@Winnie_M Why has this quick action been removed? When I try to change speed using the link you provided, it forces me to start a new file. I don't want that 😞 I just want the quick action back. It was vastly more convenient when I just need to speed up or slow down a video and that's it. Going through the file route is way too much work for such a simple task.
You can change a video speed with the Quick Actions. You can do it directly here. You can upload the video and then choose among different speeds. Then, you can download the video or keep editing it.
