Movie Resizer

The movie resizer accepts a video file and target dimensions, then scales the frames while preserving or adjusting the aspect ratio according to user choice. Conceptually, it computes a scaling factor based on the larger target dimension and applies it to all frames; optional padding (letterboxing) can fill unused areas. It supports common input formats and outputs a single resized file, with optional re-encoding quality settings. The tool serves creators, editors, and production teams needing platform-ready assets, and is valuable when preparing variants for YouTube, Instagram, or corporate sites. Core value lies in predictable outputs, controlled encoding, and reduced manual editing steps. Key features include: input validation, aspect-ratio handling, preset targets, and batch-ready processing for multi-output workflows. Typical use cases include resizing clips for vertical or square formats, standardizing assets across a project, or converting to a specific container. The architecture favors deterministic results and traceable output settings, enabling reproducible pipelines and easier QA.
