LTX 2.3 video with generated audio

Generate a video with audio from a text description using LTX 2.3. No image, video, or audio upload is required. For a first run, replace the example scene and sound prompt with your subject, setting, action, camera movement, dialogue, and sounds. Review the negative prompt, choose the requested width and height in pixels, and enter a positive duration in whole seconds. Keep the advanced sampling and encoding defaults for the first run. The source defaults request a 900 × 1600 portrait video lasting approximately 20 seconds at 24 FPS. Initial sampling jointly generates video and audio at half the requested spatial size. A fixed 2× latent upscaler feeds a second sampling stage, whose video is decoded for the final result. The returned soundtrack is decoded from the first stage; refinement settings do not replace it. Actual dimensions and duration can differ from the request because of latent spatial and frame-count constraints. Playback FPS controls playback, audio timing, and duration-to-frame conversion. Conditioning FPS is a separate control used by both sampling stages: change both fields together and keep them equal. Use playback FPS within the downstream video's supported 1–120 range. Each sampling stage has its own seed, CFG, sampler, and editable manual noise schedule in advanced settings. Seed -1 randomizes that stage; a fixed nonnegative seed reuses its noise. To reuse both stages' noise, set both seeds. The schedules define sampling intervals directly, so there is no separate steps control. Negative conditioning is connected to both stages, and its effect depends on their CFG settings. The optional fixed distillation LoRA starts disabled, matching the source. Enable its stage to make the LoRA strength operative. The base quantized model, text encoders, VAEs, 2× upscaler, and memory patches are fixed implementation choices. Output settings select the container, codec, bit depth, and compression quality. Start with MP4, automatic codec, 8-bit precision, and automatic CRF (-1). Container and codec must be compatible; 10-bit output also requires compatible encoding and playback. The source's 8 GB hardware claim is not a verified runtime guarantee. Dependency evidence is incomplete: the inventory lists an older upscaler than node 23 selects, and node 26's first text encoder filename has a doubled .safetensors suffix. The graph preserves those source model selections.
