As part of its MAX conference, Adobe traditionally shows off some of its more forward-looking tech, which may or may not end up in its Creative Cloud apps at some point in the future. The idea here is to show what its engineers are working on and right now, as you can imagine, that’s a lot of generative AI. With Firefly now being part of Photoshop and now also Illustrator, the next frontier here is video and unsurprisingly, that’s where Adobe’s most interesting ‘sneak’ of this year comes in. Project Fast Fill is, at its core, the generative fill the company introduced in Photoshop, but for video.

Project Fast Fill simply lets editors remove objects from a video or change backgrounds as if they were working with a still image, all with a simple text prompt. Users only have to do this once and the edit will then propagate to the rest of the scene. Adobe says this even works in very complex scenes with changing lighting conditions.
