Change Video Resolution and Dimensions
Resize a Video Without Stretching the Picture
Change video resolution by entering a width and height in pixels or scaling by a percentage. With the aspect ratio locked, 1920×1080px becomes 1280×720px when you set the width to 1280px. Choose a preset and scaling method, then check the codec-safe dimensions shown in the preview. Lower resolution can reduce file size; use Compress Video when a size limit is the main requirement.

This changes pixel dimensions. The file size also depends on duration, codec, bitrate and audio.
