How To Resize Video In Imovie Iphone

How to upload your video/audio assignment

Compressing a video file using Apple iMovie (MAC)

This guide will walk you through exporting your video from Apple's iMovie which is easy to use video editing software that comes free with all new Macs.

Please note: These instructions are for the latest version of iMovie on a Mac (version 10). To check which version you have installed go to iMovie - About iMovie.

Step 1: Edit your movie as usual

Edit your movie in iMovie as usual - when you are happy with the finished movie and ready to export move on to step 2. For help with editing your video in iMovie see http://help.apple.com/imovie/mac/10.1/

Step 2. Share your movie using the 'File' option

Click on the 'Share' icon (1) and you will see a window with a number of export pre-set options. Choose the one that says 'File'. (2)

Step 3. Look at the options for changing the Resolution and Quality of your movie

In iMovie 10 Apple removed the capability to alter the video compression settings using Quicktime but you can still reduce the file size to ensure it is under 500 MB. The screenshot below shows the original file size of the video which is 3.38 GB (1) - far too big to upload as your assignment. In order to reduce this to under 500 MB you need to adjust the Resolution and Quality (2).

Step 4. Tweak the Resolution and Quality until the file size is less than 500 MB

In this example I have set the Resolution to 960 x 540 via the drop-down arrows and the Quality to High (1). This has brought the file size down to 198 MB which is below the 500 MB limit. Click on 'Next' to proceed (3).

Step 5. Save the exported file to an appropriate place

In this example I have named the file 'Test Movie' and set the save location to the desktop. Click on 'Save'.

Step 6. Wait for the export process to complete

There is a little progress icon towards the top right of the window - when your video is finished exporting you should get a message saying 'Share successful.' If you click on 'Show' you will be taken to your exported video ready for uploading to Solent Online Learning.

Step 7. Finally - Check the file size

One last step - just make sure the file size of your exported video is under 500 MB. Select the file in the finder and in column view (1) you can see the exact size of the file (2).
