The LTX2 Image-to-Video Workflow is a powerful, next-generation ComfyUI pipeline built on the latest LTX2 model, delivering exceptional performance in image-to-video generation. This workflow enables creators to transform a single image into a high-quality, long-form cinematic video (up to ~20 seconds) with significantly reduced generation times compared to earlier models.
LTX2 sets itself apart with support for very high resolutions (up to 4K) and built-in audio generation, making it one of the most advanced image-to-video solutions currently available.
Key Capabilities:
đŹ Long-Form Image-to-Video Generation
Consistently generates 19â20 second videos with stable visuals and smooth motion, outperforming many WAN-based workflows in terms of speed (excluding cold start).
đźď¸ High-Resolution Output
Tested safely up to 1920Ă1088 resolution without out-of-memory issues, with support extending toward 4K output depending on hardware and settings.
đ§ Video with Audio
Supports audio generation alongside video, with multi-language capability. English provides the most consistent results, while other languages perform reasonably well.
⥠Optimized Generation Speed
The LTX2 architecture delivers faster inference times while maintaining strong visual coherence and detail.
đ Prompt-Driven Quality Enhancement
For best results, this workflow benefits from detailed, image-aware prompts, as recommended by LTX2. Using tools like ChatGPT or other LLMs to describe the image and generate structured prompts can significantly improve motion, composition, and storytelling quality.
Performance Notes:
- Initial (cold start) runs may take longer; subsequent runs are noticeably faster.
- Stable generation observed during long-form tests with no lag or crashes.
- After a few iterations, users quickly learn how to prompt for cleaner and more cinematic outputs.
Best Use Cases:
- Cinematic image-to-video storytelling
- High-resolution AI video content
- Creative experiments with motion and audio
- Professional-quality AI video prototyping
The LTX2 Image-to-Video Workflow delivers a major leap in speed, resolution, and audio-enabled AI video generation. With the right prompts and a bit of experimentation, it unlocks a powerful new level of cinematic creativity inside ComfyUI.
