Convert landscape footage into vertical videos with AI
Portrait PRO is a browser-based tool that automatically turns landscape clips into portrait-format videos using advanced artificial intelligence. Its core engine analyzes every frame, detects people and other focal objects, and crops the image so the most important elements remain visible. The output is a clean portrait composition that's ready for mobile and social viewing.
How subject-aware cropping works
The application applies a frame-by-frame detection model to locate and separate subjects from the background. Once identified, the crop window follows the action smoothly, avoiding abrupt cuts or misplaced framing. This preserves the narrative and visual focus while changing the aspect ratio.
Key advantages for content creators
- Keeps the main subject centered and visible throughout the clip, avoiding awkward or incomplete crops.
- Reduces production time by removing the need to manually reframe each shot.
- Improves suitability for social and mobile platforms by delivering properly formatted vertical videos.
- Enhances viewer engagement with professionally framed portrait compositions.
Paid alternative worth considering
UniFab Video Enhancer (commercial) is an AI-driven editor and video generator that can also convert formats and polish footage. It combines automated reframing with editing tools, helping creators speed up post-production while maintaining focus on the scene’s important elements.
Who benefits most from this tool
This solution is particularly useful for social media influencers, marketers, and small production teams who need to repurpose horizontal footage for vertical-first platforms without a lengthy manual editing process.
