Facebook parent company Meta Thursday announced Make a Video, an online tool that generates short movie clips based on a text description. Why it matters: Text-to-still-image AI systems, including DALL-E 2, Stable Diffusion, and rival projects from Google, Meta and others, have advanced with great speed over the past year. Now, Meta appears to have won the race to extend AI-based content creation to videos. Details: As with the still-image generators, all people have to do is describe something they want to see in a verbal prompt and the system returns a visual result -- in this case, a video. The big picture: AI image generators have wowed observers, but they also raise significant concerns regarding ownership, privacy, the data sets they're based on and the impact their advent may have on artists' income and employment.
