☠️ Do not use any extra speed-up tricks or LoRAs or it may mess up your generations ... 🤬

⚠️ Hint: Most of the time the model is taking you by word. If you write "white" it is white. "Translucent" is translucent... like for the fluids. 💦 Now you know! 🫵 translucent whitish 🤫

Recommended specs:

8 GB VRAM, 32 GB RAM

Sample times: <2 minutes for 81 frames, 4 steps on RTX 4070 Ti Super.

Compatible with 14B LoRAs.

I normally use 0-2 LoRAs, strength at 0.4-1 depending on how much the effect should be. 0.7-0.9 works best most of the time, not overwriting the style of an image.
At multiple LoRAs is seems best to tune the strength a bit down to 0.3-0.6.

I can go wild on setting with this full checkpoint, even with added LoRAs:

• 121 frames possible: ~ 3 minutes

• 121 frames on 24 fps possible (more motion): ~ 3 minutes

• 128 frames on 24 fps possible (more motion and extended): ~ 3.5 minutes
