## Routing Metadata

- Family: `video_t2v_i2v_avatar`
- Input modalities: `image, text_prompt`
- Output modalities: `video/mp4`
- Model families: `ltx`
- Node count: `34`
- Complexity score: `9`
- Resource profile: `very_high`
- Estimated runtime: `heavy (can exceed 6 min; best on high-VRAM GPU)`
- Max latent resolution hint: `None`x`None`
- Max sampler steps hint: `None`

## Detected Models

- `clip`: `t5xxl_fp16.safetensors` -> `models/clip`
- `checkpoint`: `ltxv-13b-0.9.7-distilled-fp8.safetensors` -> `models/checkpoints`

## Detected Custom Nodes

- `ComfyUI-LTXVideo`
- `comfyui-easy-use`
- `comfyui-kjnodes`
- `comfyui-videohelpersuite`

## Runtime Warnings

- Large model(s) detected; ensure enough VRAM and disk space.
- Multiple custom nodes required; verify node installation/version compatibility.
- Video workflow: usually slower and VRAM-intensive than still-image workflows.
