Audio to Video (Lip-sync)

The main node. Accepts:

  • image — ComfyUI IMAGE (auto-resized to max 1920px, uploaded automatically)
  • audio_path — local path to .mp3, .ogg, or .wav (auto-converted to MP3)
  • prompt — describe the motion/scene
  • api_key — your LTX API key
  • model — ltx-2-3-pro (best) or ltx-2-3-fast (quick tests)
  • resolution — 1080x1920 (portrait) or 1920x1080 (landscape)
  • duration — seconds (0 = auto-match audio length)
  • negative_prompt — what to avoid

⚠️ Audio-to-video only supports 1080x1920 or 1920x1080.
Images larger than 1920px are auto-resized. OGG/WAV files are auto-converted to MP3.

Notes

  • All uploads go through uguu.se (temporary HTTPS hosting required by LTX API)
  • Videos are saved to ComfyUI's output/ directory
  • ffmpeg required for OGG/WAV → MP3 conversion
