LTX 2 - AI Video Generation

Can I generate portrait video directly in LTX 2, or do I need to upscale from landscape?

LTX 2 generates native portrait video up to 1080×1920, so you don't need to convert or upscale from landscape. This native support means portrait output is built into the model rather than a post-processing step, which matters for quality and speed if you're building products for mobile or vertical platforms.

What's the longest single video clip LTX 2 can generate in one request?

LTX 2 generates up to 20 seconds per clip. The tool also supports long-form video generation, though you'll want to check their documentation or contact their team about how that workflow handles stitching and consistency across multiple segments.

Can I run LTX 2 on my own infrastructure, or am I locked into their API?

You have three deployment options: API access, open source model weights you can run locally, or on-premise deployment. The open weights mean you can inspect and modify the model itself, which is unusual for production video generation tools and useful if you need full control or have strict data residency requirements.

Does LTX 2 output in HDR, or is that something I need to add in post-production?

LTX 2 can generate HDR output directly through a feature called IC-LoRA, so you don't need to grade it afterward. That said, LTX 2 does not publish detailed specs on color space options or format flexibility, so verify their output specs match your pipeline before committing.
