My videos tend to have a lot of short clips. In some of them I need to time stretch a video uniformly. For example I might have 50 clips in a 5 minute video and want to shorten then uniformly by 40% in play time (i.e. set time stretch to 140%). Is there a way to globally apply the time stretch to all the clips at once? It gets very tedious to do them one at a time. I have tried all the tools I can think of to group then time stretch. All attempts have only allowed me to time stretch a single clip.
