On a Mac, how can I tell how many GB I have in a single video in iMovie?

That is truly an excellent question! Unfortunately, I am not entirely sure of the answer, so therefore I wish you the very best of luck in finding it! Hopefully, there will be someone who knows this! Once again, good luck!

If the video is still in the project stage in iMovie, you cannot get info about it as suggested above.

The way that I know is to:

1. Highlight the project in iMovie

2. Click Share > YouTube

3. Down the bottom where is says 'Size to publish', you will see a little 'i' at the end of the line.

4. If you place your cursor on that 'i' in any line, it will show you the project size at that particular frame size.

5. You don't have to go any further, just look at the sizes.

If you want a smaller file size, try exporting the video to QuickTime and select the mpeg4 codec rather than the standard/default H.264.
