In iMovie for macOS, you might want to make a transition longer between clips, so the transition between clips is slower. When you try to make the transition longer, you might see this alert:
Imovie 10.0.9
Scarica Apple iMovie 10.0.9 per Mac. Scarica in modo facile e veloce i migliori software gratuiti. When you import media or open a library in iMovie 10.1.11 or later on a Mac with macOS Mojave, a window appears that lists incompatible media files in your library. To convert incompatible media files immediately, click Convert in the window. IMovie creates copies of the media files in the H.264 format. The original files are moved to an iMovie.
This alert means iMovie needs more footage from one or both clips to create the overlap.
To make a transition longer, you can manually trim the clips next to the transition.*
* If you select 'Do not warn me again' in the alert, iMovie will automatically trim the clips next to a transition based on the duration you entered.

- Drag the clip towards the center to shorten the clip.
- Double-click the transition, enter the duration you want, then click Apply.
- If the alert reappears, trim more footage. Keep trimming until you can enter the duration you want.
