2.5 Suite | LTX2.3 Double Digital Human | IC Edit 100% No Subtitle Dialogue

This is a highly stable, subtitle-free, dual-character dialogue video application based on LTX2.3 Dual Digital Human + Image-Driven + Audio-Driven + PromptRelay Segmented Dialogue Control + Dual-Character Role LoRA + IC Edit Subtitle Removal / Watermark Removal LoRA + NAG Audio-Visual Condition Enhancement + Third-Order Rendering Polish. Users upload a dual-character first-frame image and a piece of dialogue audio. The system first extracts the human voice, then encodes the audio into Audio Latent, fusing it with the Video Latent of the dual-character scene, allowing the two characters to produce natural lip-syncs, expressions, eye contact, and subtle movements according to the rhythm of the dialogue.

Compared to ordinary dual-character digital humans, this version focuses heavily on enhancements in dual-character framing stability + clean, subtitle-free final footage. It incorporates Dual-Character LoRA, VBVR motion enhancement, motion tracking control LoRA, NAG audio-visual condition enhancement, IC Edit subtitle removal LoRA, IC Edit watermark removal LoRA, and strong negative prompts to reduce common issues in dual-character dialogues such as left-right positioning drift, character identity swapping, facial alterations, residual subtitles, watermarks, garbled text, and visual artifacts. The core advantage is: one dual-character image + a piece of dialogue audio generates a subtitle-free, watermark-free dialogue video with more stable dual-character positioning. When using, it is recommended to focus on controlling four items: the dual-character first-frame image determines character identity and left-right positioning, the driving audio determines the dialogue rhythm, the global prompt (used to write overall scene rules) determines the setting and character relationships, and the segmented prompts (writing action changes for each time period) determine the dialogue, expressions, and interactions for each segment.
