LTX 2.5 T2V / I2V Audio

Summary

LTX 2.5 ComfyUI workflow that keeps text-to-video and image-to-video under one simplified control node, with audio support and a two-stage generation/refinement pass.

Developer notes

• The source README says the workflow:
  • supports both T2V and I2V
  • has audio support
  • keeps control on a simplified main node
  • exposes duration, resolution, FPS, seed, prompt enhancement, and related toggles
• The source README also says it uses a two-stage generation and refinement setup.
• This is LTX 2.5, not LTX 2.3.

Our notes

• Worth watching because it looks simpler than a lot of LTX graphs and it includes audio in the same flow.
• Probably not the first thing to queue on an RTX 3070 / 8 GB, but it looks like a practical adjacent option if LTX 2.3 feels too cramped.
• The main value here is simplicity plus the two-stage refinement pass, not raw novelty.

Required custom nodes

• comfyui-crystools
• comfyui-kjnodes

Required model files

• Not spelled out in the source README.
• Expect the standard LTX 2.5 weight stack, encoders, and VAE components used by the workflow.

Notes

• Best same-day LTX workflow hit even though it is 2.5 rather than 2.3.
• Good adjacent import if you want to compare the newer branch against your current LTX 2.3 baseline.
