- Works on slow connections: for Kling O3 video editing and other features priced by the reference video's length, if your browser can't read the video's length right away, our server reads it instead, so the price shows as usual and you can send.
- Clear status while reading: the panel shows "Reading the reference video's length…" while it works, and if reading fails it tells you why and offers a Retry button, so you don't need to reload the page.
