Good afternoon
How to stretch several elements (pictures) at the same time?

There are several pictures with transition effects and an audio track (much longer than the video sequence). How to fit the video sequence to the music in one step (rather than stretching each photo)

Did this Telegram chat solve your problem?

Ha, I know something, I still know this from Cinelerra. Combine the desired area (nested) and then edit it as a unit.
