About
A YouTube Short is a vertical video, and a widescreen recording uploaded as one can show bars or lose its sides. This page opens the free aspect ratio converter already set to 9:16, so a horizontal clip can be reframed for Shorts without being recorded again. Choose 1080p or 720p, and the export keeps the original sound.
Shorts are often built around one idea: a tip, a quick explanation or a reaction. For a talking head, Blur keeps the presenter large in the centre with a softened copy of the scene behind them. For a screen recording or a slide, Colour keeps the whole screen in view with plain bars around it. Crop suits a moving subject that should fill the screen, and Zoom with the move sliders keeps it inside the frame.
Shorts show the title and channel name over the lower part of the picture, and the like, comment and share buttons down the right side. Keep faces, captions and key objects clear of those areas. The safe zone checker shows approximate margins for YouTube Shorts, so you can check the frame before you upload. YouTube changes its layout over time, so check its current guidelines too.
