We have already mentioned the new feature notice on AI generated content. AI marking is now also available for video/audio elements. Here, you can also specify whether the text of the markup should include only the video/audio, only the subtitles, or both.
In addition, if you generate subtitles using the AI button (regardless of whether you edit them afterwards), LXT automatically creates an AI label or updates it if the subtitles are not yet mentioned in the label text.
