Extreme speed-up of Wan 2.2 T2V and I2V with just 4 steps

https://huggingface.co/lightx2v

Update: 25/10/30

• Refined HIGH lora, extracted from kijai from the most recent checkpoint of lighx2v

• https://huggingface.co/Kijai/WanVideo_comfy/tree/main/LoRAs/Wan22_Lightx2v

• not an official lighx2v lora

• key warnings can be ignored (unused weights)

Update: 25/10/23

• Added new release 1022 of Lighx2V LoRAs

• Quality seems improved

• Possible no ghosting anymore

• Compatible to other LoRAs

Update: 25/10/15

• MoE-Distill is the latest speed-up LoRA

• Patched version from KJ (HIGH)

• Restores some motions compared to other speed-up's

• Quality seems high

Needs more testing. Some situations are still slow motion.

Use: Euler+simple, Sigma-Shift 5, CFG 1

⚠️ Attention

• Some configurations seems to blur/ghost

• It seems incompatible with some LoRAs (e.g. NSFW)

• It seems incompatible some checkpoints

Update: 25/08/21

• More Sampler+Scheduler info

• ATM: The LoRAs cause a bit slowdown compared to native sampling without

Update: 25/08/08

• The I2V Lora-Upload seem to be broken, re-uploaded it again

• Changed some Usage descriptions

• Mentioned scheduler/sampler combo

Update: 25/08/07

• Added I2V LoRAs

Update: 25/08/05

• Added more Infos and LoRAs fix1

Usage

SwarmUI

1. CFG: 1

2. Steps: 4

• For T2V Use with this at the end of your prompt: <base> <lora:Wan2.2-Lightning_T2V-A14B-4steps-lora_HIGH_fp16> <refiner> <lora:Wan2.2-Lightning_T2V-A14B-4steps-lora_LOW_fp16> (adapt the lora filenames to whatever specific filenames you have locally)

• For I2V, use <video> <lora:...i2v-high> <videoswap> <lora:...i2v-low> and of course use the i2v loras

• the I2V Lightning LoRA appears to target 16 fps

General:

• 1 strength on both

• 2+2 steps (total 4)

• switch at 2 (50%)

• Sigma Shift: 5

• Sampler + Scheduler combinations:

  • Euler + Beta

  • LCM + LTX

  • Euler + Simple

• You need to be very descriptive, short prompts leading to much more random things.

• work best at 81x480x832, 81x832x480, 81x720x1280, 81x1280x720

usage tip first loras (outdated):

• 0.125 strength on both

• 4 steps

• switch at 2

Did not figured out optimal settings for comfyui or swarmui ... still testing. Let me know! :)
