Welcome to my 💫🎦 Friendly LTX-2.3 T2V+I2V+FLF+Lipsync

✨ Less mess, more magic

·        Unified VIBE FLF - Lipsync all-in one version including First Last Frame mode with latest quality enhancers and VibeVoice implementation for voice cloning

• Unified Omni - Lipsync all-in one version with latest quality enhancers and OmniVoice implementation for voice cloning

• Unified ID - Lipsync all-in one better quality version with two-stage video generation and ID-Lora implementation for voice cloning

• Unified Light - Lipsync all-in one version with single-stage video generation

LTX-2.3 is a state-of-the-art DiT-based (Diffusion Transformer) audio-video foundation model developed by Lightricks. It represents a significant evolution from LTX-2, delivering enhanced audio and visual quality alongside improved prompt adherence. The model is specifically designed to generate synchronized video and audio within a single unified architecture, making it a powerful tool for multimodal content creation.

I offer my unique workflow with convenient options control and all-in-one structure (audio, t2v, i2v)

💻 System requirements:

• Minimum system requirements for 540p i2v and 720p t2v:

RTX 3000-s, 8GB+ VRAM, 45GB+ RAM, 8-core processor, SSD, latest ComfyUI

🚀 Low VRAM optional optimization:

• For systems with low VRAM use --reserve-vram ComfyUI parameter in run_nvidia_gpu.bat: --reserve-vram 4 (or other number in GB).

📌 Detailed tips and links to models in the workflow

✨ Workflow features:

• Extremely user-friendly interface
