⚙️ How It Works

1. Load the LTXV Model – Use CheckpointLoaderSimple to load ltx-video-2b-v0.9.safetensors.
2. Encode Prompts – Encode both positive and negative prompts using CLIPTextEncode.
3. Generate Latent Video Space – Use EmptyLTXVLatentVideo to define resolution and frame length.
4. Apply Conditioning – Feed text encodings into LTXVConditioning for generation control.
5. Setup Scheduler & Sampler – Connect LTXVScheduler, KSamplerSelect, and SamplerCustom.
6. Decode & Export – Use VAEDecode to convert latent to image frames.
7. Combine Frames into MP4 – The VHS_VideoCombine node compiles frames into an MP4 file with preview options.
