NEW v1.2 - Simpler and Cleaner with RefMods.

Generate LOW RESOLUTION in a first Pass, then upscale and refine when happy with the low quality resolution results.

Features:

• Add RefMods or image references.

• Enable or disable the high-resolution upscaling and refinement in the 2nd Pass.

• Keep the same seed to produce small videos first to check for audio quality and composition before enabling the 2nd pass to upscale to higher resolution

• Add your desired Loras, individually to each pass to ensure the Lora weights are applied accordingly
