Comparison: Switching back to LTX 2.3 from MiniMax H3 for Lip-Sync Workflows

The author compares MiniMax H3 with LTX 2.3/2.5 on a 3090/64GB setup. While H3 offers better speed and first-attempt success rates for general 15-second 1MP video generation, it fails to meet the author's specific needs for Image-to-Video with lip-syncing (IA2V), a task that constitutes 90% of their work. H3 often injects random text during silent moments. Consequently, the author is returning to LTX 2.3, which excels at this specific workflow, and criticizes LTX for not yet releasing an official IA2V ComfyUI workflow.
