LTX I2V Workflow: Remove Fake Subtitles with NAG + Crop

LTX sometimes adds fake subtitles or random on-screen text when generating talking-head videos. In this video, I walk through the exact tests I used to remove them inside ComfyUI. We start with the stock LTX I2V template, test negative prompts, remove dialogue from the prompt, then try NAG, a black bar trap, and finally the image extension + crop method.
