If your LTXVideo nodes stopped loading after updating ComfyUI, you did not break anything. A dependency called kornia gets pulled forward to 0.8.3 and the video node pack cannot import against it. The fix is one command, the issue has been open since June, and there is a real trade-off nobody mentions.
We benched LTX-2.5 for two full rounds and got confident, wrong answers, because the official templates ship an LLM prompt rewriter that is on by default and buried inside a subgraph. Here is how to find it, how to actually turn it off, and what the model does once your prompts reach it intact.
LTX-2.3 is the fast, local, image-to-video model that became our channel’s workhorse, 30fps, native portrait, faster-than-realtime. Here’s what it’s great at, where it slips, and why we moved talking to a specialist.
Our character’s debut music video, 18 shots, five sung sections, 2:13, rendered overnight on a single RTX 5090 for zero cloud spend. The complete pipeline: song, storyboard, renders, lip-synced vocals, beat-cut assembly.
Our 66-second monster movie, helicopter, dragons, a meta twist, cost $16 including every failed take. The full filmmaking pipeline: storyboards, cloud + local animation, score, assembly.
