Lightricks drops LTX HDR for professional 16-bit AI video

Lightricks released LTX HDR, an In-Context LoRA that upgrades the LTX-2 foundation model to generate 16-bit High Dynamic Range video. It outputs linear half-float EXR frames that plug directly into professional VFX and color grading pipelines.

// ANALYSIS

Breaking the 8-bit SDR barrier is exactly what AI video needs to graduate from social media demos to high-end VFX workflows.

–Standard AI video models clamp highlight and shadow detail, rendering the output largely unusable for professional colorists.
–LTX HDR uses a logarithmic encoding strategy (LogC3) to map high dynamic range data into a latent space compatible with LTX-2.
–Outputting industry-standard EXR frames means AI-generated clips can finally be properly composited alongside traditionally filmed assets.
