When I started Premiere today I got a pop-up about the new clip extension tool. I tried it and was quite impressed. two seconds of video and ten seconds of audio created via their servers. I found it interesting when one clip I tried had writing on it and Premiere created letters. It's a very short clip. The last two seconds is the AI component - so you will need to stop and advance frame by frame to see what it does. On ordinary footage, it's difficult to spot. Great tool, because sometimes you just need a few extra frames - and the usual tricks often have a weird look (like a small slowing of speed to fill the gap)

How many times can you get an extra two seconds added on? :-D

I guess if you wanted to add 2 to an already extended one, you could just render the clip and bring it back in. I think though it will be using the credit system they started for photoshop. I discovered too that it can do the same to audio - but up to 10 secs of audio - so that's next to fiddle with.
