If you trimmed a movie file in your iPhoto 9.5 library, you will first need to drag it to your desktop before you can send it in Mail.
- Locate the movie in your iPhoto library.
- Drag your movie to the Desktop. iPhoto will create a new copy of your trimmed movie.
- Drag the movie file from your Desktop into a new Mail message.
Note: Most email providers limit the size of outgoing emails. If your video is too large, try trimming the video to be shorter in iPhoto or Export the video to a lower resolution in QuickTime.
