Made a 4 minute video with a 53 word single prompt, with my new video pipeline tool that goes from a simple or complex single prompt to a full video. I haven't fully tested the maximum length based on the context window I have but its a revolutionary product on consumer hardware. RTX 4090 laptop

# Workflow

The official workflows from [ComfyUI/Lightricks](https://github.com/Lightricks/ComfyUI-LTXVideo/tree/master/example_workflows/2.3), [RuneXX](https://huggingface.co/RuneXX/LTX-2.3-Workflows/tree/main), and unsloth (GGUF) all felt too bloated and unclear to work with comfortably. **But maybe I just didn't fully grasp the power of their parameters and the range of possibilities they offer.** I ended up basing everything on [princepainter's ComfyUI-PainterLTXV2](https://github.com/princepainter/ComfyUI-PainterLTXV2) — his combined dual KSampler node is great, and he has solid WAN-2.2 workflows too.

I haven't managed to get truly clean results yet, but I'm getting closer. Still not sure how others are pulling off such high-quality outputs.

Below is an example workflow for Dev models — kept as simple and readable as possible.

Not all videos are included here — only the ones I thought were the best (and even those are just decent in dev). Everything else, including all workflow files, is available on Google Drive with model names in the filenames: [**Google Drive

# Benchmark Results

Each model was run twice — first to load, second to measure time. With GGUF models something weird happened: upscale iteration time grew several times over, which inflated total generation time significantly.

**Dev — 1280x720, steps=35, cfg=3, fps=24, duration=10s (241 frames), no upscale** samplers: euler | schedulers: linear\_quadratic

# Shameless Self-Promo

I built this node after finishing the tests — and honestly wish I had it during them. Would have made organizing and labeling output footage a lot easier.

[**Aligned Text Overlay Video**](https://github.com/Rogala/ComfyUI-rogala?tab=readme-ov-file#aligned-text-overlay-video)

Renders a multi-line text block onto every frame of a video tensor. Supports `%NodeTitle.param%` template tags resolved from the active ComfyUI prompt.
