, please share it.

These components are byte-identical between variants:

• Video VAE
• Audio VAE
• Tokenizer (tokenizer/)
• Scheduler (scheduler/)
• Text encoder /text_encoder/umt5_xxl_bf16_ComfyUI.safetensors (Load CLIP wan type)
