Workflow: Image -> Autocaption (Prompt) -> WAN I2V with Upscale and Frame Interpolation and Video Extension

• Creates Video Clips with 480p or 720p resoltion.

There is a Florence Caption Version and a LTX Prompt Enhancer (LTXPE) version. LTXPE is more heavy on VRAM

V1.0 WAN 2.2. 14B Image to Video workflow with LightX2v Lora support for low steps (4-8 steps)

• Wan 2.2. uses 2 models to process a clip. A High Noise and a Low Noise model, processed in sequence.

• compatible with LightX2v Lora from Wan2.1 to process clips fast with low steps.

• compatible to some of the Wan2.1 Loras, required to inject twice due to 2 model setup.

• See notes in workflow.

• GGUF models

• 5sec clip with 6 Steps @ 480p take about 4mins, including autoprompt, 2x upscaling to 960p & frame interpolation to 30fps. (RTX4080-16gb Vram and 64gb Ram, sage attention)

WAN 2.2. I2V 5B Model (GGUF) workflow with Florence or LTXPE auto caption

• lower quality than 14B model and currently slower (there is no LightX lora)

• 720p @ 24 frames

Tips:

• Default strength of LightX2v Lora with 0.8 is setup for a more realistic look, hair and skin look more real. For anime or comic like look you can increase strength to 1.0 or beyond (black nodes in wokflow)
