Delivering videos according to the aspect ratios defined by social media for multiple devices and platforms is a growing challenge. The continuously rising volume of vertical videos and the corresponding increase in video<\/a> traffic on mobile devices (now up to 57% of online videos watched) have only exacerbated the situation, with no letup in sight.<\/p>\n

Reality is, smartphone users hold their phone vertically while scrolling or browsing online content, including videos that are not optimized for mobile devices. It simply doesn\u2019t occur to those users to switch to horizontal mode for an enhanced view, or it doesn\u2019t feel worth their effort. This means that providers of online content must make sure their videos accommodate all viewing devices, ideally through automation.<\/p>\n

Cloudinary, which for years has been performing automated cropping of images for size economy and compliance with aspect ratios, can now do the same for videos, adding to its already powerful video solution. Impressively, Cloudinary\u2019s content-aware cropping<\/a> capability identifies the must-keep sections by analyzing videos through advanced AI and machine-learning techniques, churning out intelligently downsized videos in any aspect ratio. It\u2019s as simple as setting the crop mode to fill<\/code> and the gravity to auto<\/code>.<\/p>\n

\nWhile there are several emerging tools and services, such as CognitiveMill, which claim to offer similar automated cropping, they often rely on simple scene-by-scene visual analysis. In contrast, Cloudinary’s advanced AI and machine-learning techniques provide more accurate and intelligent content-aware cropping. There are also other tools like Canva, PowerDirector, Flixier, and Kapwing. However, what sets Cloudinary apart is not only its robust AI-backed capabilities but its comprehensive video solution that caters to multiple aspect ratios and platforms, making it a preferred choice for content providers. \n<\/p>\n

Rotate or Move On: The Challenge with Video on Mobile<\/h2>\n

Nearly half of all smartphone users watch short-form videos or live posts at least once a week. Because most people hold their phones vertically for comfort, yet videos are best viewed horizontally, many folks shy away from the trouble of rotating their phone and waiting for the video to update. The solution? Have videos play with the correct aspect ratio<\/a>, eliminating the rotation step and avoiding accidental dropping of the phone.<\/p>\n

Additionally, given the monumental role of social media in video consumption, you must deliver videos on those platforms across all devices. The chart below showing the various aspect ratios required for optimally delivering videos for Facebook and Instagram, clearly demonstrates the challenge, especially if large quantities of videos are involved.<\/p>\n

Introducing Automatic Content-Aware Cropping<\/h2>\n

You can now automate all your video cropping with Cloudinary\u2019s automatic content-aware automatic cropping functionality. No more time consuming manual editing. Cloudinary has developed a complex deep-learning algorithm that analyzes frames from the video and identifies where the most interesting areas are. From this analysis, a heatmap is produced and then used to crop the video intelligently.<\/p>\n

The cropped video will now follow the most interesting area of the video throughout the duration, ensuring that your videos retain all the important features you wanted when you filmed them, while filling the screen no matter the aspect ratio.<\/p>\n

As we mentioned above, all you need to do is set the crop mode to fill<\/code> and the gravity to auto<\/code>. This will begin the process of analysing the video. We recommend performing this on upload as an eager<\/a> transformation to ensure the analysis is complete before delivery (or alternatively using the explict<\/a> method before delivery on a video already in your account). Once that analysis has been performed on a specific video in your account, you can deliver your content-aware video in any aspect ratio you need; Landscape, Square, Facebook Vertical, Instagram Story Vertical.<\/p>\n

Automatic Cropping Versus Default Cropping<\/h2>\n

Let\u2019s take a look at how content-aware automatic cropping compares with the standard center crop. Notice how the default crop only has the dog in shot for a short period of time when he passes through the center of the frame. With automatic cropping, this impressive frisbie catch stays in shot throughout the video, despite starting on one side of the frame and finishing on the other.<\/p>\n
