[Tutorial] How to Crop iPhone Footages

It's quite simple to crop videos shot by iPhone with VideoProc. To do this, save your iPhone videos you wish to crop to your computer, open VideoProc, and use the following steps.

Step 1: Import an iPhone video

Click the Video icon on the main interface and the Video window appears. Click the add video tab at the top and select a video to load. You can directly drag and drop the source video to the Video interface. If you want to add more than one video captured by iPhone for processing in batch, repeat the step. It also allows users to load a video folder by clicking the Video Folder tab at the top. Once you import the video, select a video format as output from the Target Format list.

Step 3: Crop your footage

Check the box Enable Crop to turn on the function. Crop borders display on the edges of the video image. The crop box can be moved and resized. Click the Preset drop-down list and select a preset. There are quite a few presets. Select the preset you need.

In the Position, adjust the values in the Left, Right, Top, and Bottom fields to fine tune the crop box. After you've all set, click the Done buttons to make it applied.

Free - Enable this preset to freely drag the corner and edge handles to set the crop boundaries in your video to any size.

16:9 - This is a preset for a 16:9 crop.

For example, if your videos are shot by iPhone X with an aspect ratio of 19.5:9, and you want to crop the iPhone footages for Instagram that requires ratio 1:1, 1.9:1 or 4:5, we recommend you to set the crop box to 1:1 under the preset drop-down list.

Does cropping affect the iPhone video quality?

The answer is yes. The cropping process includes decoding, making the change, and re-encoding. Re-encoding means a certain degradation to image quality. The degree of the loss depends upon how extreme the crop is and the tool you choose. It's impossible to export the cropped footages from iPhone without any quality loss. However, with the right program like VideoProc, you can get the best result - there's no quality difference your eye can tell between the original file and cropped video.

The differences among cropping, trimming, resizing, and changing aspect ratio

During video editing, some users have trouble figuring out the differences, especially cropping vs trimming. Read the following information to help understand these terms and use them accordingly.

Cropping means reframing the video. It is used to zooming in on the subject, remove unwanted parts of video images, or to fit a certain size of a screen/display. Video aspect ratio can be changed by cropping.
