1 answer

To optimize the file sizes of high-definition videos without compromising visual quality, the following technique from your options can help:

Compressing the videos.

Compression techniques, such as using a codec like H.264 or H.265, can significantly reduce video file sizes while maintaining good visual quality.

The other options would not effectively reduce file sizes:

  • Adding more visual effects would likely increase file sizes as it adds more data to the video.
  • Removing audio may reduce the overall file size, but it also eliminates an integral part of the video experience.
  • Increasing the resolution would increase the file size, as higher resolutions contain more pixel data.

Thus, 'Compressing the videos' is the best option to reduce file sizes.
