Convert horizontal videos to 9:16 portrait format by using smart cropping that prioritizes faces and key elements, powered by FFmpeg and OpenCV encoding.
Smart crop for vertical video uses MediaPipe face detection to identify subjects and dynamically adjust the framing, ensuring faces and key elements remain centered in the 9:16 output.
The best way to batch resize multiple videos is using a script that processes an entire folder, applying smart, center, or letterbox cropping modes to generate 9:16 clips automatically.
Yes, the tool works with OpenCV for image processing and MediaPipe for face-detection-based focus, utilizing FFmpeg for the final video encoding when available.
The available cropping modes for converting horizontal video to vertical are smart, center, and letterbox, allowing you to choose between facial detection focus, static centering, or pillarboxed framing.
