The Quality section adjusts the quality level for images, sound and video inserted in the course. The higher is the quality of the media, the larger is the size of the output files. Click the link in the Quality field to change the settings.

In the quality settings, you can select one of the ready-made presets for the following situations:

  • For displaying courses in high quality
  • For standard viewing
  • For low-speed connections

You can also configure your own quality settings and save them as a separate preset.

When creating a custom preset, you can change three parameters:

  • Image Compression
  • Video compression
  • Audio Compression


Image Compression
Image Compression            

Smart compression automatically chooses which type of compression to apply to a particular image in the course: lossy or lossless. The result is the most optimal in terms of quality and size.

Lossy compression will save all images from the course to .jpg format with the specified compression settings.

Lossless saves images to .png format. This will ensure the best quality, but the output files will be large.


Audio Compression
Audio Compression            

You can set the sound quality in your published course from 0% (low quality and small size) to 100% (high quality and size). The recommended quality is 50% or higher. Note that the higher the audio quality, the larger the final file size.
 

Note: Audio compression settings affect the audio quality of video files as well.


Video Compression
Video Compression        

You can set the video quality in your published course from 0% (low quality and small size) to 100% (high quality and size). The recommended quality is 50% or higher. Note that the higher the video quality, the larger the file size will be.


You can save a custom preset by clicking the Save Preset button. To delete a custom preset, click Delete.

Enter a name for the profile and click OK.

The saved profile will be added to the list of available profiles. You can select it when publishing all the courses on your computer.
