The LTX2 Image-to-Video Fast HD Workflow is a refined, high-performance ComfyUI pipeline built on the latest LTX2 model, delivering outstanding results in image-to-video generation with exceptional speed, resolution, and visual quality. This workflow represents a significant upgrade over earlier versions, producing crisper motion, cleaner detail, and more stable long-form videosâall with reduced generation times.
Designed for both experimentation and production use, this workflow allows you to transform a single image into a cinematic HD video (up to ~20 seconds) with optional audio generation, making it one of the most capable image-to-video solutions currently available.
Key Capabilities:
đŹ Fast Long-Form Image-to-Video Generation
Consistently generates 19â20 second videos with smooth motion and stable composition, often faster than WAN-based workflows (excluding cold start).
đźď¸ HD to Near-4K Resolution Support
Delivers crisp results at 1024Ă576, with safe scaling up to 1920Ă1088 without out-of-memory errors. Higher resolutions are supported depending on hardware and configuration.
đ§ Video with Audio (Multi-Language)
Supports audio-enabled video generation in multiple languages. English offers the most consistent results, while other languages perform reliably for many use cases. mention only the dialogue/narration in spanish, german etc in " "
⥠Optimized for Speed & Quality
Improved inference pipeline delivers better visual quality than earlier LTX2 workflows while maintaining fast generation times.
đ Prompt-Driven Quality Enhancement
For best results, this workflow benefits from detailed, image-aware prompts. Using tools like ChatGPT or other LLMs to describe the input image and generate structured prompts can significantly improve motion realism, scene flow, and storytelling.
Performance Notes:
- First (cold start) run may take longer; subsequent runs are noticeably faster.
- Stable long-form generation observed with no lag or memory issues in testing.
- After a few iterations, users quickly learn how to guide prompts for more cinematic results.
Ideal Use Cases:
- Cinematic image-to-video storytelling
- AI short films and concept videos
- High-quality motion experiments
- Content creation with optional audio
The LTX2 Image-to-Video Fast HD Workflow combines speed, resolution, and audio support into a single, production-ready ComfyUI setupâunlocking fast, high-quality cinematic video generation from a single image with ease.
