LTX-2 DEV - IMAGE to Video and TEXT to Video with Ollama

LTX-2 DEV Video with Audio:

Image to Video and a Text to Video workflow, both can use own Prompts or Ollama generated/enhanced prompts.

• setup for the LTX2 Dev model.

• uses Detailer Lora for better quality and LTX tiled VAE to avoid OOM and visual grids

• 2 pass rendering (motion+upscale). Upscale process uses distilled and spatial upscale Lora

• setup with latest LTXVNormalizingSampler to increase video & audio quality.

• Text to Video can use dynamic prompts with wildcards.

I am using these starting parameters for ComfyUi to avoid OOM (my setup: 16g Vram/64g Ram):

--lowvram --cache-none --reserve-vram 6 --preview-method none

Find Model/Lora Loader nodes within Sampler Subgraph node.

• (reads prompt only, fast): https://ollama.com/goonsai/josiefied-qwen2.5-7b-abliterated-v2

• alternative model with Vision (reads input image+prompt, slower): https://ollama.com/huihui_ai/qwen3-vl-abliterated
