1. Check the workflow before installing
Start from the workflow JSON supplied by the model or node package. Confirm the checkpoint filename, sampler, VAE and output node; do not assume a workflow for LTX-2.5 also works for LTX-2.3.
- Use a clean ComfyUI environment or a dedicated portable install.
- Keep model files in the package-defined folders.
- Record the package version and checkpoint name with every test run.
2. Use conservative first-pass settings
For a first render, use a short clip and 720p output. Move to 1080p only after the graph completes and the motion is stable. The hosted LTX-2.3 route supports 480p, 720p and 1080p for 5–20 second clips.
- Text-to-video: describe subject, action, camera and lighting.
- Image-to-video: keep the reference image dimensions consistent with the target aspect ratio.
- Lower resolution or frame count when a graph runs out of VRAM.
3. Diagnose failures by layer
A red node is usually a missing model file, an incompatible custom node, or insufficient memory. Read the first error in the console, then validate the checkpoint path before changing sampler settings.

This is a recipe for a verifiable test. It is not a claim that every ComfyUI package exposes identical defaults.
