Video Orientation Converter

The Video Orientation Converter transforms horizontal video to portrait orientation for mobile-first viewing. It accepts a source video and outputs a vertical file optimized for platforms like TikTok, Reels, and Shorts. Conceptually, the tool adjusts the frame to the target aspect, choosing between cropping the sides or padding with a background color to fill unused space. This preserves the primary content while delivering a native 9:16 or other portrait format. The approach is deterministic: given input dimensions and a target aspect, the system computes the exact crop rectangle or padding height, then re-encodes to the requested format. Beneficiaries include social media managers, editors, and creators who need consistent portrait assets without manual editing. Unique value lies in automatic safe-area handling, rotation options, and explicit output dimension reporting. Core features include input validation, orientation calculation, mode selection (crop or pad), optional rotation, and straightforward export to MP4 or MOV. Typical use cases include repurposing landscape footage for Reels, applying letterboxing when content cannot be cropped, and batch-processing multiple clips with consistent output settings. The tool emphasizes reproducible results, enabling downstream editing pipelines and quality control in media workflows.
