V2V Change any video to new style, new characters, add VFX & more with LTX-2.5 Ripple Lora

This powerful lora can change your video in so many ways, just by changing the first frame of the video.
You can change the first frame in a photo editor, in ComfyUI edit image workflows, or ask your favorite LLM to to it for you ;- )
The looks of the first frame ripple through the entire video with the Ripple First Frame All Frames (FFAF) IC-LoRA from @WepeNerd

The ripple lora:

Adding Special Effects
Re-texturing
Style Change
Light source / time of day change
Character Change
Background Change
Weather Change
Title/Logo Replacement
Object Addition / Removal / Replacement

and so much more... imagination is the limit ; - )
