## Overview Video Crop by Wiro crops an existing video to a new frame region. You choose an exact pixel crop or pick a target aspect ratio. The model keeps pixels as-is and removes the rest, so it won’t scale or stretch the footage. This solves fast reframing for Shorts, Reels, and ads without a full edit timeline. ## What you can build - Convert landscape videos into portrait crops for TikTok, Reels, and YouTube Shorts - Remove black bars, UI edges, or unwanted borders from screen recordings - Create square (1:1) and feed-friendly crops from a single master clip - Standardize framing across a batch of clips before running downstream video models - Crop to ultra-wide banners (like 21:9) for website headers or hero sections ## Inputs - A source video file to crop. Use a common format like MP4, MOV, or WebM. - A crop size in pixels, given as both a width and a height. Provide both numbers together. The crop can’t be larger than the source frame. - A preset aspect ratio to crop to when you don’t provide a pixel width and height. Common presets include 16:9, 9:16, 1:1, 4:5, 4:3, 3:4, and 21:9. - An optional horizontal offset in pixels from the left edge. Leave it blank to center the crop. - An optional vertical offset in pixels from the top edge. Leave it blank to center the crop. ## Outputs - One cropped video file. - The output frame size matches your crop box. If you crop by aspect ratio, the output uses the largest rectangle of that ratio that fits inside the source. - The output keeps the original content inside the crop region. It does not resize the video to fit. ## Limitations - If you set a pixel crop, you must provide both width and height together. - The crop region can’t exceed the source frame size. - Offsets that would push the crop outside the frame won’t move the crop out of bounds. - This tool crops only. It won’t upscale, enhance, or “smart track” a subject. - Videos with unusual metadata, rotation flags, or variable frame sizes can produce unexpected framing. - Low-quality or broken inputs (corrupted files, incomplete MP4 headers, or inconsistent encoding) can fail to process or return incorrect crops. ## Safety & compliance - Only upload or process videos you have rights to use. - Don’t submit videos with sensitive personal data unless you have consent and a clear reason to process it. - Cropping can remove context. Review outputs before publishing if the clip could be misleading.
