imovie How does the video clip tool export a playable file?

How to operate:

1, click on the top task bar "file", and then select "Sharing", click "File" here.

2, then we see a new window, in this window can edit the title, description, format, resolution, quality and compression speed. Note that the format section only "Video + audio" and "audio" two optional, the video is exported to the MOV format file, not to allow you to choose other video file format.

3, after all the choice, click Next, it began rendering compression, the process is only waiting. We can view the process of the task in the upper-right corner.

　　It is worth mentioning that, if the choice of high quality output, then imovie will lead a low quality version, directly can play, and then continue to render high-quality files. This is still very human.
