Video Size

A video size defines the width and height of a video frame in pixels.

For example:

1920x1080

means:

• Width: 1920 pixels
• Height: 1080 pixels
• Resolution: 1080p / Full HD

Higher resolutions generally provide more visible detail, but they can also require larger files, higher bitrates, and more processing power.

Example

await NyxConverter.convertTo(
  filePath,
  outputPath,
  size: NyxSize.w1280h720,
);

This converts the video to 1280x720 (720p HD) resolution.
