Reduce File Size of QuickTime Movie (MOV) using iMovie
[Sep 12, 2011]
When I do a screen recording on my Mac, I got a 1.5 minutes MOV file of about 8 MB in size. I was able to reduce the size of the MOV file by import it into iMovie, then add the imported file to project and then export it using "Share > Export using QuickTime...".
By using this command, I can set the frames per second of the MOV file to 8 frames per second. I also select single pass to export the movie faster. You can also set the quality of the movie to low or medium to further reduce the file size, but I use the default high quality setting.
One more option that can help make the file smaller is to set the size of the movie to your custom smaller size, for example, my movie is 1600x900, and I set the size to 640x360 when exporting. The result MOV file that I can get is about 2 MB in size, which is about 4 times smaller.
