Understanding Video Compression

Video compression is a process that reduces the size of video files by removing unnecessary data. This is typically data about colors, resolution, and frame rate. However, all these factors contribute to the video quality, so removing them reduces the quality.

The key to effective video compression lies in balancing quality and file size. iMovie's Compress Video feature helps you do this by offering different compression levels.

Different Compression Levels

iMovie offers three compression levels: High, Medium, and Low. Here's what each one does:

  1. High: This maintains the best video quality but has the largest file size. Use this for high-end projects where quality is paramount.
  2. Medium: This finds a balance between quality and file size. It's a good middle ground for most shareable videos.
  3. Low: This provides the smallest file size but with some loss in quality. Use this for low-key projects or when storage space is a concern.

After compressing your iMovie video, it's important to monitor your storage use to ensure you don't run out of space.
