Try an example, and see the clips at once
The example button used to fill the box with a YouTube link, which still meant a wait and a credit. It now opens a video we have already cut.
The button existed to answer what do I actually get. It answered come back in ten minutes: it filled the input with a YouTube address, so you still spent a credit and still waited for a render before seeing anything.
It now opens a job that is already finished. The clips, their scores, their titles and the editor, with nothing queued and no credit spent.
The clips are served through the same route as your own, which signs their links freshly on each visit. The stored links expire after forty eight hours, so an example built on those would have worked for two days and then shown black rectangles.
The source is a Creative Commons video, and its licence was read from YouTube's own interface for machines rather than from the page, which does not carry it.
2 videos a month, no card. What is still being built is on the roadmap.
