LTX 2.3 Pro Image to Video

LTX 2.3 Pro Image to Video is an image to video model. Start from a photo and let the model find the motion. The cheap, fast one — and the only one that goes to 4K. People run it for: cheap, 4k, fast, native audio.

12 credits for a 6 s clip. It bills per second of output at 2 credits a second, so a shorter clip costs proportionally less. Billing stops at 10 seconds, so one run never costs more than 20 credits. Credits are the only unit we quote. One balance covers every model in the catalogue, so there is no subscription attached to LTX 2.3 Pro Image to Video specifically and no minimum spend to use it. See the pricing page for what a credit costs.

It accepts an image and a text prompt. It will not start without an image and a text prompt. One reference image per run. Resolutions: 1080p, 1440p, 2160p. Aspect ratios: 16:9, 9:16.

Every run returns one video. A single run gives you between 6 and 10 seconds. It produces the audio along with the picture. Runs are queued and processed in the background, so you can close the tab — the finished file turns up in your library. We do not quote a fixed wall-clock time: it moves with the length of the run and with how busy the queue is.

The catalogue also runs HappyHorse 1.1 Image to Video (10 credits for a 5 s clip), Kling 3.0 Pro Image to Video (10 credits for a 5 s clip) and Kling O3 Pro Image to Video (10 credits for a 5 s clip) for the same job. HappyHorse 1.1 Image to Video is our default pick for image to video, and the cheaper option at 10 credits. They all draw on one credit balance, so trying a second one costs nothing beyond the run itself.
