#2: Use a Video Editing App
It can take a lot of time to shoot in different dimensions or edit the footage to fit particular frame sizes. A much easier option is to use a video editing app to do the heavy lifting for you.
Option #1: InShot for Mobile Edits
One great option is InShot, which lets you resize your video content for numerous formats.
To do this, simply open the mobile app, import your video, and select the “Canvas” option.
From here, you can automatically resize it to various aspect ratios — everything from 1:1 to 9:16.
If your video is somewhat lengthy and you want to make it shorter, you can also use InShot to trim and split your footage to a custom length.
And like all great mobile video editing apps, InShot comes packed with design features, like filters, background colors, music, text, and more!
Option #2: Filmora9 for Desktop Edits
While you may recognize the Filmora name for their mobile app Wondershare FilmoraGo (formerly Wondershare Video Editor), the company also has a desktop app that’s super popular among social media marketers – partly because it’s so easy to use!
As soon as you import your video file, you can arrange clips in your timeline, clean up your footage, edit out unwanted parts, and more.
To resize your video, simply select the clip in the timeline, right-click on the clip and choose Crop and Zoom, or click the Crop icon.
In the pop-up window, move and adjust the rectangle to surround the area you want to crop. You can also choose the preset from the following preset dimensions: 16:9, 4:3, 1:1, or 9:16.
From here, as with InShot, you can trim and split your clip, and have a number of video effects like filters and transitions.
