JoyAI-Echo x LTX-2.5 (echoVid) - DEV merges

Bring your own distill LoRA. These are the LTX-2.5 dev transformer with JoyAI-Echo's video attention / feed-forward delta transplanted in (070T30 = 0.7 x delta, 0.3 x on the modulation tables; 100T50 = 1.0 x / 0.5 x) and NOTHING baked on top - no distillation. Use them like LTX-2.5 dev: apply the official ltx-2.5-22b-distilled-lora-450 (Lightricks/LTX-2.5, loras/) with a Load LoRA (model only) node at the strength you like (0.4-0.6 is where the picture holds its natural grade; 1.0 is fully distilled), or any other distill / style LoRA, then run the distilled 8-step schedule. Or run them slow, as a dev model (25-30 steps, cfg ~3).

The ready-made few-step files (this delta with the official distill LoRA baked at 0.5) are in joyai-echo-ltx25-echoVid-gguf (RTX 30/40) and joyai-echo-ltx25-echoVid-comfy-native (RTX 50). Workflows + nodes: https://github.com/jlucasmcrell/ComfyUI-JoyLTX25

What it looks like

Rendered with the files on this page (070T30, distilled LoRA baked at 0.5), the ComfyUI-JoyLTX25 canvases, 8 steps at cfg 1. Sound is generated with the picture, in the same pass - turn it on.

Three shots joined into one take

Multishot, 3 x 8 s at 1280x736, AV-extend joins - the speech and the room carry across both joins with no reference photo attached.

Beach, hard sun

10 s, single generation, picture and sound together.

Wet neon street

10 s, single generation. Reflections and rain with a voice over them.

Snow, flat overcast

10 s, single generation. The grade holds in high key - the failure mode of the first build.

Files

Both doses: 070T30 and 100T50 in the file name. LoRA-on-int8 works in stock ComfyUI (it is how Lightricks ship LTX-2.5 dev + distilled LoRA).
