Apple has made iPhone the best camera to capture high-quality videos in 4K, 1080P, and 720P. However, the iPhone videos are usually not ready for sharing or plaback right away. For example, your video may end up distorted on Instagram as Instagram displays video in 1:1 while iPhone takes video in 16:9 or 4:3. The large file sizes caused by the higher resolutions or slow-motion recording modes also limit the use of iPhone videos. In this article, you will learn how to crop iPhone video to the right aspect ratio, and how to compress iPhone videos to smaller sizes, without quality loss.
When your play footage at 720x480p, namely 720:480=3:2 on a 16:9 display, or upload the same video to Instagram, you will find the video distorted. This is because the images won't fit properly if the screen is narrower or wider than the image. Normally, iPhone video size issues are described as vertically or horizontally stretched image, or non-stretched image but with horizontal letter-boxing or vertical pillar-boxing.
As iPhone videos are normally recorded in fixed aspect ratio, sometimes we need to adjust the iPhone footage to 8x10 (4:5), medium format (which meant many things and ranged from 1:1 to 6:17 panoramic), and full frame (3:2), or it may cause the video look distorted or out of shape when user want to fill the entire screen of a device with a different aspect ratio. For example:
Different aspect ratios are used for different applications or platforms. For example, US and UK use 1.85:1 as the widescreen standard in cinemas while 16:9 is the universal high-definition and digital video and television format of the 21st century. Below are the use of most common aspect ratios.
To resize iPhone clips to let the landscape or upright video show in the right aspect ratio properly, VideoProc Converter AI will help. It can crop iPhone videos to any size you need without quality loss, or without black bars to fit any displays. First, free download the iPhone video resize app on your computer:
Note: The Windows version now supports AI-powered Super Resolution, Frame Interpolation, and Stabilization to enhance video and image quality. These AI features are not yet available in the Mac version but will be coming soon.
Step 2. Select an output format. Select an output format from the Target Format column at the bottom of the interface. If your iPhone video is recorded under High-Efficiency mode, select MP4 HEVC; if it's recorded under Most Compatible mode, select MP4 h.264 to retain the best quality.
First, click the button with a gear icon. In the parameter setting page, you can adjust the aspect ratio directly. Then you can change the aspect ratio to 16:9, 4:3, 3:2, 5:4, 1:1 and many more. This option will simply shrink or stretch the iPhone videos to the specific aspect ratio. However, simply adjust the aspect ratio may distort the image.
Second, in the Resolution box, click custom and enter into a number based on the aspect ratio you need. For example, if you want to resize the iPhone recorded video into 1:1 for Instagram, enter into 800x800, 700x700 or numbers like that. Below we have listed the most commonly used resolutions for different aspect ratio. Then check the Expand Video box which will shrink or enlarge the image and add letterbox when it is required to help the image fill the full screen. This will remain the original image undistorted or stretched.
Click the Crop button and enter into the editing window. Click Enable Crop. In the Preset options, you can select a specific aspect ratio like 16:9, 4:3, 1:1 and start cropping, or select Free to manually crop iPhone videos to any customized aspect ratio of any displays. You can drag and move your cursor to select the crop area or enter the specific position below. Cropping ensures that the iPhone video is resized without black bars, but it will cut off excess picture information.
Step 5. Start to resize iPhone footages. After all the settings, click Run to apply all the adjustment. The iPhone video resizer will finish the job fast due to the support for Level-3 Hardware Acceleration (Intel QSV, Nvidia and AMD).
The increasing resolutions also make iPhone video too big in many cases. For example, the size of iPhone video at 4K 30fps in one minute takes up 300MB (170MB using HEVC). There are many apps like WhatsApp and Email services have strict limits on the video size that you can share or send. Even if there is no restriction, sending large files on iPhone is quite a pain. In many other cases, you will need to reduce iPhone video size. Below are some common size limits you may meet:
Cloud storage services all have limits on the size you can store for free. For example, iCloud allows 5GB free storage, Google Drive 15GB, and Dropbox 10GB. The limits seem enough compared with that of social media or emails, but think about the dreaded times when the 16GB iPhone is soon filled up by various videos and pictures.
Videos always take large space on iPhone. The good news is that iPhone storage has increased from 16GB to 512GB (iPhone XS). But for those who want to move their large collections to iPhone and turn it as a movie center, they will also need to compress iPhone video size. Plus, more free space on iPhone will help the device run faster.

Step 2. Resize iPhone footages to smaller. Video size is determined by many factors like resolutions, formats, bit rate, etc. Below we can use VideoProc Converter AI to adjust the iPhone video size in different ways.
Go to the Video tab on the bottom and select an output format from the Target Format. iPhone records videos in H.264 or HEVC H.265. You can also convert iPhone formats into suitable files to reduce the size to a large extent. For example:
HEVC - to save file size on iPhone, first, record videos in HEVC. And when your iPhone video is recorded in H.264 HD or 4K, switching to H.265 can save half the size with the same good quality. Currently, HEVC is getting more support among players, editors, websites and other platforms. It's the first choice for high-quality videos.
WMV- the format from Windows is good at keeping the file size small and reserving good quality. Compared to H.264, it can save up to 60% video size. The format is widely used for video email, web video, and permanent storage on a PC.
Hit the gear-shaped Option button to enter into the video setting page. Different videos have different sizes due to the inherent parameters. By adjusting them correctly, you can resize iPhone clips easily:
Resolution - higher resolution has more data and therefore results in a large file size. For example, a 4K video has more horizontal lines than 1080P, thus the more data leads to a large file size. Unless you're going to play 4K iPhone videos on a 4K UHD TV, downscaling 4K to 1080P or 720P will reduce the iPhone video size without visible quality loss. To downscale 4K iPhone videos to 1080P or lower, select 1920x1080 or others from the drop-down menu of Resolution. Don't forget to check the box Expand Video, it will add letterbox if necessary to keep the video image undistorted.
