LTX 2.3 T2V Simple Single Pass

Summary

Simpler text-to-video only LTX 2.3 workflow from the RuneXX pack. Chosen because it avoids some of the extra image-input complexity while still staying in the lower-bloat part of the workflow pack.

Developer notes

• Same general workflow family as the other RuneXX imports, built around the extracted Kijai model layout.
• The pack is designed to support both standard and GGUF-oriented loading choices, depending on what the user has installed.

Our notes

• This is probably the simplest LTX 2.3 text-to-video import we currently have.
• On a 3070, it is still a “tight to heavy” experiment, but it is a better first look than the more elaborate prompt-relay or long-video graphs.
• Good candidate for a later optimized low-complexity LTX master if the outputs are decent.

Required custom nodes

• ComfyUI-KJNodes
• rgthree-comfy
• easy use / easy showAnything

Notes

• Best LTX pure T2V starter in the current batch.
