fal has launched serverless access to LTX 2.3 Quality, a multimodal video generation model built for high-fidelity output. It supports text, image, and audio-to-video workflows where sound tracks guide visual motion. This release includes native High Dynamic Range (HDR) rendering, delivering per-frame EXR files alongside standard MP4 previews.

This update targets production-ready AI assets for professional VFX pipelines. By offering EXR framesā€”a standard format for high-end post-productionā€”fal is moving toward cinematic quality. This follows an industry trend toward professional standards and tracks alongside the HeyGen HDR update that brought high-fidelity rendering to its framework.

Users can access the model via the fal API to generate videos or apply styles using LoRA variants (small weights for style customization). The service costs $0.0024075 per megapixel of generated video. This launch expands the platform's video library, which recently added the Grok Imagine Video 1.5 release and now joins the NVIDIA Cosmos 3 Super launch.

Still wondering? A few quick answers below.

LTX 2.3 Quality is a multimodal video generation model hosted on the fal serverless platform. It is designed for high-fidelity output and supports multiple input types, including text, images, and audio. The model is optimized for professional production workflows by offering native HDR support and customizable style variants.

The audio-to-video workflow allows users to provide an audio track that the model uses to guide the motion and timing of the generated video. This ensures that visual elements like character animation or scene transitions are synchronized with the sound, making it suitable for music videos or cinematic clips.

LTX 2.3 Quality provides native High Dynamic Range (HDR) rendering, which captures a wider range of color and light than standard video. For professional VFX pipelines, the model can output per-frame EXR files, which are the industry standard for high-end post-production, alongside a standard MP4 preview.

The model uses a usage-based pricing structure on the fal platform. Users are charged $0.0024075 per megapixel of generated video data, which is calculated by multiplying the width, height, and number of frames. For example, a 1280x720 video with 121 frames costs approximately $0.270 to generate.
