Hi guys,

iMovie can't change aspect ratio, right? No matter how I crop the video, move the position of the window, drag the handle to reframe it, the video is always at 16:9.

How do you change the aspect ratio or I should say crop a video freely on Macbook? Other built-in apps, QTP and Photos do not work.

I know FCPX can crop, but it's not within my budget.

TIA

Hi,

I found MPEG Streamclip which is able to change video aspect ratio. You can download it for free from this link.

I kept searching online the other day, and figured out what I need is actually cropping videos which including reframing videos at a certain aspect ratio and at a freeform. This article rounded up lots of video cropping software, and I tried some free and lightweight tools on the list. They all worked quite well for me.

I will leave the link here for anyone in the same situation.

Click on the button marked crop on the tool bar section. You will see a pop-up window with resolution options of 16:9 and 4:3 to automatically resize the video to the appropriate screen size.

This is an old method invalid in the latest iMovie. What's the version of yours?

To change a project's aspect ratio:
Click to select a project in the Project Library, or open a project so that it's showing in the Project browser, and then choose File > Project Properties. ...
Choose an option from the Aspect Ratio pop-up menu.
