LTX 2.5 LoRA Slow Motion Control
Image-to-video LoRA that turns physical motion speed into a knob — real-time through 40× slow-motion — while the output stays at 24 fps playback. Standard LoRA, no reference video, no preprocessing. The one LTX 2.5 Creative Lab repo that is not gated, and it ships an official ComfyUI workflow (LTX-2.5_I2V_Speed_Control_flow.json). Place in models/loras/.
Released 2026-09-15 · Source: Lightricks/LTX-2.5-22b-LoRA-Slow-Motion-Control (HuggingFace) — Card: without the LoRA, pushing motion fps high mostly produces smearing; with it you get high-speed-camera-style slow motion.

Will this run on my GPU?
Minimum: 24GB VRAM.
Recommendation: Needs a pipeline that exposes the speed value: keep frame_rate at 24 and set speed = 1.0 (real-time), 0.5 (2×), 0.2 (5×), 0.1 (10×), 0.05 (20×). No trigger word — write a normal I2V caption and do not add 'slow motion' or fps wording. Through a generic LoRA loader that ignores speed you get a plain LoRA and none of the effect.

Common issues
ComfyUI doesn't see the file after I downloaded it▼
Make sure the file is in ComfyUI/models/loras/ (not a subfolder). Restart ComfyUI fully — the menu refresh sometimes misses new files. Filename must match exactly: ltx-2.5-22b-lora-slow-motion-control-1.0.safetensors.
CUDA out of memory error when loading the model▼
ltx-2.5-22b-lora-slow-motion-control-1.0.safetensors needs ~24GB VRAM minimum. If you're hitting OOM: • Enable Sequential Offloading in ComfyUI settings • Lower the resolution (768×512 instead of 1280×704) — both dimensions must be divisible by 32 • Reduce frame count (65 frames instead of 161) — must be 8n+1 • Use a smaller variant — see Related models below.
How do I apply this LoRA in ComfyUI?▼
Load it in a 'LoraLoader' node and connect it after your model loader. Pair this LoRA with the dev base model (not the distilled one) for the right behavior. LoRA strength 1.0 is the trained value — start there.
