Question: I'm looking for a way to easily convert horizontal videos into vertical ones for mobile viewers.

If you need to convert horizontally shot videos to vertical for mobile viewing, Kamua is a good option. The browser-based video editor uses AI to automate some processes, including the conversion of horizontally shot videos to the vertical format. Its AutoCrop feature is just one of several useful options, including multi-select abilities, overlays and social media preview options, that make it easy to adapt your videos for mobile screens. A free tier is available, and you can upgrade or downgrade as needed with flexible pricing plans.

Another option is Big Room, an AI-powered video conversion tool geared specifically for converting landscape videos into vertical format for TikTok, IG Reels and YouTube Shorts. It also can automatically caption videos, making it a good option for creators who want to quickly adapt their videos for different social media platforms without sacrificing any original rights.

If you want a more advanced video editing experience, check out Vizard. The AI-powered tool not only converts videos to vertical, but also offers AI clipping, caption translation and timeline editing. It's good for creators who want to spend less time editing and more time engaging with their audience by optimizing their videos for different social media platforms.

Last, OpusClip offers AI-powered video conversion and curation, including auto reframing and animated captions. It also offers more advanced features like a virality score to assess clip performance and scheduling. It's good for individuals and professional teams, with tiered pricing plans to accommodate different levels of use.
