1From its documentation

LTX offers an API that turns text, images or audio into 4K video with synchronized sound and returns an MP4. Async jobs are polled, at least five seconds apart, and output URLs expire on their own schedule, so results should be downloaded or re-hosted once a job completes. The rules of its own film contest allowed editing through an XML export.
